and as far as the loading goes I've used Lapua and PPU brass, Hornady 285, Sierra 250-300, Berger 300, and Lapua 300 bullets. +.015 in, just touching, and .030, .045, .060 off the lands. Powder is Retumbo, RX25, us869, 8700. primers are CCI large mag and GM215.. and I used redding, forster, and rcbs dies...

I've developed loads in the my other guns without issues. Until this one. As soon as the barrel starts to heat up it turns into a shotgun. One shot is ok, if you have to follow up its not going to be where you want it. And as far as I'm concerned if you cant push out 5 shoots where you want it then the barrel or gun is junk...... But that's my opinion.
