We had the opportunity to compete in the 2025 Mammoth Sniper Challenge at Fort Chaffee. The match director Chris Andrews commented that this might have been the toughest Mammoth yet due to constant rain day 1, heat on days 2 & 3, and rain & thunderstorms the third morning. The dropout rate was close to 50%. In the end only 44 of 80 finished the event. We were lucky to edge out a top 20 finish at 19th place and finished Mammoth our first time competing. Over three days we had 6 rucks totaling 29.7 miles with a sub 16 min/mile pace carrying about 60lbs worth of gear.

Below is a list of the gear and food I packed. To the food list I added (2) oatmeals and (3) mini–Cliff Bars. Last minute adds to the gear list were a lingerie laundry bag, Vaseline, and poncho. A grand $4.59 from Walmart in total. My teammate carried 50 rounds of 6.5CM ammo for me. After the event on the drive back we summarized our findings and those can be found at the end of this write-up.



Weight

I took out the alternates; dry bag and cold weather gear. I stepped off with a total weight of roughly 64# with 56.5# in my ruck

Failures

My Kuiu Pro 3600 had a tear in the side at the seam and the load straps were frayed, pretty significantly, from rubbing on the frame. The load strap damage is from improper use feeding them through the frame. Kuiu was gracious enough to get in the mail a new harness and a store credit for my bag with a tear. My headlight, Black Diamond Cosmo 350, died Friday night and REI replaced it without a receipt. My Patagonia rain jacket had a failed zipper and it is enroute to Patagonia for repairs.

Not Recommended

I wore the GoRuck Mackalls and would not recommend them for 3 days and 30 miles. I would go with a mid-boot. I had 3 blisters and 2 hot spots. Taping my feet made one of the blisters worse. I read “Fixing your Feet” prior to the event but had little to no experience with hot spots and blisters during training.

Changes in Kit by Discovery Day

Day 1

• With my headlamp failing I wish I had packed a backup headlamp. Having to use your phone for everything sucks.
• I would add medium weight poncho for if your rain jacket jacket fails, to cover both shooters, or to cover your bag
• My sharpie and ball point pen did not do well in the rain. I would add a Rite in Rain Pen
• I would add a rifle rain cover to protect my rifle & optic from the elements.

Day 2

• Add Small mat to sit / kneel on to save your legs, knees, and feet.
• Add Small lightweight chair to save your legs, knees, and feet.
• Add Lightweight Sandals to let your feet air out
• Add Ranger Shorts to ruck in or sit around camp in

Day 3

• I would take more food. Probably an additional meal per day. Between active and resting calories we burned approximately 4200, 4000, and 3400 respectively per day. I only packed on average 2350 calories per day
• A medium weight tarp to wrap all your gear in when it’s raining
• Change to a tent that has more height and is easier to setup. Right now I have 8 stakes and 3 poles. Some of the lightweight hunting tents I am looking at have 4 stakes and a single pole. Our tent did very well keeping us dry. The tent never lost a stake or came off the ground with the storms. I would recommend an insert (bottom or tub) with the tent to keep water out
• I packed 4 pairs of socks and 2 pairs of underwear. I would pack 6 pairs of socks and 3 underwear.
• I packed 3 shirts and 2 pants. I would pack 2 shirts and one pair of pants.
• Multiple sleep aids did not work as well; Olly Gummies, Unisome, Advil PM, and Ashwaganda. The only thing that worked was NyQuil.
• More Ibuprofen / Advil. We didn’t have enough. I think I had 8 per day.
• Instead of foam inserts for ear pro pack something like Surefire Sonic Defenders.
• Nalgene for carrying premade coffee, oatmeal, or ramen. We had to use the provided plastic water bottles.
• Paracord for a clothes line to dry out clothes or fix failed backpacks.
• Add Ramen noodles & oatmeal to the food list.
• Lightweight dry bags to stuff items like a sleeping bag, pillow, clothes, ammo, etc.
• Another option instead of tarp, gun condom, etc. would be a pack cover
• A lot of guys were taking Pre workout before the rucks and it seemed to work out well

Closing Thoughts

I rucked twice a week, probably 3-4 miles average per ruck with final pack weight, and never rucked further than 6.5 miles. I did this for about 4 months leading up to the event. I ran and did bootcamps other days of the week. I felt confident going into the event. In hindsight, I wish I had rucked twice a day for 3-4 miles each ruck a couple weeks or month leaidng up to the event to get my feet and body conditioned to that level of load and demand. I also wish I had done more running interval training with pack weight. My teammate did this and fared better than me on the final ruck.

I severely underestimate calorie consumption and wish I had packed more food. It’s hard to explain, but you are constantly moving. Either rucking, packing, unpacking, shooting, setting up camp, packing up camp, cooking, etc. It’s a gear management marathon. You are just constantly moving. There were a few times a day I could lay down in the shade, hopefully under a tree, but those were in the minority by far. Any time you can get off your feet either on a mat, chair, or shooting bag it needs to be done.

There is something about being out in the elements for three full days that just zaps you mentally and physically. We had about six hours of rain on Friday and everything got soaked. It wasn’t particularly cold, 60degF – ish, but people were shaking they were so cold. I made the mistake of changing my socks immediately after the first ruck and the new pair got soaked with the rain. I was already down 2 pairs of socks, and it wasn’t even 9am the first day of the event. We spent the majority of the first day in the rain. It didn’t really stop until early afternoon, allowing us to dry up before the final ruck. I don’t think I was dry until like 3-4pm. The heat on days 2 and 3 just drained me. I did well with a hat, long sleeves, and long pants, but still it’ll just zap you and I am from the Southeast and accustomed to the heat. It wasn’t particularly hot either, in the mid 80’s.

Another thing I didn’t expect was sleep deprivation. We didn’t get back to camp on the first day until like 6:30. Setting up camp, cooking, drying clothes out, setting out clothes for the following day, inventorying, etc. it was close to 9 before we got in bed. With an early rise all morning of 4am-4:30am

Looking for a single-stage trigger for a Remington 700 clone. I shoot a left-handed action, so it would either have to be a left-handed trigger or one that I can remove the safety from, like a trigger tech.

It was on my 6.5cm hunting rifle, but I want something lighter. Scope is in good condition and functions great. I've shot it out to 900 yards, and it tracts like it should. It has some light scratches on the objective lens that can be seen at the right angle, but they don't effect the clarity.

Locking windage and zero stop can be set under zero on this model.

Just PM me, don't make it easy for scammers by posting "PM sent".

I'm probably the best stocked I've been in a while right now. I have plenty of Vortex, Nightforce, Swarovski, Kahles, Zeiss, Leica, Leupold, and ZCO just to name a few. As always, call for best prices and let me know if you have any questions at all.

I wanted to let everyone know we are working to produce some of the missing MSR/PSR parts. These are awesome rifles, but it seems like there are more chassis’s and actions than bolt bodies and other small parts.

Currently we are working on the bolt stop, bolt body, and firing pin assembly.

If anyone has knowledge about the system,
experience or connections in producing a small run of parts like this please let me know.

Please comment with which parts you need as well as the quantity.

I will keep everyone updated with the progress here as well.

The parts will be marked to indicate that they are not factory original parts. But should function and appear like the factory parts.

When we get to production, Kace at Raider Outdoors will be handling distribution in a separate post. https://raideroutdoors.com/

Well...I am officially stumped!!!
I use the 6.5cm sac sizing die with .285" shoulder/neck bushing and .2625" expander mandrel with alpha munitions ocd LRP brass. When I shoot my zermatt origin action with proof ss prefit barrel and oss suppressor I always get a ton of fouling that goes past neck down to the bottom of the shoulder and sometimes past that. Ive tried everything to fix it and nothing works..different bushings/expander mandrels I bump the shoulder back .002". I just just got in a new batch of alpha brass and the necks on some were messed up so I ran them all through my sac sizing die that way I always to make sure my shoulder is set where it normally is (I've got a tight chamber) after i did that I went and shot some and the fouling stayed on the neck and didn't go past that onto the shoulder and further. I cant figure out what's different. Everything reloading wise is the same. gear is the same only thing difference is that's its new brass but I did resize it all before using it and with all my brass I always anneal before resizing ( not with the new brass). Can anyone tell me what the heck is happening and how I can correct it so my fouling isn't going past the necks and into my.chamber anymore. What made the new brass different even with the sizing being the same.
Thanks all,
Justin
1st pic is brass with multiple firings. 2nd is new and sized brass

Has anyone used this chassis long enough to give a solid review? Just wondering how it holds up and if there’s anything I should know before buying. I’m in love with the looks of it but I know that can become an issue at times. I was going to use a MDT ACC to build a competition rifle but this Woox Furiosa is just too cool not to consider. Also is there any other really cool looking chassis I should consider instead?

I have a Proof Heavy Palma 26" Zermatt TL3 prefit with 623 rounds on it. 300pcs of virgin Winchester 243 brass, and a Redding 6 SLR FL sizing die with a Tin 268 bushing installed. And a Redding Micrometer 243W Seating die. Chambered by Harless Precision in Colorado Springs. This is the little brother to the 6 Comp Match. You can run H1000, RL26, 23, 4831, and other traditional magnum powders for long barrel life and low chamber pressure. Easily push 115 DTACs at 3050fps without breaking a sweat. This was my 3rd 6SLR barrel and I threw the old brass out. It's the easiest case forming you can do. Just size the brass and you have 6SLR.

Not sure which gun.

WHen you remove/clean your brake or muzzle device then replace how repeatable is your zero? My can was pretty repeatable, but that was a QD with a brake/FH attached.

Now I'm absolutly OCD so i'mprobably going to re-zero regardless

I thought this was an interesting YouTube series this guy has going. Cool to see all the different rigs.
Might not be as entertaining to some more seasoned shooters, but I think it’s fun.

Suppressor is both Intermediate (300 Supers, 5.56, 308) and Handgun (9mm) rated. It also has a HUB interface.

Does there exist a HUB adapter that will adapt to 9mm tilting barrel handgun (piston, I dont think there is another system that works in this app), and also adapt to non-tilting barrel interfaces that are larger than 3-lug? (that is, larger than PCC subs thereabouts).

Why would someone ask for such a thing, right? Say someone has a "Go" bag with a collapsible, or folding, or takedown short barrel AR pistol in Intermediate caliber and also keeps a semi-auto handgun in the same bag. Switching from AR to handgun could require a move of the mounted suppressor. Sure, you could put two cans in the bag, but the takedown does not fit if one is attached. Or...

One can and two applications.

We dont have to thread lock the HUB interface to the can, but most manufacturers recommend to do that. So lets do that, the HUB adapter is thread locked to the can and is not field changeable.

Is there a HUB adapter that will accept a Piston and Spring adapter for tilt barrel semi-auto 9mm, and also accept a non-piston adapter / barrel mount for 30 cal? A Bonus would be to provide for some sort of QD interface, like a taper or interrupted thread.

There are mounting systems, like Griffin, that will work if I'm willing to not lock the HUB interface. The HUB to suppressor adapter can be changed to adapt to either piston or non-piston apps. It's time consuming to do that, and leaving the HUB unlocked is not a great solution.

Hi All,

Looking for a solid recommendation for a RDS/HWS/RMR offset. I am running a Trij 60mm Hunter thermal and need a close range option. If you have specific mounts/pics that'd be awesome. Thanks.

Looks like the next rifle is going to be a 6 Creedmoor instead of the 6.5 Creedmoor... Looking for some load details from you guys that are already running it...

Now I have to figure out what I'm going to do with all these loaded 6.5 Creedmoor factory loads I have sitting here... Maye time to start pulling bullets.

I have been looking at spuhr mounts and like the innovation but I am curious what the toughest mounts really are?
