No probley not but thats the fun of reloading for me soaking everybit out of a round. I bet the old core locs bc isn't that high.I have to go try these babys on paper at500 yards and see whatthey do compared to the accubonds what do you guys think. Im pretty new on this reloading deal but man its great Im never bored now. I just wish for it to warm up again.
