had one of those for many years, finally traded it as excess to my needs. Miss it now, of course, oh well.
A quick check of an old book shows 4895 will get you into the 1700fps range at max loads, possibly a tad more. IMR 3031 will get a little more fps but not a significant amount more.
DO TAKE CARE and do NOT "crawl" the stock. In other words, make sure your scope has plenty of eye relief. I, personally never had a problem but a fellow who shot my Marlin with 385gr RN (cast, copper plated) at approx. 1800fps got too close to the scope.
Eyebrows bleed a bit!
With heavy loads recoil can be stout. The stock doesn't fit everyone real well and that can add to the felt recoil.
Shooting at "standard" (black powder speeds) of about 1300fps or so are no trouble and a lot of fun.
There is nothing quite like working the lever after the shot and seeing that HUGE case come out. DO crimp securely (tube magazine rifle) and if you load long, keep an eye on total length. The Marlin will jam if you try to feed rounds that are too long from the magazine. Not impossible to fix, but will require disassembly of the action. Keep rounds below the listed 2.550" COAL max and you should be fine on that score.
Enjoy the gun, its a good one, do your part and it will take anything that walks in North America. And they can be surprisingly accurate with certain load combinations, too.
