I have a new winchester extreme weather in .270 win I am getting 3/4" to 1 1/8" groups at 100 yrds depending on what factory load I am shooting. This model has the Bell and Carlson composite stock with an aluminium bedding block. And the MOA trigger. Would glass bedding the action help? Or is this about as good as I should expect out of a factory barrel? Any other tips u experts have. Thanks in advance for any replys.......
