It's hard to beat the 240 XTP in the Marlin for deer. My 1894 is my Cowboy gun now and I seldom hunt with it since I had to take the Williams sight off to be CAS legal (doggone it), but the XTPs are .430 whereas most jacketed .44 bullets are .429. It does make a difference in my mid-80s Microgroove barrel.
I had great results with the 240 XTP and AA#9 and IMR 4227, and I'm sure the factory loads would do just as well. The .44 is not a 200 yd gun, but it hits -hard-.
Mine has shot mostly 210 RNFP lead over blackpowder the past several years, wonderfull little rifle! The avatar to the left is that same load in a Ruger Vaquero, my better half behind the trigger.
