Thread: .243 velocity with 90 grain bullets

Hi Grandpamac, I have discovered the slower and faster 2209 as well and have both on hand. Interesting that you mention it. I have a tin of 2209 a few years older that produces slower results, and with smaller carridges like the .243 I have to add another grain to get to what the more recent powder will do, and sometime 1.5 - 2 grains in big cartridges like the .30/06 or 9.3x62.

I have no pressure signs showing at the moment, I will continue and see what case life results,.
