Presently I am looking for a monolithic bullet for black bear hunting. There are a number of .429 caliber bullets on the market, however many are for pistol cartridges. This is not what I am looking for. I have seen the Hammer 200gr Stone Hammer and the 205gr Jack Hammer bullets, curious if there are any other manufacturers who make "rifle" bullets for the .444 cartridge. And of course these bullets have to be tube-fed compatible. Thanks for any input.
