I have not seen anyone try N570, but here's the load I settled on as a mild load in my rifle for barrel break in. Your results may vary.

24" benchmark barrel 7.5 twist chambered by Blue Mountain Precision
131 Blackjack
Hornady Gap 4S Brass
63.3 N570
Fed 215M
2.23 CBTO
barrel has been speeding up but I think after 50 rounds it's starting to stabilize.

last 10 shots
velocity 3195
ES 49
sd 15.8

I know it's not a great tripod, it’s for my camera. Just trying out shooting clipped in.

Anybody get an AMP code for ADG 25SAUM (6.5SAUM) brass yet? I burned one after second firing on the brass and got 0147. Seems low…

 

[Len901]

My ADG brass with 6.5 saum is 0145

Finalized load development for my 25SAUM this weekend after just passing 180rds on the 21”barrel.

N565/6.5 SAUM ADG/CCI200/.282 SAC
60grs makes 3005fps and single digit es. Pictured is a 4 shot group with the last of my 134s. Time to order 1000 of the same lot number

OMR

Awesome been thinking about getting that or one-off of ja outdoors I have the same omr bolt shroud. In your load development is that load in the high node meaning near pressure

 

[Len901]

Did you end up trying the 133 or 135s

I got to 3040ish and the groups started opening up. Never saw pressure with the 134.

Yeah I tested the 128, 133, 134 and 135. Everything shot under an inch pretty consistently except for the 128. The 134’s shot the best by far
