22 Creedmoor Twist Rate

[Spadfa]

Hey all - would like to ask who is running 69gr - 77gr projectiles in a 22 Creedmoor? Am particularly interested in accuracy, twist rate, speed and barrel length from those who are in the know. I am getting ready to do a build to shoot projectiles of the above mentioned weight range. Any advice is much appreciated. Cheers

22 creedmoor

I know several folks including myself have been playing with the 22 creedmoor for a while now. Please keep this thread to actual reloading information, and if you can please post some round count, barrel life numbers are all over the place. Here is a brief summary of the cartridge. You need to...

Not quite the weights you asked about but I use a 8 twist for both 75 grain hornady and 80.5 Berger’s. The 80.5 Berger reminds me of the 140 hybrid, hard to get a easier bullet to load, amazing accuracy with everything I have tried with it

@jmw what velocity are you getting with the 80.5's <load data> and have you shot any game with them? I'm contemplating getting an 8 twist prefit for both of those bullets to put the whoop ass on coyotes.

We have killed yotes and deer with the 80.5 Berger’s, not really used the 75s, shot a few of them when the barrel was new, but started using the Berger’s and never looked back. Very effective. My daughter killed 2 deer with them last year both just over 400 yards, both good shot placement, the one went maybe 10 yards and the other about 30. Lungs were destroyed in both

I am using 41gr h4350, 3425 mv, the barrel is a 22” benchmark carbon with a 6.5 ultra nine. Sounds like a 22

Thanks for the info jmv. You obviously built the rifle with the purpose of hunting in mind, which is what I will be doing. I am wanting to build the barrel around the projectile (instead of picking a projectile to suit the barrel). Am leaning towards a 1 in 9 twist to suit the 69gr TMK. I already have a very nice 25-06 that shoots the 75 Vmax with deadly effect. Am aiming for a 24" barrel - due to the idiots in our government here in Australia, restricting the use of suppressors. Love the looks of your build - awesome.
