I can't say enough about this great British calibre, though the only draw back is that it's a very high pressure load, and the burn is very hot on the bores. You must really treat a 318's bores with lots of tlc if you want it to last a lifetime. As such it's not recommened for the unexperienced.

"...and the burn is very hot on the bores." What powder are you using? Cordite? With modern powders it's not going to be any harder on barrels than other cartridges of a similar powder to bore capacity ratio.

"...it's a very high pressure load." Hardly; at least not for bolt action rifles.
