Nice!! Looks like your .223 rig would also work well for F-T/R. I really like the 'no recoil' of a .223. I recently built a single-shot R700 (40-X) in .223 with a Bartlein 5R barrel for F-T/R

However, BPCR & BPTR (200yd to 1000yd) are my first loves (along with sporting clays in the winter), so not sure how many times I'll get out to the F-Class matches. We have a 600yd range at my home range (~20min from the house) and Bridgeville, DE has 1000yd. Have another three 600yd ranges within 2hr, so plenty of places to shoot. The upside is the barrel will last a long time if I don't shoot it.
I'm just getting started on a ladder-test for the rifle and have both the tipped and traditional 77gr SMK, 80gr A-Max & SMK, 80gr, 80.5gr, 82gr & 90gr Berger to test. Berger's generally fly best for me, but one never knows until they do the test. Had the chamber cut for 80gr & 90gr bullets for 800yd+, but the 77s may do what's needed at 600yd. Wanted to get out in our record 73F temps today but it was so windy it would have been a waste of ammo.
