Dave, can you believe how well a 22" barreled White can shoot??? I picked up a 504 Whitelightning a month back and I am amazed at that little rifles abiliy to shoot.

Question or thought... my 504 bore on the Umag is a smidge bigger than the 504 on the Whitelightning... a 504 Bull Shop will go right to the bottom in the umag with just the weight of the ram rod, yet the same bullet in the Lightning does require some push down the bore. So I am wondering does your Bison have a slightly tighter bore than the UMag?

Guess it really doesn't matter - I am going to send you some bullets to shoot but you do need a + sized 50 cal bore. When you get them if you would pop off a few, would like to know your results and/or thoughts...

Awesome shooting by the way...
