Ive used mcgowan and er shaw. Mcgowan are hand lapped and are good quality for the money. Shot well and cleaned easy.
Er shaw are good for the money as well. A more afordable option to try diff calibers without dropping to much cash at one time. Especially if u get in on the group buys. They are not lapped but my 223 AI stopped coppering at around 30-50 rounds amd only had very slight traces of blue when i ran butches thru it or the copper eating foam.
