Can anyone tell me where I can get 395 - 400 grain .475 cal. hard cast gas check as in LFNGC Bullets from? I 've tried CPB and Beartooth Bullets but they only offer a lighter or heavier bullet. I don't have enough front sight for the heavies and I didn't want to go any lighter. I'm using a .410 gr WFNGC from CPB but wanted a LFNGC. I used to be able to get just what I wanted from Montana Bullets but they are now, sadly, are out of business. Thanks.
