Thanks alot for the opinions guys. So if i loaded up a couple hundred 55 gr 243 bullets @4000 fps out of my 1-8 243 (Just to explode prairie dogs) i shouldnt expect much difference in barrel wear or worry about burning up my barrel with 4000+fps? i usually use 95 gr berger vlds @3050
The 55gr bullets will not likely hold together at 4000FPS, that is 360,000 RPM the copper jackets are to thin on varmint rounds, 3500-3600 FPS at best will be the max you can push them, that is 315,000 to 320,000 RPM.

RUMs are like woman in Stiletto heals, you know they are going to put you in the poor house, but that has never stopped anyone from pursuing them.
