[QUOTE="5RWill, post: 1768772, member: 98561"] I'll be able to update in two weeks soon as i can get home on the 13th. The 180 is a looonnng bugger. I didn't really look at COAL without the comparator but even at my lands it fit in my Alpha 7rd WSM mag which is 2.970 IIRC. Have a feeling because of the sheer length possibly dipping into powder capacity and the bearing surface of this bullet that 3000fps in my 24" proof is going to be hard to achieve realistically. As far as fitting it at 2.950" and achieving 2800-2850 out of a 22" barrel i think that should be doable. I could be wrong on the COAL as i meant to repeat the process of getting my distance to lands with a fireformed case but upon trying to resize felt some significant resistance and went back to loading fireformed loads. Figured even a non fireformed case would give me some starting measurements though to ballpark it when i do fine the COAL with a fire formed case. [ATTACH=full]160774[/ATTACH] [/QUOTE]
