Freebore for .308?

[03machstock]

I have a free barrel cert I need to use and I’m thinking of doing a .308 as a trainer for the recoil and wind. I already have a .223 for cheap reps but it lacks recoil. What freebore would work good for 168 smk, 175 tmk, 185 juggernaut, and other popular bullets around those ranges? 1:10 twist, 24”, bolt action, aics bottom metal to mag feed, but I can get a sled to single feed if I had to. Might shoot an f t/r match with it for fun but I am by no means trying to have a competitive f class rig. Just want something that isn’t fussy.

Rather than picking three bullets I would settle on one in particular. The 175 SMK is by far the best middle ground. The mill spec M118 LR round with the 175 smk had a chamber reamer specially made for the 168 and 175 smk and it had .117” freebore.

You might take a good look at 169 and 177 SMK's, which you can use the same freebore you're looking for. I've been using them a lot in my .308 and found they're performing better than the 168 and 175 SMK's that I've used. . . even better than the 175 TMK's (IMHO). They're cost only a hair more and well worth it???
