Got a bartlein 1-7.7 twist on the way in Remington varmint with a trigger tech special and gonna have the smith true up the rem 700 action. Curious on bullet selection I was thinking 75-80 grainers in Sierra or Hornady. Gonna be using lapua brass with Varget or h4895 and pointers would be appreciated and what are the thoughts on grayboe stocks?
 
We've got a 223 ai at the shop that LOVES a case full of varget & 75 ELDM. Itty bitty groups, sounds like you've got the right components for a tack driver!

We've had alot of experience with manners, mcmillan and mesa. Never have ran a grayboe though.

Had no idea you guys had a website! Good to know! what are your thoughts on mesa vs McMillan. I definitely like the look of the mesa just don't know anyone who's used one in my area
 
Have it reamed with .100-.120 freebore for versatility with heavier, longer projectiles. If you like to experiment with heavier bullets you'll be glad you did.

Same here. I used Lapua brass, Varget Powder, CCI 450s, and Hornady bullets. 80gn factory seconds to form the brass, and have 2k 75gn ELD-Ms ready to go next. Shoots lights out, easy to work with, and a ton of fun.

Weight on this rifle wasn't a concern so I put mine into a Foundation stock, got it bedded and everything. Walked it right out to 1400 yards with FF loads

Agreed - our Ai reamer has a short throat, seat the heavies and have your smith throat it to that length. You'll be glad you did. Bonus velocity and no compressed loads.
 
I kept mine shorter throated and set off a 75gn at AICS mag-length. Hawkins M5 DBM and Magpul 10-round mags, runs and feeds very easily.

I wasn't looking for any particular velocity, just a boring 3000+ round barrel life for plinking steel. If I had a BDL bottom metal I probably would have throated longer. If you don't want to feed through a short mag like I did, get the longer throat and the free speed for sure though.
 
I'm using a longer throat 26" 1/8tw, and using 2520 powder, I am easily hitting 3,100fps with 75's and 3,000fps with the 80's. The 5 shot groups are in the 2's with the occasional sub 2's.
