If you use SAAMI factory loadings, the pressures which are already very low may be so low that they will lodge a bullet. The straight walled 45 Colt in the tapered 45-70 chamber will be a somewhat better fit than a 44 Mag in a 45 Colt (which will split the case. I know this.) Even so, the fit will be very loose with around 25 thousandths excess near the rim. If I was in a life and death situation and had nothing else but 45 Colt ammo and a 45-70, I would do it. Other than that it is not an idea worth pursuing. It isn't a bad question however. At the very least you will almost certainly ruin any Colt case you use in a 45-70.dog man said:does anyone know if 45. long colts cam be safely fired out of a marlin 45-70 gov. (336 ss
i undderstand that it can be done out of a 45 casul.
and if it can, does it reduce barrrrrel life?
thanks in advance,
p.s sorry if this is a 8) silly question
Sure-Shot said:TM7 I think you are refering to using 44 mag bullets in reloading a 444. Any time you have that big a jump from the shell to the throat you risk gas going around it, causing all kinds of leading issues, potential to do damage is just to great. Even those rifles that shoot shorter and longer shells, 22s, 22L, 22LR. If you shoot a lot of shorts you will get lead buildup that can be a real pain to remove and results in a rifle that wont chamber the LR or L if you shoot them enough. In most cases you want your bullet to be touching or very close to the lands and grooves when you fire it, especially cast bullets.
No. Case dimensions at the case head are too different. Thus the .445 Super Mag which can do with cases as short as the .44 American.TM7 said:BUT,,,,,a 44mag can be fired in a 444marlin without much consequence--I think....?
Believe me I'm not trying to be difficult, but I'm looking in the Marlin Sporting Firearms catalog, the back page with the pictures of the cartridges, and for all intensive purposes the 44 and 444 case heads look the same. The case diagrams and measurements in Mr. McPherson's book essentially show them to be the same. So, I nominate an adventurous sole, perhaps TubbytheTuba, to try out the 44mag fit in his 444 chamber, even fire one medium power load if so inclined.... :wink:Sure-Shot said:As to the shell cases the 44 and 444 are similar but not the same, base size is same 444 has a narrow band between the base and where the case goes up where as the 44 does not have that band. I believe I did read something about either using a 444 case to reload for a 410 or shooting 410 cartridges in the 444. I know you can make shot loads for a 444, one I have read about but did not try had 3 OOO balls in it.
