I load for a Rossie and a Winny Model 1892 in .357 Mag ( some one converted the winny , some time in the past ) . And a S&W .357 wheel gun .
I have a lot more .38 Special brass than I do .357 brass .
I load Lee home cast bullets . I seat the bullets ( in .38 Special brass ) one groove further out / longer . This gives me an OAL and internal volume ~ that of .357 Mag brass .
This pretty mush solves the feeding problem . Assuming the bullet nose / shape feeds OK .
RN or RNFP feed well in hand gun caliber lever guns . Anything else may or may not feed OK .
Different guns have different idioschencries (sp) .
Of course , the wheel gun does not care .
God bless
