Lately I've been seriously considering working my way into the .357 Sig cartrige. All of you that reload for the .357 Sig...are there any points of concern with the cartige compared to any other pistol round? Any issues with finiky over pressure? Any issues with the bottle neck case I should be aware of? I'll probably start with a lone wolf or kkn barrel for my G35 and see how far I can safely go in velocity concentrating on 124 and 147 grainers. ANY issues both great and small I'd like to hear about.
