A 7 or 8 twist barrel, screw the 9 twist.

Why?  I've got a RRA 20" 1:9.  Want to know the heaviest bullet for long distance shooting?

Your 9 twist will easily handle the 69's and most will also shoot the 77MK's, 77 Nosler CC and Hornady 75's.
 You will get people that don't actually shoot heavies decrying the 9 twist.

I really have never had any luck. I have shot a lot of rifles with 1:9 and never been able to get those heavy bullets to shoot. Well sure they shoot but nothing like the lighter bullets do in the 1:9. I have ran them from 16"-24" and not had any luck.

You think I could get them out to 300 yards?

300 yards , yes, easy.
We shoot out to 600 with 18" 9 twist 5.56 AR 15's using 77 MK's over 23.5 Ramshot TAC.
You can use the 77Nosler CC's or 75 Hornady with the same powder charge.
Carp, are you using the 69's? They shold spin up easy in the 9.
Very surprising if you can't get a true 9 twist to shoot the 69's. Most will shoot the 77's as well.

Yes I run a lot of sierra's in all my 22 cal guns. I have tried the the 69 77 and 80 all in the hpbt match flavor. 1:8 was night and day difference in my groups. Ran the loads threw several guns as I have shot them threw 1:9's 1:8's and 1:7's. I just have not seen a 69 load that shot good enough to match the 1:8's :dunno:

Is it going to be a coyote gun or for the end of the world?  Answer will dictate suggestions.

Not really, I got a .25 wssm for that.

It will be mainly a plinking gun, but I might take it for yote.

I know the feeling. I've been waiting almost 5 months for my Alexander Arms complete upper in 6.5 Grendal. :(
