A whole lot of dead critters all the way out if you get good groups

Alright Brotherhood, I need help!
Factory Sendero, doing load development for Barnes 168gr LRX. No reliable load information for this bullet, so I started at 78gr of Retumbo, and worked up. Best accuracy and consistency was at 83.5gr. Approx 5/16" group at 100yds, with all three touching Avg velocity was 3290fps, with an ES of 9.5. BUT, bolt lift was fine, but extraction was tough, and there is very slight primer cratering and a very faint ejector mark. I think I can safely assume this is max load of Retumbo in this rifle!!! Is this safe enough to keep shooting, or should I try working with one of the lower charges that had a fair group?!?!

I'd go down a couple of grains and take a bit off the pressure peak.
You are probably at 75 Kpsi for it to be tough to pull back.
A couple of questions though. Are you fl sizing your brass? Has that brass been beaten up with a hot load before?
Marks on the brass head are never good and are usually consistant with at least slight over-pressure. Before you give in to sub standard accuracy play with seating depth on the highest charge that doesn't give ejector marks.

Have a good one...

Guys, I chased another deamon from my 7stw. It's even 85 degrees out there and she still shot.
The new trigger guard screws pull the groups down to .7" at 100 in a gusty wind with rl25 and the 140 ab. The other day she wouldn't hold 2 moa after the screws backed up to snug. Went with hex-head screws as others on the forum have done. Damn near throught the whole rifle already, why did I go with some other fool's idea of custom and not my own??? Lesson learned.
