New Contest Starting Now! This Target Haunts Me
Tell us about the one that got away, the flier that ruined your group, the zero that drifted, the shot you still see when you close your eyes. Winner will receive a free scope!
Too deep is more of a pistol concern. Generally, too long is the rifle concern. Contacting the lands tends to lead to pressure spikes.
If you’re getting hard bolt lift, 88 grains of Retumbo with a 300 grain bullet is borderline in your rifle.
I got a chance to shoot another rifle and three different loads. I get the occasional sub-moa load, but most groups average between 1.25-1.5 moa. The PSA is a lot of performance for the money.
Is there a thread where people show the types of groups they are getting with gun and ammo/load information? If not, there should be.
Please post them.
I was able to compare a couple loads in a couple uppers with different barrel lengths.
20” Odin Works barrel
Avg: 2474; sd: 14.9
Load1: 30.2 CFE 223 and 100 ELD-VT
Avg: 2403; sd: 17.2
Load2: 27.0 AR Comp and 123 SMK
24” Lilja barrel
Avg: 2526; sd: 23.4
Load1: 30.2 CFE 223 and 100 ELD-VT...
These bullets have been out a while. Hopefully some guys here can share the loads the have worked well.
Bolt/Gas
Cartridge
Powder
Charge
Velocity
ES/SD
All of the usual guidelines apply. Every gun is different. Start low, and work up. Et cetera.
Thanks in advance.
@45-90,
I see the one recipe. Can you share some more data and groups? Are you using any special upgrades to your 308? That’s pretty incredible performance.
This is a great thread.
