[QUOTE="MNbogboy, post: 1590245, member: 18849"] Entoptics, I guess I wrote that one wrong. Intended for ar10 when he thought I was wasting ammo. What I meant to say to him is what I had suggested to you was only 100 rounds. I am sure that some may find a load with less. But covering all the bases the first time won't leave you wondering if something was left on the table. Also sorry about missing your point about the load matching with brass change. I was concentrating on the "node" issue. Finally, es/sd numbers like your last 17/6 should be all you expect. I have found grouping troubles with good numbers that could not be attributed to mechanical but just the barrel characteristics with that cartridge and load. Powder, primer, brass, bullet nothing got it to shoot. Faced it off rechambered it from 6.5-06 to 6.5/257 Bob AI. It went from 3/4 minute to 5/8. Set it back again and chambered it to Creedmoor. It now shoots like a house on fire .19, .28 & .33 last time out a -4F @ 100. I know it will be a true 1/2 moa all day barrel for what's left of it. Point is you can do everything right and it is possible the barrel isn't ever going to get any better. [/QUOTE]
