Don, I've been hunting the "Scotia Barrens" here in Centre County with a NEF 45/70 for 14 years now, and have found out that those 300 grain JHP's shouldn't go much over 1800 fps for close range shooting or you end up with a lot of bloodshot meat. The factorystuff actually clocks(or used to) around 1650 fps and I killed a couple of deer with those loads(WInchester) , and they died as quickly at the ranges I was shooting(25-50 yds)as the high end loads I tried later(51.2 grs of IMR 4198 with a 300 grain JHP @ 2173fps) with a lot less meat damage. I don't much fancy dragging out a bunch of mangled, bloody meat like them .270 boys do back here. Finally settled down at 42.5 grs of IMR 4198 for around 1840 fps. All you need in these thick PA woods. This year I've switched to the Speer 400 gr FN behind 44 gr of Reloader 7 for around 1750 fps....Just for a change. Great woods cartridge, it is. Keep in mind that while 300 grs might be a "light" bullet for the 45, it's packing a lot more mass than what those 243/25-06 etc folks are shooting.
