Ever since I've had my Marlin 357 I've used 'Copper washed' bullets, mainly as they are cleaner to handle when reloading and they have given me good results.

I did a bit of gallery shooting for the first time the other evening and talking to a few fellow shooters there they said why not use 'hard cast' Kranks bullets, their opinion was no lead fouling of the barrel using them, also discussion as to use 357 or 358 bullets.

Can I have opinions, views on the use of 'hard cast lead bullets', particularly how do you decide which to purchase 357 or 358? also are these bullets lubricated? do you need to use lubricated bullets?
Thanks for any/all replies.
