  2. These work on other .458 diameter projectiles 5 Star Review

    Posted by on Apr 10th 2018

    I purchased a .450 BM plus mold. I won't cast until late May. I live in Canada and it's not good casting weather. What I did find with these gas checks is they fit on my other .458
    cast projectiles they fit Tight and don't spin on the shank a good solid bond. They are .125 height so bearing surface to rifling is increased. I did not find one check laying in the snow. They hold on . I tested moderate range loads and full power hunting loads. Accuracy is just as good as with any copper that's out there. If you own a 4570 450 marlin
    458 Win Mag 450 BM or any other .458 give these a try . You will not be disappointed . I didn't dig any projectiles out of the bank as I have better things to do than than dig in the hard frozen bank.
    This is my 50th anniversary for reloading and casting. I could write a book on my experiences. Good luck any enjoy our sport.
