I have a 'modern' Marlin 1894 in 44-40 with 20” bbl, microgroove rifling. I want hunting bullet loading for deer, pigs, etc, here in Texas.
I know I need to crimp the cases well for tubular magazines. I've read I need an oversize bullet, .429+, a harder alloy and with gas checks for good accuracy & no leading at higher velocities with hotter loads. And 'maybe' that heavy bullets won't stabilize accurately in the 1in38 twist barrel.
The only one I can find is the Lyman 429640 HPGC, which seems to have all the features. However, I'm concerned its 450g is too heavy for my 44-40 and microgroove rifling. And I haven't found any load info on it yet.
Have also found molds for lighter 210g gas check bullet, Lyman 429215, which has a good reputation but no crimp groove. Don't know how they will work of how to crimp so they aren't forced back into the case in a tubular magazine.
I don't know about other bullets yet, but very open to suggestions. My intent is to get some for trial and then the mold to cast what works. Not into Cowboy Action Shooting right now
1. Please advise as to whether/how the 429640 would work in the slow twist microgroove barrel, and maybe load info,
2. how to crimp non-crimp groove bullets in thin neck 44-40 so they don't telescope into the case... (I have Lee crimp die).
- of another good .429+ bullet (gas check and crimp groove.?) suitable for my needs.
Be Well.
