I've been shooting 15 gr. of 2400 behind an Ideal 308274 at 199 gr. in my Ruger 1-B for a while now and decided to try for a full power hunting load. A 180 gr. RCBS FNGC at 190gr. (Brinell 21) with CCI 200 and 50 gr. of IMR 4350 was my first try yesterday. Inch and a half at 50 yards and the barrel is clean as a whistle (recoil was plentiful). I used Carnauba Red from White Label Lube Co. sized to .309. I consider this an early success and will now "fiddle" with the components and try to get smaller groups. I want to thank this forum and all its members for all the information
shared here that has made my first try at full power so encouragingly successful.
