You load looks about right for a .223AI, but I think you should try BLC2. This is a nice dense loading, and should group very well (start at 26.5 grains)

I have not tried the BLC2, your the 3rd person who has brought it up, might be something to that. It's a 300 yard zero, and 1.5 mil hold over to a 500 yard kill provided I do the rest.

Can't wait to get my hands on some of the new 53gr v-max's. .290 of BC...that's crazy!

you also might want to try H335 and H322. I've had some luck with the older lots of 2015BR as well as IMR 3031. I know where a .222AI reamer resides, and have been thinking for a few years now about building a long necked .223AI off of that reamer using a 1:8 twist barrel. The longer neck will handle 70 grain bullets better than the standard .223 neck, and case capacity looks similar to a generic .223. If it won't shoot; I'll simply build a fast twist 22-250 out of it (actually a 22-250 short)

Re: .223 vs .223AI

That's promising to hear. So, if I had no plans to ever shoot anything heavier than a 60grainer's what twist should I use? I guessing 1-12 should be about perfect.

Thoughts?????

Re: .223 vs .223AI

Was just looking on Broughton's site and they make a 1-13 5C That just may be what I'm looking for.

What do you all think for length? I can't decide between 24 and 26.

I would go with a 26. Mine is a 24 w/break wish I had done a 26.... Oh well.

I've tried 60 grain bullets in a .223 (1:14 twist) and a 1:12 twist 22-250. The 60 was getting ragged in the 22-250, and similar results with the .223. Three quarter inch groups were the norm. I think a 1:10 twist would be perfect in the 22-250, but on the otherhand I never really did a lot of development with the 60 grain bullet so there might be a problem. Perhaps a shorter 60 grain bullets is what I needed.

Fifty-five grain Nosler BT's bullets have problems in a 22-250 with a 1:14 twist, but the Vmax shoots just fine due to the S/G factor. But the Nosler shoots fine in a 1:12 twist. The 60 grain partition bullets will shoot OK in a 1:12 twist 22-250, but will be almost unstable in a 1:14. I've been messing around with 60 grain Hornadays, and can say for sure they won't work in a 1:14 twist barrel. But a 1:10 (or even a 1:11) barrel should put you right in there. Savage has offered a 1:9 twist 22-250 barrel in the past, and would think it would handle anything out to 75 grains
