Got dads old Remington 30-06 out to use as a back up (divided most of what the boys wanted) this deer season . I believe it has a 1-10 twist, 22 inch barrel . Which is more likely to group better ? I bought a box of 150, 165,180 . All pointed soft point core- lokt. Figure some on here have had experience with this selection .I know there are better choices and reloaders can beat them to death " BUT"of these three one will produce a winner . Actually have already shot the 150 's a few years back . They were about 1.5-1.75 as far a group @100 .
