[QUOTE="Jeffrthehunter, post: 1709473, member: 98990"] I have been shooting a new build for a few months (6.5-284 Defiance action with proof barrel) and have really struggled to find a load with low ES. After several attempts I ran a ladder that showed 53.4 to 53.6 of H4831SC was single digits for ES and shoots 1/2 MOA out to 500 yards. Problem is that with fire formed brass I get a hard bolt lift (last 10 degrees), not real hard but there is some pressure there. I know if I drop to 53.2 it will go away but the ES goes to 20 plus. Deer season is just around the corner and I would like to stick with this load (53.4) and maybe try something different in the off season. So the questions is, is this a horrible idea? Will it damage my Defiance action? Any thoughts from you more experienced gentlemen would be appreciated!!! 9/11 After some thought I realized that the hard bolt issue at 2950 fps seemed new. I have loaded several hundred rounds (ladder testing and fire forming brass) with some loads running over 3000 fps and never had a heavy bolt issue (did have some primers start to crater). I then realized I had changed my brass prep a few weeks ago and started wiping each case below the shoulder with Lyman case lube prior to full length sizing. I would wipe the brass off with a paper towel after sizing but never really cleaned the case. Today as a test I cleaned the rifle chamber and several rounds with de-greaser and went to the range. No heavy bolt lift!!!! So crazy how the small things can cause problems Thanks for all the thoughtful ideas and info, I will do some more shooting this weekend and give updates if something changes.
