My favorite revolver so far is this one, my GP100 5" limited edition. I got lucky and the lockup is great, the timing of the barrel is superb, and all of the cylinders measure at .357 so it SHOULD be a great shooter. Also I performed a trigger job on it, it has a Wolff mainspring, and all action parts have been shimmed so no rubbing. Trigger is exceptional! I just would like some better rear sights and front sight but they are currently out of stock at Bowen.
So getting to the question, I absolutely love this NOE 360-182 mold but I have yet to shoot them. I plan to PC them and size them to .358 and try. I would like to try at .359 but I don't think I have a sizing die for that (Wish LEE made one). But maybe my LEE .358 will size a little big. Questions:
1) These boolits were cast about a year ago. A little dirty but nice and sharp. Should I remelt them and do some fresh ones? I don't know what age has done to the hardening.
2) I have 43 cast and I would like to know what I need to do to work up the ideal load...
3) I want to use 2400 but don't know where to start and how much to move up per (how many rounds?). For example Lyman 50th has 180gr JHP starting @ 10gr and max @ 12.6. 50th has 170gr 358429 starting @ 9.7 and max @ 13.5. So from this where should I start some loads for PC lead 182gr?
4) If for example your starting load is 9gr how many do you load up @ 9gr before you move onto your next step? How much powder do you increase per step looking for the accuracy sweet spot?
5) Should I play with OAL at all? Do you guys always stick to the book for OAL?
