[QUOTE="RockZ, post: 385060, member: 5750"] I have only shot the 300 SMK's in the fireforming loads and I am using 94 gr Retumbo loaded at 3.710 OAL which is .010 off the lands. I know alot of people who fireform with the bullet in the lands but this worked out for me as a very accurate usable load. 3 shots in 1/4"at 100yds. I never shot the 300 SMK's in fireformed brass but am going to do that in the next month or so. I just ordered 500 of them from Midway and should get them next week. So far in fireforming, Retumbo showed more accuracy than US869 for my rifle. But I haven't given it a very extensive test yet. I have a buddy with a 7MMRUM who uses US 869 and it has been the best powder by far in that cartridge. I too am interested in building a 7RUM. [/QUOTE]
