It was finally warm enough outside to get out to the range and try the muzzle brake. Not that I expected anything else, but with full power rifle loads ( 375 Winchester ) there was only aprox. 1 1/2" of climb Very happy to say the least.Made and installed a replacement muzzle brake on a 375 Winchester 14" contender barrel. The brake itself is made from forged 4140 steel ( heavy truck air brake camshaft ) Then blackened with Caswells black oxide kit. The flash really seems to cut thru the black oxide as it is much nicer in person! The end of the BBL. is threaded 11/16-24 tpi ( not out of convenience ) it left me extra "meat" on the outside chance something went south!!! An were forced to re cut and thread to the next smaller size. Please escuse the dog hair that appear as a scratch or two! And to answer the next question, it isn't as heavy and bulky as it appears! Now I just wish it wasn't 40 below 0 with the wind today! I would like to get out and fire it a few times to see how it works! Happy new year all!
