[QUOTE="Minnow, post: 424928, member: 26173"] I have a Browning A bolt 1 stainless synthetic stalker .270win that groups about a 1.6" @ 100yds on average. Today my first group of three shots on a cold/clean barrel was not consistent. My second group of three measured .070" which I consider super for a stock hunting rifle/sporter barrel with factory ammo. At 200yds my groups average 3.44" with some as small as 1.80" and as large as 4.45". I was shooting mostly Winchester PowerMax, along with some Hornady BTSP 140gr. and Winchester Ballistic silvertips. I'am resting the forend and butt stock on sandbags and getting a nice steady hold with a slow trigger pull, but my groups seem to dance around. I'll be the first to suspect human era plays some roll in this to a small degree, but this rifle as never been a tack driver even with trying various ammo. [B]It seems like this rifle groups much better when it gets warmed up.[/B] My scope is a Leupold VX3 10X with Leupold two piece mount and rings. I would like get this rifle consistent and shrink the groups down a little bit. MOA or better? Please advise... [/QUOTE]
