Is there any kind of miximum overall length for a cartridge in the 1894 45 Colt.
I am having problems with an LBT style long flat nose design that just won't chamber but gets hung up.
Feeds shorter length rounds with no problems.
What is the OAL you're presently using? Using RD's 290 grain I'm crimping right at 1.595" with no feeding problems.
RD 290 grain at 1.595 OAL
Speer 300 grain JSP at 1.654 OAL
Hornady 300 grain XPT at 1.62 OAL
OAL is exactly 1.735".
It is a custom hollow point/solid bullet that I cast.
1.7+.........ouch, that is pretty long.
I sometimes shoot a 300 gr. Speer GD Hollowpoint or Flatnose bullet at 1.66 and it works fine. But, its pretty long. When you get in the 1.7+ range, you're getting in to .454 Casull OAL ranges.
I ain't saying its not the bullet, but I will say that 1.7+ is long.....maybe toooooo long.
1.60" is the published standard OAL for the 45 Colt. Some stretch beyond that and get by with it, others don't. I run just over the published standard but I'm firing from a handgun so doesn't matter so much..... your mileage may vary.
Tom, the Hornady and Speer jacketed bullets I listed don't have much of a meplat and the ogive is pretty far back from the nose. That's why I can get away with a little extra OAL on those. On the other hand the RD cast has a fairly wide meplat and the ogive isn't very far from the nose end. I suspect if I tried to load it with a OAL as long as you're using it would not feed in my gun at all.
Here is a picture of the loaded rounds that I would like to get my rifle to digest.
These bullets were cast from a custom mold and were especially designed for the Ruger handguns.
I flat out love the design and the capabilities of this bullet.
I really hope that I can get this round to feed properly.
If not then it will be time for another mold.
For some reason when I see LBT I immediatly think of a WFN design which sometimes even with a proper OAL will have feeding issues in some rifles. Had I paid closer attention to your post, you did indeed say it was a LFN design. Just my opinion but I don't think there is any way you'll be able to get them to feed properly in the Marlin rifle. I also have a H&R 45 Colt Buffalo Classic which those bullets would shoot great in, so if you need an excuse for another gun........there you go.
