I recently got a Marlin 1895 in 45-70.  I figured that the XLR model with the stainless, longer barrel and the laminated stock would be an advantage in the damp environments where moose are typically found.  Got the rifle with the intent of working up 350 gr. Hornady FN handloads for it, not to buy the factory XLR ammunition.

 

I've already installed a Williams aperture sight.

 

I've read that the case dimensions for the factory XLR rounds are slightly different from what is specified for "standard" 45-70 loadings.  If so, will this be a problem in working up my loads?  I have some reloading experience, but am no expert.  No desire to ruin a new gun--or worse, if the rifle isn't designed for standard ammunition. 

I plan on working with from the sixth edition Hornady manual and figure H4198 would be a good place to start, given the relatively lower pressures I've researched for that powder.

There are 3 catagories of loads for 45/70.

One for the old Trapdoor 1873 Springfields,
one for the 1886 Winchester / 1895 Marlin only
and 3rd, one for the Ruger #1 and #3's only.

You will see that data in any load book, at least the ones that I have.

Yup!  I plan on working from the Hornady Handbook, starting with 39 gr. of H4198 and working toward about 46 gr.  Will take some prior advice, and try IMR 3031 for comparison, which I'm told may be a better powder for the 350 gr. bullet.  I just don't have any experience with compressed loads, and it looks like 3031 may be one.  Any issues with primers going off during bullet seating of compressed loads?

a compressed powder charge will not go off.ball powders compress a little,extruded a little more.

Hi.  Thanks for the 3031 ball powder info.  Name's Mark.  Do you load for the Marlin 45-70?  I'm starting with Winchester brass, CCI primers, Hornady 350 gr. FP bullets and H4198 into a stainless Marlin XLR--never fired, but Williams sight mounted.  More a collector than a hunter, but I also hunt. This should make a decent moose gun.  Figure a dead moose in 2008, shot with a .338 ain't any deader than one shot in 1920, with a 45-70.   Anyone can get within half a mile.  It takes a hunter to get within spitting distance.
