I would like to reload 44mags for this marlin but I want to know how heavy of bullet have you guys loaded and still functioned thru the action. I've reloaded the 240's but have not been impressed by their performance. Looking for something around 300gr.

265 grain Hornady with Win 296 powder.

OK, I could be confused again but believe Marlin's twist rate has issues with bullets heavier than 260grs..

The various Rossi made M92s may need cast (.432 bores) but do better with the heavier boolits.

EDITED: There you are, buckeyeshooter's does well.

I shoot 300 grain hornday xtp's in mine behind a max charge of 2400. I gt exceptional accuracy and they work well on game. My 1894 is one of the microgroove barrels that is not suppossed to shoot heavier than 240 grainers well, but it works exceptionally. Give it a try and see how your gun shoots.

My first "deer" rifle was a Ruger Deerstalker.
I killed several deer with various factory ands later handloads with 240 HP and SP bullets.

For the normal deer I think they are hard to beat.

If I was hunting big pigs I have found the Winchester 250 Partition to work well and in the handgun the Speer 270 SP good as well.

The 44 Mag rifle kills game way beyond what its paper ballistics would suggest, out to at least 125 yards [as far as I have used it].

I currently have a Winchester 44 Mag Trapper.
I would not hesitate to use it for even brown bear protection, with the proper deep penetrating bullets.

My wife and I have carried it for Grizzly protection in Montana.

I've got an octagon barrelled 1894 limited in .44 and I've had good luck with the 300gr XTP and a 325gr LSWC with max loads of W296 out to 100 yards. I'd bet that 325gr'r would ruin most critter's day if they got up close and personal

Thanks everyone for all the good info. I'll will be trying some of it in the near future. Looking forward to carrying next deer season.

Last year I shot 5 hogs in one weekend with Nosler 240gr SP. Hogs weighed between 80 and 196 lbs. All except the smallest dropped with one shot each. Little one took 2 shots.
Exit holes on all shots. Ranges 50 to 109 yds.
Hope this helps. John
