Re: .243AI Light Versus Heavy Bullets?

In the 1-8 twist those 115gr bullets are very iffy; especially in the shorter 26" barrel...
just my findings in my .24 cal rifles... You might be better served using a 1-7 or 1.6.5 twist for those heaver ones.
Just my .02

    David Tubb mentioned that 1:8 wasn't fast enough for him with his 115 DTAC. I believe he's now using 1:7.5 or maybe even 1:7.?

    Yeah, David I'm sure is correct, he gives great council.... however I think most of David's thinking on this; is around 30" inch barrels. I believe {with that said; I can't speak for David obviously} I think when you go to a shorter barrel as you mentioned you might what to even think about the 1-6.5" twist as well. I've had a few barrel in 1-8 as well as 1-7 twist {after talking with David} that got a little long in the tooth... and were set back and cut back to 24" and 26" inch barrels; for Coyote hunting. They seem to have a tough time stabilizing the 115gr and heavier. You may want to also think about Tubb's 111gr bullet... this seems to be a very fine bullet.
    Good luck
