Archer needs help with rifle accuracy
i am new to rifle shooting, and have recently purchased a used Win. Model 70 in 300 Win Mag. The gun shoots in a 2" circle @100 yds. with PMC ammo, this cartridge uses a 180gr. barnes bullet. After 3 shots the groups get wider, I am assuming from barrel heat. I understand a higher end bullet would probably help tighten the group. Is there anything else I can do to shrink the group size.
Thanks
Thanks

RE: Archer needs help with rifle accuracy
that aint bad shootin for a factory rifle. i wouldnt complain. exspecially in that caliber for a newer shooter. better ammo doesnt always shrink groups..the goal is to find the ammo that the gun shoots the best. could be 5$ a box or 50$ a box...try a couple diffrent bullets and weights and see what it likes.
another thing..since its used, get some GOOD bore sovlent and soak and scrub the bore. get it spotless. that may help...who knows if the other guy ever cleaned it properly...could be fouled up a bit...
but 2" at 100yds isnt anything to complain about...but could probably be imporoved...good luck...

Of course, loading your own ammunition would let you work up a specific load customized for your rifle, and that is the most effective way of finding what shoots best in that gun.
If you think barrel heating is causing your groups to open up, try shooting one shot every five minutes, allowing the gun to cool between shots.
