RE: Hunting bullet for .243 Ackley...
That's going to be a tough decision to make. I'm sure you ordered the 1 in 8 for the specific reason to shoot the heavier bullets. I guess I'd start out with the 105's and see how they perform. We all know your gun will end up telling you what it likes the best.
I'm especially interested in how things work out for you. My new .243 AI is almost ready to be put down into the glass. Rem. 700 SA w/ 26" Lilja at 1 in 9. English walnut wood. Hardest piece of wood I've ever had.
Anyhow, I'm gonna be interested to hear how you are making out with it, and what you find. I intend to shoot around 85 gr. and up in mine, but we'll see. Will be watching for your findings.......
