Yeah, the ol' Gov't is no slouch. And better still, that 325grn at 1800fps is only loaded to factory/trapdoor/standard SAAMI specs. That Marlin 1895 will throw a lot more heat if you feed it the powder. My wife hunts with an 1895 Guide Gun each winter (one of our 3), factory Hornady Leverevolution 325grn FTX's run 1795fps average out of its short barrel. I can push the FTX's up over 2200fps, and have pushed 400grn pills up over 2000fps in the past in that rifle. I've killed bison over 2,000lbs with the 45-70, it's a thumper.
The downside, of course, is that shooting very far with a sub-Mach-II round isn't always easy. I have 30" of drop on standard loads at 250yrds. That might not seem so bad when guys are used to big bore rifles, but the "flat shooting only" modern hunters in the USA are pretty biased against cartridges that need that much air under them.
