Did you get a 450BM? If not, my recommendation is a CVA Cascade. My first of four Cascades was the 450 and I liked it so much I bought 3 more in 308, 350 Legend, and 300 BO.Agree that meat damage is extensive w/ 450 Bushmaster on deer w/ supersonic loads. With subsonic (which is what I plan to use) damage will be similar to that of 44 mag. With a Hornady 395 grain bullet leaving the muzzle at 1050 fps (976 ft-lbs) at 200 yds the velocity will be 920 fps & energy 742 ft-lbs. Although not at the 1000 ft-lbs. threshold often used for min energy to harvest game, this is on a 45 cal bullet which starts as a big hole & should expand some.
Mine is sub MOA with jacketed bullet reloads.
This wasn’t a “whoopee, look at the new cartridge I need to buy that I can shoot out of an AR-15” purchase. I really wanted a 44 Magnum rifle and after getting rid of a Marlin 1894 that I couldn’t get to shoot accurately (with anything), I settled on the Cascade in 450BM. It will shoot substantially harder than the 44mag but I shoot mostly cast bullets in the 44mag velocity range. So, it’s the rifle I wanted in a different caliber…
The only thing I didn’t like about it is the small primer pockets but have since attained some empties with large primers. Pretty sure I’ll get better ignition with the slower powders and should be able to use smaller charges but getting the same velocities. Some testing is in order…
