Using a Marlin Model 1895GBL
I am new to this cartridge.
In Lyman’s 4th Edition there are several different categories for the 45-70 ie 1873 Springfield, 1886 Winchester and the 1895 Marlin.
For example, using a 405 g boolet with IMR 4198;
1873 Springfield: starting grains 31.5g thru 35g.
1895 Marlin: starting grains 36.5g thru 40.5g.
Is there any reason the 1873 load data would not work for this Marlin?
Or would my powder charge range from 31.5 thru 40.5?
Thanks!
