shot the 338 gr powerbelts again with 80 and 90 grains of blackhorn with winchester primers... no cleaning between shots ... 6 shots total...
much better loading as far as witness mark.... it never came back to witness mark from first shot.. but came back to same point each shot after the 2nd...

1 inch group at 50 a little left and 1" high from dead center
and 4 inch group at 100 about 10" high and left....

i couldnt get the hornady fpb in 350grns into my barrell at all.... damaged the copper jacket trying to get it started?????????
