All this talk about wildcats has got me thinking...I know, DANGEROUS! You can shoot .38 spcl in .357 lever guns. What if one were to shorten a 45-70 case to 1.8" from 2.105"? Would it cycle and load well in a 45-70 levergun such as a marlin? Just thinking out loud here, thoughts?

Buy yourself a case trimmer and try it, but the rounds may or may not feed in your Marlin Lever Action. But in a single shot it wouldn't matter. |

I've been shooting shortened 45-70 for decades. Not because of the current legislation but because years ago 45-70 brass was hard to come by. When the case split you cut out the split and reloaded what was left. My father and I both had 1873 springfields. When the 1.625" proposal was passed I bought a marlin to shoot a higher pressure. It works especialy well with the 1.8". The 350 g bullets I shoot have two canalures. If you load at the longest COL it is only .050" short of a normal 45-70. The 405g with two canalures may also work but I no personal knowledge.

Your thread got me curious. I have a Remington Model 722 chambered for the .458 X 2" AMERICAN, had it over 30 years. I took one cartridge and shorten the case to 1.8" to see if it would feed into the chamber using a 400 grain Speer .458" bullet. It worked fine in my bolt action, so it's worth a try in your marlin. I would strongly advise to inside ream the neck.

The 405g with two canalures may also work but I no personal knowledge. Do you just use 45-70 dies to size or do you have use .45 acp or somethingto get the throat right? What type of performance are you getting from the 1.8" (vel., trajectory, accuracy, etc.) I'm wondering how much of an advantage (if any) this would gain me over my .44. I'm currently pushing a 240 xtp @ 1,850 and grouping 1.5" at 100 yds. This load groups about 4" low at 150 when dead on at 100 yds. |

I neck size with the 45 acp, then ground .480" off the crimp die so I could roll crimp. I'm shooting 350g @ 1800 fps with groups that run about 2" @ 100. I do get occasional flyers to 3". I only shoot this load to sight in and kill 1 or 2 deer. All of the other times I shoot full size 45-70 as they are legal for squirrel, varmints, and coyotes. With the 40-60 Marlin I neck size with the 41 mag die.

Could you provide more info. on reloading the short 45-70. I have a marlin 95 (new) looking to use for deer season and trying to work up a load. This is for the 1.625. What kind of powder and how many grains. I purchased 300 gr. bullets hope they will work. Thanks for any advise!
