I have taken a few deer with a marlin 1895.
Regular old 405 cast is probably my favorite since it is cheap to shoot and I shoot it enough to know where the bullet will go.
The 325 ftx is good too. You will have to shorten your brass a bit if you want to hit the crimp groove, but if you have a single shot it may not matter at all.
The nosler/combined technology 300g bullets can work fine as well! My rifle is probably the most accurate with these.
Preferred powder is h4198. I do not shoot anything crazy. I get the 405 going about 1500 FPS and the 325 about 1750fps. The 300 was about 1800 fps. 38g on the 405, 45 on the 325 and 48.5 on the 300. More than that and the rifle is kicking pretty good. No pressure issues in my lever gun, and room to go up, but I dont see a need. For me both bullets were plenty accurate and going fast enough to kill deer (or pretty much anything else) anywhere I would use that rifle.
