[QUOTE="nksmfamjp, post: 2767011, member: 1951"] First, what rifle are we talking about? Second, what do you want? I used to want “the best I could make my rifle shoot” I would shoot hundreds of development rounds. Then I decided I needed my ammo to be repeatable. So I added a 5 groups of 5 test. These tests sometimes were terribly unrepeatable! Many times I shot 5 good groups. Sometimes I would print groups from 0.6 - 1.7“ in 5 groups…..after 0.5 moa development groups. Now I want to know what the smallest target I can hit with ~95% reliability at 100 yds based on expected rifle performance. A word of caution….this is a new road for me based on many failures of old methods, seeing how quickly my 6mm PPC groups came together…..and listening to the last couple Hornady podcasts. First, I set a reasonable expectation. Custom Bolt gun - < 1 MOA at 100 yds Factory Bolt gun - <1.5 MOA at 100 yds and so on…..there are some variations to this rule. Custom bolt guns like my PPC are going to get tighter standards.….or other guns that just shoot better get a challenge std. You are probably scoffing since I’m not holding $4000 custom rifles to 0.25 MOA like so many say. Well, the X ring in F class is 1 moa. So a 100% 1 moa system wins f class. 1 moa is minute of mule deer at 1000 yards. 1.5 moa is minute of elk at 1000 yards. So, my next rounds are pick bullet, powder, etc. Seat to the shorter of lands -0.030”(0.050” for monos), Mag length, full bearing surface contact. Load a ladder to find max pressure. You know the signs. I like bolt lift and ejector marks. Back off the appropriate amount….consider current temps vs max use temperature. Load 20 about 0.5% back from no pressure signs at any temperature level. Seated the same. Shoot them. If they shoot bigger that your expectations, stop, disassemble and change something…. IMO, if you can get to 20 under 0.75MOA, shoot a few 3 and 5 shot forum/Facebook groups! I think you will have plenty of wall hanger groups for sharing and you will have a perfect zero and a good knowledge of what you can hit 95% of the time. You will also have a rock solid Sd! Those combined will make ringing steel like ringing a doorbell! [/QUOTE]
