I just wonder if either of those setup with a little freebore and faster twist would shoot well? ….especially th3 270 WSM? I’m thinking OAL near 3.15” or something like that.

I’m running my 270WSM OAL @ 2.980 using 150 ABLR @ .20 off lands for 3120 FPS. I believe the barrels freeborn is .80 longer. I could never freeborn as long as you want for mag length. The bullet junction at the base of the neck is perfect already

Good info…so the 150 ABLR is in a good location with the shorter OAL…26” barrel?

300wsm 200 freebore, 215 Hyb @ 3.188 coal touching lands. 23" barrel. With 67.5 rl26 2870 is where I'm running mine. Can't wait for ADG brass, as this norma is super soft.
