CB1 predictive accuracy is so good, most especially when going transonic that it's almost boring. Good luck with the 375 CT and tell us more on your setup.
I will be using it with a few different rifles. My 375 Cheytac. It is built on a Stiller TAC 408 action, Benchmark 1.250" no contour 1:10.5 twist barrel ,spiral fluted with Schuler brake, Jewel trigger, McRee chassis, Atlas Bi-pod, 20 MOA base, 40 MOA Barrett rings, Night Force 8x32x56 scope.
I will be running it with my 6.5 SAUM as well, it is built on a Remmington 700 LA, Benchmark 1:8 Twist, 24" barrell with Elite Iron Delta Suppressor, Jewel trigger, McRee Chassis, Atlas bi-pod, USO 3.2x17x44, Barrett rings.
6.5 Creedmoor (match gun) It is a LH Stiller TAC 30 AW action, 26" 1:8.5 twist Benchmark barrel, McRee Chassis, Atlas Bi-pod, USO 5x25x58 scope, Jewel Trigger, Ross Schuler Brake (or can from the SAUM)
Barrett model 99 50 BMG 29" fluted barrel. (currently wearing a borrowed NF scope, need to get some glass on there, haven't been shooting it much since I got the Cheytac up and running)
Vectronix Terrapin for a range finder and soon to be in conjunction with the Nomad and Coldbore, I really hope it is all that its cracked up to be, it will be a very valuable tool on hunting trips! Have you tried the AA battery conversion? I was thinking of carrying one of those with me when doing back country hunts.
