[QUOTE="Chippewa, post: 1660079, member: 86093"] I've been reloading for a 300RUM C.Arms Ridgeline for awhile now. And to say after all the reading up on here, LRO, and other resources, I'll just share my boiled down set-up and routine. So I fully Devcon bed the factory stock and my optics rail, shot/clean broke in the carbon barrel, mounted NXS 5.5-22x56, and running 212eldx @ 3050fps. Recipe: mag length 3.69"oal to tip in Norma fire formed brass, 90g H1000, 215M primers pockets just brushed. Following the shoulder bump an neck tension resize back .003" routine of Jeff Brozovitch You Tube vids. Also "vld" bevel insides of neck and use Hornady Unique lube on shoulders then on bullet base before seating but after powder added. Brass is really holding up nicely. On 5th reload so far. Recently have been wet polishing brass then, length trim if needed, then anneal with homemade drill socket stand an started that before third resize. The wet method may harden brass but it does clean inside so capacity stays the same. I fought ES issues as well an really saw number drops once lubing bullets and annealing. Also I switched to Boretech Eliminator an clean after each session. Also, Also, try an watch heating effects. As your cooling between shots bring a don't put next round in chamber to soak heat.... Good Luck. Keep shootin [/QUOTE]
