Just read a very complimentary review by Nigel Greenaway of the bullets of BES Products in the UK. You can look it up in the July issue of Targetshooter - free webzine. 174 and 215 grain copper jacketed bullets are offered in 303 and apparently are used by Kynamco for their own 303 rounds. no website but email address is mseller208@aol.com or tel +44-1302-330726
