1:8 twist .22br powder choice.

[andybrock]

I’ve got a .22br with a 1:8 barrel that I had built for shooting 75gr amax. I’ve moved away from the amax and want to use 55gr sbk’s in this rifle. With it being a fast twist barrel would a slower powder work best with the 55’s? I’ve got n133, n135 and varget.
I’m thinking the n133 would be too fast?
Thanks

If it will shoot in your rifle, Varget would be my first choice. Good luck!

Not meaning to hi-jack this thread but I live in N.Illinois (alt. 750’) and have a 7.5” twist to shoot the 85.5grn. Powder choices are not a problem. Suggestions? PM me your choice.

I’m pretty sure this powder isn’t available anymore in my part of the world.

I own two .22 BR rifles with 8 twist barrels. I call them .22 Bart and .22 Brux. I have found, after several thousand rounds that the 70 Berger VLD Tangent and 73 Berger Secant, will outshoot the 77 TMK, 80 MK, 80 Bergers, 80 Custom Competition. I have experience with 75 gr bullets, shooting several hundred 75 Partizans, and 200 75 A-Max. I shoot VV N-140 the most with the 70s and 73. My second choice would be Varget. AR-Comp, H-4895 and N-135 are also very accurate in the .22 BR with long bullets. I have shot 32.5gr Varget with 55gr Ballistic Tips and got 3546 fps. I featured that load on one ground squirrel trip.
