My saum feeds very smooth. What action did you put your saum on. I know you said adl but was it a regular action opened up for mags or was it a wsm action to begin with. There are a few tricks to get the 700 to feed fatties.

Yes it was 222 action to start. I may just have the stock opened up to BDL and go to a centerfeed Wyatt box.

Talking with @GLTaylor about building a 264 cal that would be beltless in the 70-80 grains of powder capacity. Need to have good quality and available brass. Thoughts?
Questions questions runnning through my mind.

Sounds like a barrel burner. Getting the correct twist rate sounds like a challange as the speeds could possibly strip the peojectile or cause tumbling I would think. Have you found a projectile?

High quality brass. Maybe Norma? Gee mate. Im still stuck on the case compacity for a 264😦


Oh. You own Hammer Bullets😅

Plenty of online tools to assist with calculating twist rates.

Custom barrels are readily ordered in most twist rates.

Increased twist rates don't harm bullets (mono's), as an example the 6.5, 124 Hammer Hunter is stable in a 1-8" twist, I'm shooting it a 1-6" twist without issues. Other examples up and down the line to support this.

I'm currently shooting the 124 Hammer Hunter at 3960 fps, without seeing the effects you're curious about.

Barrel life is relative, and should be qualified by purpose. A rifle intended to competitively shoot 10 round groups, or a volume oriented varmint rifle with 500-1000 round days, will suffer long before a big game rifle is no longer useable.

7 blaser mag, necked to 6.5 with a 35° shoulder and reduced taper. Basically a stretched wsm/shortened nosler. 85 gr capacity. Would run a lil faster than a 264wm, with a long neck and way less trimming. Plus the case is only 2.34" long.

You’ll need a very slow burning powder you can’t find right now, a bonded , high ballistic coefficient bullet that holds together at close range yet expands reliably at lower velocities, readily available brass and better put creedmoor in the name somewhere or it will never work! Lmao!
it’ll work...it just won’t be “tacticool”
