Oh sorry...

Not that I'm aware of.

My buddy is running the 166g hammers at over 3000 fps in his 20 inch 300wsm.

any load data for this load? I'm doing load development on the CA Ridgeline FFT 300wsm 20"

Not 20" but mine is a mild load 62.5 h4350 seated over last drive band

Thanks

Update. For my 22" 300 WSM I have moved away from the Hammer bullets as I could not get any better than 1 MOA. I am now shooting the Federal terminal ascent factory bullets. So far good velocity and BC as well as great accuracy for a factory round. My gun also likes the 200 grain factory ELD-X. Getting over 2800 FOS out of both. I would love to hand load the terminal ascent if I could find the bullet heads rather than factory ammo.

Can a 1:9 twist rate shoot the 166gr Hammers efficiently in a 20" inch barrel for 300wsm? I'd like a 300wsm that can fire the 166gr Hammers and also 215gr ammo without buying multiple rifles.

A 10 would do what you're wanting, but specifically…yes, a 9 would work.

I am wanting this too. I am shooting the 166g in 10 twist but 26"

I am wanting a shorter barrel for suppressor with a faster twist

Thanks

I would suggest you shoot hammers in your rifle and confirm BC. I would not run ballistics off their published BC and assume you are good to go.

I run a 22" 1/9 Proof CF, shoot 162 Absolute Hammers over H4350 @ 3240. I can speed it up pretty easily but it shot awesome there with 0 pressure so I just left it alone.

Just finished load development on a 21" 300WSM running the Berger 205EH right at 3000 with RL26, ADG brass and Fed 215s. Well under 1 moa at 100 and I hope to stretch it out later this week.
