New 111 XP 300 Win Mag with Bushy Scope, a few questions.

Wanted, a 338 Lapua 111 LRH but after researching bullet cost and some minor issues I deiced on a 111 XP in 300 mag, comes with the scope which I will sell immediately, will sell the barre; immediately.

Wondering what the diff between the 110 and the 111 is ? Barrel thickness or is the action different?

Planning to put a Criterion barrel on it, will be using for extreme range shooting, 1000+ meters from prone and bench, what contour and twist is best (guessing 1-10) for heavier bullets.

I just got a Mccrees stock for my 308 10 FP, have not had a chance to mount and shoot it yetbut it look great. Wondering what stock the learned suggest for this caliber?

Notes on the 111 XP, has a nice-ish jeweled bolt, not as nice as my winny M 70 jeweling but nicer than the black powder coat on my other Savages.

I just picked up an XLR chassis for my 300 WM build. I also have owned all the choates and like those for being on a budget. This will be my first experience with an aluminum chassis, it should be here today.

went with the choat tactical will get CDI bottom metal.
