I have 2 Miroku Winchesters 1873's, One is in 38/357 and One in 44-40 the 44-40 puts the brass behind me. The 38/357 all goes forward. And really hates 38's So losing most of the 357 Brass is a double Ouch. Best advice is sort head stamps and lose the oldest and crappyest brass in the rifle and save the good starline for the pistols. I have been told a good smith can make some adjustments to maybe help sent the brass back alittle maybe
My 2 cents
