hello, the newest handloader, issue 242, august- september has an article about single-shot's. he talks about encore's, and other type's of single-shot's. you should get this issue if having problems with your groups. WWW.riflemagazine.com for a web address. on another note my encore shoots fine with reloads. most generally under what is published for max. i didn't have good luck with factory ammo. caliber is 7mm-08. my next barrel will probably be 6.5 X 55 swede. hopefully this winter. buy the magazine, it may help you. thanks for your time. later
