ive been shooting a 6mm rem now for a little over a year now using 85 grain gamekings. between targets, P-dogs and coyotes its been shot alot I would estimate 2,000 rounds over the last year. Im gonna give it a break and put it away it shoots phenominally thats probably why I shot it so much I dont want to wear it out, originally it was gonna be a pronghorn and coue's deer gun which now thats likely what I will only use it for now except maybe a yote or two a year. Im now looking at buying 243 which i will probably use the 85 grain gamekings in aswell the 243 isnt much of a loss of performance compared to the 6mm but this one will be primarily a varmint rig with better barrel life.

IMO if you want a fast 6mm where brass is relatively inexpensive and barrel life shouldnt be to bad I would AI improve the 6mm rem.
