I think if I seen two 16 pointers together in one day at the same time i would forget what goes first down the barrel .
The sst by hornady will not go down any of my t/c with out a fight ,and really who need that problem,it that 452 diameter bullet.I would tell you to go out and get a pack of the noslers 451 dia: full partition and you will see the difference,I will bet you you don't even need a starter hammer to get them in the bore .
What you can also try that works for me was to change the plastic sabot @ go with the harvester sabot .I had tried the sst 300 grain bullet in 50 cal. drop into a harvester 54 cal red sabot ,and shot them in my t/c New Englander ,they seem to load excellent ,the problem was at the 50 yard target they shot great ,but at the 100 yard target the group stated o open a little to much ,I may try them again next year.
