Tried 3 rounds from my MRC for my first test today at 100yds. Swift 300gr A-Frame 375 H&H factory load. Was trying to use a Magnetospeed chronograph while doing it, but with my muzzle brake it wouldn’t record. If it keeps this up, I think they did a good enough load in their factory loads.
Having the muzzlebrake removed to see how I can handle it. The recoil doesn’t concern me, but loading another round and getting back on the target is my concern. I’ve fired a Ruger in 416 Rigby, 338 Lapua and a CZ in 458 Lott without a problem with recoil, but it just took me forever to reload and get back on target!

If it'll repeat, no need to look further.
 
My 375 doesn't have a break and I can recover quickly. Far quicker that I can my 416 Rem with a muzzle brake.
 
Those shots will cut all the meat you want sir!
 
Hmmm...removed the muzzlebrake and went back to see how it would do. POI with the 300 A-frames dropped 5”! Never thought that heavy of a barrel would be changing harmonics that much!
Other results testing the Swift 300, NorthFork 300 SS and even my 1/2” consistently grouping 250 Barnes TTSX, all groups opened up and POI changed. Rather than starting all over on my loads, I think I’ll just put the brake back on until after my May hunt. At that point, I may or may not start over on my hand loads.
