What OAL should I start with? 1.25? This will be out of a G20, CCI300 primers, stainless guiderod, 22lb spring and a LWD 5" barrel.Whats the thought on #7 for 200grs? Pros and cons of #7? What say Ye?
Thanks,E.
If you want 1200 fps I would go AA #9. That is the only 10mm powder I have used for the past 10 years. I buy it in the 8 lb container.

AA #9 and a six inch barrel will get you 1200 fps plus without excesive pressure. One of these days a long slide will show up at my house.
