Well guys I bought it!! also got a box of factory Rem .300 Ultra's with 150gr Swift scirocco bullets. They seem a bit to light for this cartridge. Muzzle volocity I'am guessing must be around 3450 give or take. I ordered some 220gr MK's and 200gr Accubonds and 2 pounds of R-25. I pulled one of the Swifts for ***** and gigles and measured the powder in the factory cartridge 96.4gr can't tell witch brand. My dies come in on Wed. then a can get loading! going to pull the Leupold VX-III 6.5-20x40 off my 25-06 for this rig should make for a pretty good long range weapon system. Anybody with some accuracy loads with the bullets and powder listed above drop a line I also have R-22, IMR-7828,H-1000 AND IMR-4350. My lyman 47th does't have RUM info. Tell you what these 300 cases make 7mm Mag cases look tiny!!! It's going to be a long day at the range.
