[QUOTE="J300UM, post: 462541, member: 9866"] I had my 300UM rebarreled a couple years ago to a 300 Weaver (300UM W/40 degree shoulder and less taper). I was only able to achieve about 100fps over the RUM. My accuracy however came in at the same velocity as the load I had for the RUM. If I had it to do again, I would have just stayed with the RUM and eliminated the fireforming process. Buy the brass, prep it, and shoot it. The rifle is very accurate ( 1.5" @ 600yds all day) but I think my accuracy edge came from the new barrel, not the cartridge. It may not be the exact same thing as the Tomohawk but it sounds very similar so I figured I would share my experience. [/QUOTE]
