Just got done doing some load development for my Archimedes 6.5cm. So far I'm really liking the H4350 140gr eldm easy button, seems like everything I've tried likes 41.5-42gr. The group side is excusable since I didn't have my bipod or front rest with me and just used a pack. Speeds are from the magnetospeed v3. Started seeing pressure at 43gr. So going to load up some 42gr and do some seating depth testing.
Case and primer, please
Hornady and Federal match 210m.
I picked up some lapua brass for after I'm done with my Hornady brass, but so far it's holding in there. I don't anneal yet and most of these cases are on the 6th firing.

Thanks for posting that. 40 grains of H100V with Peterson cases and CCI 250's with 156 Bergers got me 2613FPS ES6, SD3 at 30F out of a 22" Barrett. Shot bugholes when cold. Groups opened up as the air/rifle heated up, might drop down to 39.8 or so. Loaded .005" off the lands, really long COAL of 3.00" (minor cratering of primer, spicy but not scary hot)
Getting back to reloading for 6.5cm and bolt action again. Found some fed 210 locally and picked up 1k. Tried to trade local but figure I can still use the lrp for 1k rds and get better at long range in the meantime, definitely will be in this thread a lot as i buy more components 
Several reloading questions.
I'm Currently using the old prime brass.. Imported. How many reloads are you getting approximately with safe loads with these cases? (I am still fine tuning the load as the barrel is just recently broken in. <140 Amax, 210, 41.8.0 H4350> is what I am currently shooting/tweaking.
When these cases go south I will try SPP Lapua brass.
When you made the switchfrom LRP to SRP brass, understanding each barrel and chamber is different, how much tweaking of your pet load was required ?
I'll likely switch to 140 ELDM's when my stock of Amaxes is used up, although last time I was at the range I shot a few Berger 130 VLDH test loads @ 1K and the results were promising there too.
Decisions, Decisions....

Hunting rounds yes, I don't really shoot match bullets
Had ok results from it. Biggest thing is powder compression. Leads to inconsistent seating depths.

I've had excellent results with 6.5staball under a Berger 130 at 2800 fps. The eldm 140 was "ok" but best I could do repeatedly was about .45" . The 130 bergers I am at .18" - 3 round group and .24" - 5 round group and can do so very regularly so I just gave up on running the 140 and stick with the 130s. If I need to get past 1350yds I can go out further with the eldm 140gr. Really don't need to shoot that far with 6.5cm anyway so.... I think the proof carbon prefit just doesn't like the heavier bullets ad well. Might do better with H4350 but there's not really a reason to for me and with powder so hard to come by and 6.5staball metering so well, kind of hard to find a reason to do anything else with it.
Staball is looking good since i cant find 4350 locally
load test on my buddy's 6.5 creedmoor cadex rifle today. 147gr eld match rounds, hornady brass, cci large rifle primers. h4350 powder. seated 20thou off the lands. found the perfect load. 41.4 grains. almost the same speed as my rpr with a IBI barrel.

Trued the axial form factor in 4DOF of my 140 ELDM load at 525 and 780 yards Thursday evening. First 3 shots at 780 were .1 mil below the waterline. Re-painted the target and the next four wer .1 mil high. Repainted, pulled my head out and made the correction I needed, fired 3 shots without holding any wind, and heard 3 impacts. Drove down to the target and thought I only saw one impact. Had 3 shots in 1.5". My rifle is ready for the NRL Hunter match next week, hopefully I am.
40.5 gr Rl16. Peterson brass, CCI450, .055" off the lands, 2844 fps, Sd of 4.

Congrats and nice shooting 
Staball 43.8, Barnes MB 140, Starline SRP 1x fired, CCI450, 2.82". 3 shots. Kept ammo in a cooler with a hot water bottle as it was mid 40s. A modest 2750fps. Have 10 more loaded up to see how they do.
I run that load in S&B brass. I got about 100 fps more velocity with S&B than Hornady brass.
New criterion 8twist 26inch 6.5creed.
had 51 rounds of old Horn Amax factory 140ammo. Ran it through barrel with a few cleaning cycles in between. Averaged bout mid .6
processed that hornady brass and tested following
Staball6.5
WLR primers
147eldm @ .020 off - this chambers freebore must be a lil short because this puts average OAL @ 2.858"
ran velocity ladder and found a flat spot from 44.2-44.4 ( 2761fps. )
Group and dope tested 44.3 w/ [email protected] off.
Group at 100 was bout high .3
dope out to 1007yds confirms velocity at 2760 using a G7 of .340?? ( will revisit this because its been quite windy this morning )
Im sure the barrel will speed up a lil bit over next hundred or so rounds... Im quite pleased w/ velocity as is though!
easy button / love it when it goes down this easy!!

newbie. Just set up reloading room. Where do you guys recommend purchasing powder and other reloading supplies ???
Wherever you can find it at this point. Powdervalley, midway, brownells, midsouth, graf. I also check with local shooters to see what they have and try to avoid hazmat
Hey guys, I haven't been on in a while, but I went back through the last couple of pages. But is anyone using Shooters World 4350? I grabbed 8 lbs recently and the only thing I've been able to find is that it's the slower of the 4350 powders. Anyone having good results with 140 ELDMs? I'll be using hornady brass and 210M primers.
22" Barrel
130 gr Berger Hunting VLD
42.0 gr H4350
REM 9 1/2 Mag primers
2.80" coal
REM 700 action with a factory barrel in a HS Precision Stock
Email alerts are your friend. Have tabs open on your phone/pc for the mentioned vendors and be ready to pounce.
Midway is starting to get more powders in stock. I check 3-5 times a day and find something I need once every week or so. I’ve picked up varget, IMR 4350, RL16 and retumbo in the last month. Powder valley has some now and then also.
Just started hand loading august of 2021 and I’m deep down the rabbit hole at this point. Recently picked up a Daniel Defense Delta 5 at the recommendation of a friend.
Have 250 rounds through it so far. More on the gun later. Here’s the load I’ve found it likes:
Lapua SRP Brass
CCI 400 primers
40gn IMR 4350
142gn Sierra Match King
2.277 BTO
Got a personal best 5 shot SD (1) and ES (3) with this load cruising at 2600fps at 550’ elev and get groups consistently around .3 moa ..a little on the slow side, but I’m after accuracy for this rifle.
Took it out to 515 yards last weekend and got a ~.45 moa group with ~8mph wind (my second time ever shooting past 200yards so I’m still learning the wind thing). The impressive thing to me was the < 1 inch of vertical in the group.
Daniel Defense guarantees a .75 moa on this gun and through load development I’ve seen very few 5 round groups larger than .75 moa. It seems to be an accurate barrel.
The gun itself is nice, but for the price I have a couple of disappointments. The stock is flimsy. I have a KRG on another rifle and this thing isn’t even close. You can twist the front of the stock and bend it up to touch the barrel. Stiffer would be better. My other complaint is the action. The bolt is not smooth at all. Nothing like you’d expect from a $1800 gun. My stock Remington 700 feels like glass compared to this thing.
Overall, I like the gun and I do enjoy shooting it, but will probably swap the stock if I end up keeping the rifle long term. The action does make me want to try other models, however. I have a Christensen Arms BA tactical in 6.5cm on order and have higher expectations for it on fit and finish. Will post my loads developed with it and thoughts on it once it comes in and I have some rounds down range.

How many rounds do you guys typically go through when loading up to find charge weight, grouping, neck tension, seating depth etc. etc. ?
Typically you do the .5gr increments or go down to .2? I just picked up an 8lb'er of staball and have read the threads that it likes to be at or just a hair over book max. Going to be shot out of a 20"tikka ctr and i know they typically run slower
Does anyone have any info on 156 eols in their 6.5creedmoor? Trying to figure out the jump and get it up to 2600fps in my 20" barrel to stabilize better. Jumping 0.070 off right now and the 200 yards groups were not good(40.8gr-41.4gr). The charge ladder work up were touching almost every shot at 100 yards.
Tikka ctr 20" suppressed
h4350
Lapua lrp
fed 210m
Since I am limited by my mag i ran then as long as i could with an OAL of 2.944. Thinking about jumping 0.100-0.120. Which would put me at 2.914-2.894. If anyone has ran these and has some info I am all ears. 41.4grains averaged 2577fps. Haven't seen any pressure yet but I was shooting at like 26 degrees

Being a 300wm fan myself, I understand wanting to throw the weight, but 156 may be a little much for that gun. Check the “stability factor” on the applied ballistics app. You want to make sure it’s 1.5 or higher.
I totally understand and I did check it I am at 1.46 being at 2577fps and I am still loading up i expect to get to 2600. which would put me at 1.5 or 1.6. Trust me id much rather tune loads for my 300 but it is already tuned. Just having fun shooting targets and working up loads. Got a box of 156's and figured why not. The factory stuff shot really well at 700. Haven't tried it out further yet.
I forget how much the temp & elevation factor. I bought some 153.5s to try but changed my mind after looking at the stability score. I’m at ~550ft w/ highs in the 60s right now, but I might could pull off something heavy like that in the Texas heat this summer.
I like your style. Send it!
Factory stuff shot really well for me too - in an 8 twist 20” Bartlein at around 800’ elevation.
What is everyone using for a reloading the 6.5 and is anyone using the Dillon presses? Thank you in advance!
Brass prep for sure on my 650. Most likely will bust out the rock chucker for priming, charging, and seating
I have the Forster Co-ax. Really like it.
This combo is shooting great for me but I have had to true out the G7 of the 147eld to .305 to get it to work out with real trajectories.
Did this with JBM & AppliedBallistics and both jived to within .005 G7.
Speed been verified with 2 different magneto speed units.
I have accounted for temp variance with the staball6.5 powder at .6fps per degree.
The barrel twist measures out to be about 8.2 / not enough loss of BC to account for real world results..
Not concerned bout it . Its doing what it needs to do for the now!
Once barrel has bout 150 rds on it Im going to develop on a different bullet anyway.. Just thought the data might be useful to someone.
Got about 500 rounds worth of staball6.5 down range so far in 2 different chamberings. From 19 degrees F to 76 degrees F over last couple months it's definitely doing very close to .6 fps per degree.
On the 147 ?? Have no clue. But it definitely dopes out at MV of 2760, G7 of 305 at 455, 605, 747, 904 & 1007 yds. On 3 different outings across 50 or so rounds down range.... IDK

Weird "crazy" high ES...
I have recently started loading for 6.5 Creedmore, been getting some high ES numbers ~50. On my 6GT load, using the same equipment and technique I am usually around 8-12 ES.
Here is what I got:
Alpha Brass
H4350 and CCI 450
140gr and 147gr ELDM
20 thou off the lands
~3 thou Neck Tension
The 50 ES was one a ladder test.
Here is one new thing I am trying, Neolube N2, could this be the cause?!

What he said. 550, is easy to use and very versatile. 650/750 for high production. A 650/750 without a case feeder is like supper without food.
Shot my first 6 5cm loads today.
Pretty happy with the results.
I wasn't able to get to my regular reloading equipment, so I used my backup stuff.
My impromptu setup was a Lee hand press, old gem pro 20 scale, Lee PPM, Franklin trickler and a Lee die set with their collet neck sizer, of which I polished the mandrel in my drill stepping up to 5000g sand paper and light oil. It looks like a mirror.
I settled on
41.5gr H4350
Cci450 primers
140gr Eldm
Lapua virgin brass
I lightly lubed the inside of each neck with imperial wax and collet sized.
Cleaned the wax out with 99%iso and a qtip. Everything went smoothly.
Pretty happy with the groups.
Thought some of you may get a kick out of the minimal setup and results.
Btw, the targets with the large diamonds were not printed to scale. The 1 moa squares are more like .85moa
Top left target 10rds. All other groups 5rds

Lil lee hand press was my first press, its slept on for a low key, travel, on the spot type press
Are you saying the 50 ES was from different loads?
