We got the .50 hushpuppy completed. we are surpassing both 500 s&w and .500 beowulf balistics in a 17" barrel. it is on a short action M70. I am currently making a custom floor plate that will allow it to take ar-15 mags with the 500gr cast and the 500 and 300 gr woodleighs. the 650gr api will just have to be fired single shot but its worth it! at 100 yards all the above loads were moa and very close to the same poi. as soon as i get it to take ar mags ill post the pics.
300 gr bullet @ 2300
500gr i just load with 14gr of trail boss at 1050fps for when i get the form 1 back.
650gr api at 1400fps.
once again a 17" barrel.
this makes me happy..............
