More fun with 308 Win

I have been doing more testing and toying with 308.

I have been using Alpha small rifle primer brass and CCI 450 small rifle magnum primers.

Rifleis a Zermatt Origin with 20" PVA M24 profile 1:10 twist.

MDT ACC Chassis.

My goal was 3000ft lbs of energy at the muzzle. This was due to a conversation I had with a buddy who just came back from a Safari. The company had a 3000ft lbs, at the muzzle, requirement for any rifle used for plains game. He took a 300wsm.

Powders were Varget and Power Pro 2000mr.

These loads are above book max but showed no pressure signs. I annealed every other firing. I worked the book pressure loads up using annealed starline srp brass.

I forgot to get pictures of the varget loads.

#1- Averaged 2605fps and .30" 5 shot group (No pressure Signs)

#2- Averaged 2614fps and .65" 5 shot group (No Pressure Signs)

#3- Averaged 2627fps and .88" 5 shot group (Very faint ejector mark)

#4- Averaged 2635fps and .55" 5 shot group (Again faint ejector mark, easy bolt lift)

#5- Averaged 2644fps and .23" 5 shot group (Ejector mark and at the very top of the bolt lift it was mildly sticky at the very top)

Power Pro 2000mr was a little lacking in the velocity dept.

My max load of 46.6 grains topped out at 2635 but should have been faster. My thought is that I am not getting complete powder burn. I found some partially burnt kernals in the barrel
.
The 46 grain load was absurdly accurate and had an average velocity of 2615.

My 1moa sticker fell off the hole it was covering so I just shot at the hole.

AR Novice handguard question

Looking to replace the handguard in the image and not sure what I need. Will a new handguard come with everything I need to install/mount? Pretty sure I have all the tools needed I just don't understand how the handguard mounts to the upper based on what is in the image. I'm also having trouble removing the gas block., I've loosened the allen screws on the bottom but it only slides about a 1/4". Is there a specific handguard where the Pic rail on the upper mates with the pic rail on the handguard?

Accessories WTS used barrels chambered for Impact 737R (lots of them)

If you were wanting to test a caliber, have a practice barrel, fire form brass or have a hunting rifle for you/the kids-- I have tons of barrels (roughly 50) of varying calibers. All have muzzle threads.
6.5 Creed (26"), 6GT, 6BRA (28"), 6 Dasher (28"), 25x47 (26"). Most of these are cerakoted black. Most are Bartlein, but some of the newer ones are CRB. No other barrel brands. The countours are a mix of m24, mtu, and CRB comp. All the threads are perfect and all are chambered by Stuteville precision for an Impact.

These were my comp barrels (most/all of those will have 1 &/or 2 day match wins on them). There are a couple outliers that will have close to over 3k rounds on them. There will also be a couple that have less than 100 rounds on them. I would be lying if I said I kept notes on all of them and as such I won't be able to tell you which ones have how many. I'm not a magician with a borescope so while I'm sure someone could tell which is which I am not going to take the time to scrub each one to bare metal to determine the amount of fire cracking etc to estimate a round count. I don't run anything hot (creedmoors in the low 2600s, bras at 2800 etc).

None of these were taken off because accuracy degraded-- at a certain point it is simply safer to put on a new barrel than risk it at a match. Some of these (the really low round count ones) were projects or place holders. They weren't taken off because of a lack of accuracy, but a lack of time.

Anyway, if you're interested shoot me a message and I can get you pics of what you're interested in. To make things simple-- $200/ea shipped to the lower 48. Again, I want to be clear that these are all USED barrels with varying round counts.

Have a good day!

7Prc not grouping

good day. so i got a custom rifle built with a heller arms EV5 26 inch barrel in 7prc.
got about 40 rounds in it now. have tried 3 different types of ammo that i could lay my hands onto.
hornady precision hunter 175gr, hornady outfitter 160gr, and hornady eld match 180gr.

shot all 3 boxes twice now. hornady precision hunter grouping 1.09 or worse, hornady 160 outfitter grouping .689 or worse, hornady 180gr eld match 1.91 or worse 10 shot groups. any suggestions. the only thing is for sure is that the outfitter rounds dont always chamber. have 6 out of a box of 20 that would not chamber.
second pic is of the second day.

any suggestions would help!!
thanks

Firearms Thunderbeast TBAC .338 Ultra

TBAC .338 Ultra with Area419 adapter. $1,650 shipped/insured.

I’ve had this several years and put less than 50 combined rounds of .223 and 6.5 Grendel through it. I do not like recoil and don’t have access to long-range shooting locally, so have no plans for a large caliber rifle.

Might entertain trades for high end Binos, Sako/Tikka 6.5 Creedmoor + glass.

If you are in Louisiana and have good references, we might can get this in your hands sooner than later. PM me.
