Is it necessary to crimp 444 marlin?

I am loading hornady 265g Ftx for a single shot. Is crimp mandatory?

Nope.

No and you could ignore the cannelure location and seat the bullet close to the rifling. You could also ignore the short trim to length required of that bullet for use in lever guns.

My buddy lost a nice buck to that bullet. Bullet hit bone and turned into a Vmax. Superficial splash wound.

No. The reason for crimping the .444 and other rounds traditionally used in a tube mag are to keep the bullets from getting pushed deeper into the case from recoil and spring pressure. That can cause feeding and pressure issues.

You surely don't have to crimp , but I'd mark
the box or put a note in with the ammo
that it's not crimped and for use in a
single. I have lever and singles both,
so I do crimp for possible interchangeability
if necessary ( although I have separate
batches for each firearm)
Even though I keep detailed written
records of my loading, it's a good idea
to have a note of some sort with the
ammunition in case of another person
getting your specifically loaded ammo
to prevent any kind of mishap. I have
some hotter rifle loaded pistol caliber
ammo that might be unsafe if used in
a handgun, and it's marked as such.

While I've been pretty much a by the book reloader, I've used different colored Sharpies to mark the primer and/or bullet of special loads with info on the box, This way you can ID the round when you use it or if it gets separated.

Thanks for the helpful info!

Bull,
What rifle are you loading for?

If a Marlin, then I suggest crimping in the cannelure with a Lee Factory Crimp Die.
Seat and crimp in separate stages.
Even a T/C Contender will benefit from the improved ignition.
Because it’s a relatively thin straight wall case, you’ll need to flare the case before seating the bullet. Then you’ll need to at least lightly crimp to remove case mouth flare.

For deer or pigs, the Hornady 265 was made for. For larger game, a 310-335gr cast is preferable.

I suggest the Lee 310gr .430 RFN-GC. The 1/38” twist should stabilize it.

I am loading for a single shot H &R handi rifle. Compressed loads with Ftx bullets caused reloaded rounds to be tight in chamber. I ran back thru resizer. I know not best idea .

Bull ... so you're a gamblin' man huh? Lol, I learned my lesson, the hard way, about why we don't try to resize a crimp bulge in brass with a seated bullet in place. It became a rather famous thread over on Cast Boolits. I included a bunch of pictures in my effort to compound my embarrassment.

My rounds were not crimped. When i seated the 265g FTX ON A COMPRESSED CHARGE the bullet swelled slightly. It isnt crimped.

444 Marlin is a heavy recoiling rifle, I would say yes. Ctgs. in magazine tubes need to be crimped

I am loading for H &R handi rifle.single shot.

I reload the 444 for a single shot CVA Scout. No I don't crimp and no I don't use shorter brass that came with the factory 265 FTX ammo.
