I know this has been discussed hundreds of times I just want to get everyone's opinion . I been reloading awhile and been just reloading to Sammi specs. Recently I been reading a lot about more things to do to get better accuracy. I just ordered a oal gauge and a comparator to try and get closer to the lands and measure the ogive. My question is how consistent does the trim length need to be? Most of my brass is 1.752 to 1.756. I have some brass that is 1.745 to 1.749 but that is separate. Will the difference in thousands affect the accuracy or bullet seating? Thanks
