Again, 22" barrel, 135 Berger LRHT, shot # 115 from the barrel. This was max. First slight signs of pressure. I have backed it down to 3230fps.

I love the look of Ackley shoulders with bullets sticking way out…..but I also like reasonably priced die sets!

So, that makes me think I should be looking at a 270 Win, 6 Creedmoor, 6.5 Creedmoor, 25-06AI, or ……for a next 473 bolt face barrel chambering. I'd like to go way below 300, run fast twist barrel and high bc bullets.

I'm thinking 6 or 25 cal honestly.

So, what can I get does for?

What real benefit am I getting choosing AI or Sherman calibers?

Trade off for performance is generally dipping into a more niche group of cartridges. If you wanna be able to buy a $50 set at the local shop, you're gonna be looking at mainstream stuff. It'll work but if you want every ounce of performance then going to one of the others is where you'll find it. A used set of dies can be had reasonable if you look. $100 Bill can generally do it.

I got the 87 Vax bullets to turn into gray smoke from a 8 twist 6mm06 at over 3500. I was trying for the 6mm AI thing without brass avail problems & fire forming. I used a .243 F/L dies to neck down .270 Win brass & 6.5-06 F/L die as a body die - real cheap but worked good. Trimmed & turned. Real barrel burner not good for lotz of shots.

Depends on the bullet too.

A 6mm 85 VMax in a 1:7" will vPorize about 3650fps...

And we know this because.....?

I was doing an OCW test @ 200.
The groups had started to open up drastically the last load.
First shot, I saw a perpendicular 10' line of dust appear about 20' from the bench, and could not find the hole on the target. I figured what had happened, so I kept my left eye open and concentrated on that area for the next shot. Saw a rainbow halo appear about 20' out and the same line of dust appear left to right of the bullet path.

I giggled like a little girl.

I powdered off my first bullets in 1958-9. A 220 Swift shooting bullets designed for a 22 Hornet. But what would one expect from a teenager.

A video of that would have been golden.
