Has anyone ever heard of any factory load that is too hot for
a modern Marlin 1894 in 44 cal ?

I read somewhere where a guy was saying that the
180-gr. round shouldn't be used in the rifle because the pressure
built up to an excessive level.

He was saying that this round was designed for a pistol,
because the bullet would exit the shorter pistol barrel before
the pressure built up to an excessive level.

It just doesn't sound right to me that ANY factory 44 load
is too hot for any modern .44 chamber.

But then, I don't know everything.

Factory ammo is loaded to SAAMI specs. If there were a firearm that could not handle those loads the ammo maker would have a disclaimer on every box stating what guns were not safe to shoot their loads in.

Thanks, that's what I thought.
Ammo makers have lawyers too !

I don't know about factory stuff but-I bought a new cowboy action .44mag (marlin)a few years back and a buddy gave me some of his pet 44mag reloads with unique in them and they almost locked up the action!!!!!!!!!!!!Now mind you that I finally got to my own reloads that were a bit on the warm side-22grns of 2400 with a 240grn jhp on top and the gun loved them.Which could meen that maybe some factory load somewheere could be using a fast burning powder and causing some pressure problems with rifles.

Don't bother me-I'm reloading!

My favorite loads for my Marlin 1894 are 9.8 gr of Unique with a 250 gr Keith SWC and 19.9 gr of 2400 with the same bullet. The 2400 load seems to give better accuracy but both are good enough for my purposes. Neither shows any signs of excessive pressure.

As long as it is a factory load by a reputable factory , it sounds like complete nonsense .

Did you mean 280 grain , instead of 180 grain .

If they were some one's reloads , they can be erroneously loaded too hot .

In .357 I have seen just the opposite. I have some 160 grain hard cast rounds where the box is marked CARBINE ONLY, because they are loaded too hot for any revolver.

Bought them in case I ever had to deal with a Polar Bear in WA State (because of climate change. ) Then I bought a Marlin .444 so that became my Polar Bear gun. Also picked up a Nosin M44 in case a T-Rex ever attacks my house. . .

Yes. Garrett .44mag is too hot for a Marlin.

SAMMI .44 Mag loads should not be too hot for a Marlin .

Nothing within SAMMI specs is too "hot" for a Marlin.
Yeah, you can handload them hotter, but they probably wont be too accurate. If you can’t hit what your aiming at, it doesn’t matter how powerful the round is. If you want something more powerful than a 44mag from a 20” barrel, then move up to a 444 Marlin.

Perhaps the question was misunderstood by the OP. Marlin used what they called Micro grove rifling for a while, and that was shown to be pretty lousy at handling lead bullets. With the advent of CAS, and its requirement for ONLY lead bullets, Marlin changed its rifling away from the Micro grove to something that dealt with lead well. Perhaps the restriction/comment was aimed at leaded-bullet ammo. Pressure wouldn't be an issue.

.

Another gun myth. Marlin's Microgroove barrels will shoot cast bullets just as well as the Ballard or cut rifled barrels. I shoot both types. Drop by some time and I'll show you. And stop reading those gun rags and get out and do some real shooting.

.

To hot for the action? No To long for the action... anything over 310 grains doesn't feed right IIRC.

Garrett .44 mag is not too HOT for a Marlin, it is too LONG for a Marlin.
