I am going to be placing my first order for bullets, powder, and primers in the next few days. From what I have read w231 does pretty well out of the lee pro auto disk which is what I have. I am wanting to stay on the cheaper side for bullets since its just for plinking so was looking at berrys 124g 9mm rn plated bullets. Does anyone use this combo or have any advice if this is not a good combo? Also does it really matter what company I use for primers? Dont know if it matters but Im shooting a glock 19 with the factory barrel. Thanks Wanna kill these ads? We can help!
