I am going bear hunting (Black Bear) and im planning on using my Marlin 44mag, This Marlin was manufactured in 1969 and is one of the most accurate lever guns I have fired. My question is should it handle thge larger grain rounds today like corbon 300gr JSP. It cycles fine I just dont know about the pressures of these hotter rounds. The Marlin is in perfect condition and has only fired 50rds that I put through it yesterday.
I bought this Marlin from a family member who bought it NIB and never fired it. I fired the new Platnum tips 250gr with no problems but I want to shoot something alittle bigger if there is no concerns with the pressures.

Should be ok, this matches what many over on leverguns and Marlintalk have said.

check the OAL, some 300 gr. are too long for the Marlin carbine.......I loaded some for my Marlin that were too long, but, will shoot in the Ruger Super Blackhawk........

Only thing to check is to see if the 300 gr bullet will stabilize. Marlin puts a maddengly slow twist in their .44 mags. One of mine shoots 'em fine, the other not worth a hoot.

Well I really checked out the action while cycling rounds and the 300gr just barely feeds, I can see it catch on the feed tobe alittle. The 270 gr is fine so thats what ill go with. I dont want to risk those 300's getting hung up.

If you are reloading for the Marlin, check out the Hornady 265 gr. FP....this bullet looks like a good one for the 44 mag carbine..........
