[Brianma65]

Made up a 15 rnds of 55 g Varmageddon with some Benchmark powder.
Results looked promising.

3 ,5 round groups at 100 yards.

23 g benchmark 1.09 MOA
24 g benchmark .547 MOA
25 g benchmark .817 MOA.

Something to work with anyway.

I didn’t chrony them yet.
I’ll run some through the chrony tomorrow.

Try 23.4gr... one hole groups for my BIL

55gr varmegedon
Hornady case
Seller bellot SR primer.
OAL to 2.262

Try increasing in .3gr increments and find the sweet spot

I was having good luck at 24.5, incidentally the same charge weight in IMR 4895 produced similar results. Although I didn’t chrony either load.

I’m going to do a bit more testing around the 24 g point.
But if I can keep it consistent at the 1/2 MOA point, I’ll be a happy camper.

I found 24.5gr hornady brass cci400 loaded to 2.6 worked best for my rifle. Dont have my notes on me but velocity i believe was around 3100. 24"barrel
