I just picked the little rifle up last night and cleaned it up. I cycled about 15 358429's in 38 cases over 7.5 of 4756 sized to .358, rebounded to .3585-.359 and they grouped well. Water dropped, traditional lubed( beeswax,lard, paraffin wax and a half bottle of LLA) and then tumble lubed in alox. My GP 100 loves them and this little rifle shows promise. I got 1400 fps with an sd of 10. I then ran some RCBS 150 ( weigh about 158-159) water dropped and lubed the same as above over 16.7 of H110 and got 2020 fps!!! That's a 30/30 with an 11 round capacity-- These loads will lead the end of the short 4 inch bbl in my GP100 a touch, so I only ran a few. I assume the gas cutting comes from a lack of a check. I have ordered the 358( the numbers escape me) GC'ed mold from Lyman and intend to work up some 30/30 level loads for the carbine. It will be the perfect companion for the GP 100, Vaquero and Blackhawk... in the woods, around the farm or in the truck. Does anyone have any thoughts/experience with full throttle 357 loads in a GC'ed water dropped dropped bullet in a 20 inch bbl?
Thanks!
