[QUOTE="MontanaRifleman, post: 1617160, member: 11717"] My first "long range" rifles where used Rem Senderos in 300 RUM and 25-06. They shot pretty much everything, including factory, sub 1/2 MOA, .2's and .3's regularly. The reason I say this because some rifles will shoot mediocre ammo well and I believe the reason in this case was mostly the heavy Sendero contour as well as the HS Precision aluminum bedded stock. Back then my knowledge of handloading was basically beginner/novice level. I handloaded without the aid of a concentricty gauge and had no idea what I was producing in that sense. Sometime after I sold those rifles I bought a concentricity gauge and i found a few leftover 25-06 handloads which I ran on the gauge and found out that some of them were as much as .010 out. There is no way to quantify how much runout will affect your accuracy. There are a lot of factors. Your rifle is a system with many factors, parts, components and workmanship. If you are handloading without a concentricity gauge you are sort of flailing around in the dark. Recommend you get one and check your fired case before sizing, then after to see the difference. Also run a few cases through your sizer without an expander button. You will almost certainly see that the expander button is causing runout. Two benefits, to using bushings, one, less runout, two less working the brass. If you want quality handloads, get away from standard dies. [/QUOTE]
