Which would you build for a varmint/deer rifle and why? Can a rifle chambered in 243 be reamed out to the 6mm ackley improved?

It's all about the brass. .243AI wins.

Short action slamo dunk I'd go 243 Ack, long action I'd go 6/06. With a 14 twist for sure...grin

I had a .243 Win rechamered to a 6mm AI and it works fine. I agree with the others, however, that a .243 AI is the way to go.

Technically the 6mm AI will gain more powder space than the 243 due to the 243 having less taper and less capacity to start.

Then you seat your bullet so far in said case, in order to fit it into SA and mag constraints, that you loose the advantage, particularily with heavier bullets.

There is a pretty good write up of the 6mm AI on the 6mm benchrest site, including some reasons for choosing it over the 243 AI. Of course, not everyone will find those reasons valid.

You do have some nice stuff. I suspect that if you ever counted them all, you ran out of fingers and toes.

This short comment probably went over the heads of most, but being able to "kiss" the lands and use the magazine box are critical for extreme accuracy.

If you have a short action, then the 243 AI is the way to go. If you have a long action, then the 6AI is the way to go.

I have always used Rem 7/08 brass for the 243 AI, turn the necks at 7mm, then use the 7mm dia to create a false shoulder where you set the headspace for your 243 AI, never loose a case.

Just in case you think that Rem brass will not shoot tiny groups, you badly mistaken.

I never had a 6-06 or the AI version. I opted for the 257 Weatherby with zero freebore instead and the 6.5 Rem mag AI.

I hunted coyotes, chucks, crows, jack rabbits, never had to shoot more than 450 yards...I just liked to blow the hell out of them, then hang them up in a tree and do some bullet testing on them...if there was anything left.

Ya'll are hair splitting and the 6mm/244 AI will beat the 243 AI in case capacity every time...plus I've never had ANY problems getting x57 brass...OR 234/308. It's nothing but a matter of choice...be a man...make your own and screw the rest...(evil smile and LOL)

LUCK
