Got around to trying my CZ 375 H&H with CBs after previously firing 50 full powered J word reloads to fireform my brass (ouch!). Lyman 375449 FNGC, sized .377, weighing 283 grains, lube grooves smeared with JPW, seated out so as to not go below the case neck-2.57" OAL. CCI large rifle primers and 1.5 grains of polyester fiber. 33 grains of H4198 gave an average of 1693 fps, while 34 grains gave 1728 fps. Recoil in the heavy rifle was about the same as a 180 grain .308. Accuracy at 50 yards kept all the bullets holes touching (with the rifles iron sights), and to my surprise the point of impact was the same as the full power loads I had fired. The rifle showed no signs of leading after 50 rounds. All in all a very rewarding experience. Now on to my Ruger No 1 in 45-70.:-D
