Well I'm pushing the old 160 gr. Seer two core Grand Slams at 2910 FPS from my .280 Rem. 1909 Argie. Brass is Winchester nickel plated, WLR primer and powder the now long discontinued Winchester WMR. I have a good supply of that powder. Accuracy runs in the .75" range on average. It just might be the rifle I take for my elk hunt this year.

Our forefathers did not politely protest the British.They did not vote them out of office, nor did they impeach the king,march on the capitol or ask permission for their rights. ----------------They just shot them.
