Re: Need load data for 300RUM- Barnes 180gr TTSX &/or 200gr LRX
For the 200 LRX I use 85 grains of retumbo and a gm215m primer. Loaded to 3.662 for .090 jump this load shoots at 1/4 moa and cruises at 3142 ES of 10 and an SD of 5. This is from a 28" PAC nor barrel with a tight neck chamber. Look up 200 LRX and you can see some of my pics on what it does to caribou. Little much, but would be perfect for moose and bear. I used a GM210M in a 220 SMK load to lower es and sd also and had to add a grain more to get velocity back, so this is another option. Just give'em a bunch of jump and push them hard they are generally very forgiving and like a specific powder. I would try retumbo, magnum, R25, US869, and H-1000 in that order. The bc on this bullet is conservative from barnes I would estimate it at .6. Good shooting
