Any problem using Mag primers and 2400 in 44Mag?

Cubslover

Am I safe to assume that Magnum primers won't hurt anything when used with 2400 in a 44mag 1894?

Also, the only reloading data I show for 2400 is for a 5.7" Revolver.

18.7gr behind a 240 JSP for 1440fps.

Is this a good starting point for a 240gr Nosler JSHP out of a Marlin 1894?

Shouldn't hurt anything. I use magnum primers in everything, just remember to stay a grain below the max if the data listed uses a regular primer. You can still get to the max with some gun and load combos, just make sure to carefully watch for signs of pressure, just like you would any other time.

I load LOTS of 2400 into a 44 Mag. I have always lit it with a mag primer. The case is VERY close to being full and I wnat to make sure it all ges lit on its way down the tube. Your load seems fairly mild and should shoot great.

I always use a fairly heavy roll crimp with 2400 to ensure full ignition. That is a good load to start with.

A mild load????

Alliant shows 18.7gr as MAX!

Jon's advice about staying a grain below max. matches my own experience in as much as my chronograph shows virtually identical velocity for the following 240 jacketed loads in my Blackhawks;
21 gr. 2400 and CCI Mag. OR
22 gr. 2400 and CCI Standard
As always, regardless of primer, start well below listed max. and work up slowly and carefully. I have dozens of reloading manuals and listed maximums can vary significantly. I've hit max. in my gun before hitting max. as listed in any of the manuals, and I've (on rare occasion) gone over listed max with no sign of high pressure and excellent accuracy.
There are so many variables.
Good luck.

Ok, thanks. I was kind of wondering whether the different manuals show significantly different max charges.

Thanks again.

My Speer #10 manual shows a 44 mag RIFLE ONLY load of 20.2 grains to MAX of 22.2 of 2400 powder, using cci 350 primers, and a 240 gr Magnum HP or Magnum SP bullet. That should run 1603 - 1756 FPS out of a Ruger carbine. They DO reccommend a "generous roll crimp". Also may be a good idea to use a magic marker to color the case heads of RIFLE loads so they do not get into a REVOLVER. Your mileage may vary.
