I'm planning to compete in IDPA SSR next year, using .38 Spcl in my model 66. It is my understanding that factory .38 spcl loads generally do not meet the required IDPA power factor. Please, let's not discuss the wisdom (or lack of same) of this rule itself. What I'm interested in is how to meet the existing rule. Any recommendations on whether I should use a heavier or lighter bullet? In the past, I've used 125 gr Rainier plated bullets, over 4.1 gr of Bullseye, with Winchester small magnum primers. I haven't chrono'ed these yet -- I will try to do that this week.
Should I stick with 125 gr? Go with 158gr? Something else?
