[QUOTE="Bart B, post: 115293, member: 5302"] [ QUOTE ] I have an old factory 670 win - 30-06 that shoots 1.5 MOA reliably when cold. Two shot limit (before letting it cool down) or it sprays. The Chrono shows consistent velocity. Any guess on the ot-six's problem?

Happens a lot with factory barrels and many aftermarket ones. * Shooter's changing his position and/or way he holds or shoots the rifle. Proper coaching and practice will fix this. [/QUOTE]
