.40/65 loading data?

MIKE WISKEY

(new rifle to play with, looking for suggestions)I've got some basic data for this using xmp5744, trail boss, and xmr-2495. Rifle is a 1888 martini conv. in 1899 to .303 (smaller firing pin tip). barrel is a 34" douglas 1/2 rd, 1/2 oct. .410" grove dia., bullet I want to use is the Lyman 360 gn. pointed bullet. I'll probably shorten the barrel to 26"/28" after I shoot it a bit (so I don't need wheels to move it far).

A friend of mine that died a few years ago had a M1885 40-65 for which I had loading data. some was with blackpowder, but shooting it caused a major mess and significant clean-up. Loading with smokeless powder wasn't "original", but it did work out a lot better. The loads were with SR4759, and 4198. If interested in those, I can check my records.

thanks ray, if it isn't too much trouble. I'd like to shoot mostly smokeless, but I'm also going to try 777.

nononsense

Mike,

Here are a couple but you'll have to do some testing:

Finally found the data. After my friend died, his widow was going to sell his 1886 40-65 to me, but a son-in-law convinced her otherwise, so the data that we had developed went into a corner- but alas here it is: We used Lyman moulds, #2 metal, WW cases that were a bazillion years old, mould #403169, weight about 260 gr, 24 gr of Hercules 2400;. Mould #403149 bullets weighted bout 330 gr, 33 gr IMR 3031.

I didn't have a chrongraph available for the shooting, but based on the trajectories velocities were sufficient for hits on deer out to about 150 yards.
