I have about 1400 Rainier 200gr RN plated bullets I'd like to load up for my 45ACP 1911, and a pound of SR-7625 I'd love to get used up. No point hoarding one pound if I'll never see any more. I know that you should use lead or mid-range jacketed data for these but the only one I can find is from Hodgdon's online source:
200gr Cast LWSC
IMR SR 7625 .451" 1.225" 6.2 836 13,000 CUP 6.9 952 17,200 CUP
200gr Speer JHP
IMR SR 7625 .451" 1.155" 6.0 861 13,600 CUP 6.6 941 17,100 CUP
With this I would think I would start at about 6.4 gr with no more than 6.6 or so. My Lyman Auto Pistol book also lists 5.4 to 6.7 gr of SR-7625 with a Lyman 452630 200gr. Does anybody else know of anything with this powder and a 200gr bullet in 45ACP?
Also, how do you go about figuring out C.O.A.L. with something like this? 230gr RN usually list an OAL at 1.275", and a 200gr Speer Gold Dot JHP is listed at 1.178". I see some other discussion in forums talking about setting them at 1.200", but can anybody confirm?
