the state of michigan has a bill in the works ( http://www.legislature.mi.gov/documents/2011-2012/billintroduced/House/pdf/2012-HIB-5249.pdf ) to revise some of the laws concerning the "shotgun" zone of the state. one of the proposed changes is that rifles, with a .35 caliber and larger, would be allowed to be used during the firearm deer season. the intent is to allow pistol caliber rifles to be used in the shotgun zone. the proposal reads... that the case must be a minimum length of 1.60", and the maximum length of 1.80". since i do not own a pistol caliber rifle, i was thinking.... i just happen to have a couple of scrap 45/70 shells here, and thought i would try doing something with them. so, i shortened them to 1.790", and seated a 350g cast (ranch dog) flat nose bullet it it. the overall length of the cartridge is 2.345" (which is 0.205" shorter). i only put 20 grains of IMR4198 in them, so pressure wise, there should not be a problem. my question is, in a Marlin 1895, would it be safe to shoot a cartridge this short? i am thinking it will be ok. but i am no gunsmith. so i figured i would save my gun, and possibly some major injuries until i got some opinions back from some of you guys.
