300 wsm 215 berger

[TexSavage]

I am using 67 grains H4381SC, CCI primer (going back to Federal 215M though), Berger 215, Savage 12BVSS 26" 1:10RH, using Nosler brass and getting 2790 fps, 7ES. Shoots .35 MOA at 550 & 600 yards.
THIS IS A MAX LOAD WORK UP TO IT. IT MAY NOT WORK IN YOUR RIFLE.

No, all med or long.

Would the medium action be a Winchester M70? I'm pondering the idea of a pushfeed M70 in 300 wsm.

I will be delving into this same setup, I have a Tikka getting a 23" hells canyon summit barrel chambered in 300wsm cut with 225 freebore 1:9 twist, all the titanium goodies I could find, bedding into a Mesa altitude stock. Also had a guy weight sort 100pcs Bertram brass within 2gr spread. The rifle should be done this winter. I'll be using rl26. If I can get 2850fps and accuracy I'll be very happy, this rifle should tip the scale around 6.2# or so when complete, be around 8# in the field. Will be used for mountain hunts where shots could go from 25y to as far I'm comfortable with the rifle.

For those using reloader 26 what powder charge are you using ?

On my long actioned 300wsm with a OAL of 3.194" I use 69grs of R-26 for 2960fps. I just built a 20" on a highly modified sa with a OAL of 3.135" and I got 2762fps with 68.5grs but the barrel hasn't sped up yet. The 26" barrel ran right about 2900-2910 prior to speeding up and settled at 2960fps after. This is with CCI 250's and Winchester brass. The 20" barreled gun shot this group on Monday during the middle of the day with heavy mirage and shifting winds @ 536yds. That was also with a TBAC Ultra 9 suppressor.

Reloader 26 under a 215 is shooting exceptional, I've done a few at 24 inches and they are running 2900 fps, the node is so good no one has tried to see if the next one is reachable.

Do you think a guy can run these without a brake and still spot hits?

 

[IdahoCTD]

I will answer that and Rhian can chime in as well. No you wouldn't be able to spot shots with a hunting weight rifle. I just built one with a 20" barrel and Ultra 9 can that weighs 9lbs 1oz with the scope and it's no where near able to spot shots with 10oz hanging on the end of the barrel. I was pretty disappointing in the lack of recoil reduction offered by the can. In comparison my 9lb 300wm with a carbon barrel shooting 8grs more powder is pretty easy to spot shots with using one of my 5 port Ti Beast brakes.

Are y'all using magnum primers with rl26? I have federal 210m and 215 m

You might try h4350 too that's what I've been running behind the 215s for several years.

Any know-how on how much velocity loss from RL26 to H4350

 

[Kelly1278]

Im not sure but i got 100 fps more with my 6.5 creedmoor

You got 100 more fps w/ H4350 vs RL26? Equal pressure and 140+ gr bullet? Something smells funny.......

 

[Kelly1278]

Maybe I didn't push the 4350 hard enough but there is a thread on here about people's results with the creedmoor and 26

We're thinking same thing, rl26 gets more velocity than 4350, **** internet......
