Have a ladder loaded up of 93.6, 94 & 94.4gr. of H1000 in my fully formed cases. And also a few in the once fired cases to re-sight in with the bigger March back on the rifle. Thinking I should make it out Friday morning.
The left 3 are once fired and the right three are twice fired.

Ran out super early before work and shot my ladder at 500 yards. It's not terrible, but I still don't love the patterning of the groups. It appears my gun just isn't destined to be a hot rod 
hahaha. 93.6 is a clear winner with this very small data set though.
I actually shot the 94gr. first, then 93.6 & then 94.4. Waiting 3 minutes between every shot for barrel temp consistency.
I also shifted my turrets between each group to separate the impacts a little bit. The groups aren't exactly where they would have hit in relation to each other if I would have left my zero the same.

The CCI 250's are much hotter than the 215's or WLRM's.
Interesting the patterns are all the same, time to start playing with the seating depth or try the 180HH if you are set on running Hammers.
I'm know both you and the gun are capable of better but this one isn't coming easy as the last one LOL

Actually the second shot of every group. Which I think is more of a coincidence than anything. But still strange lol

actually if I'm not mistaken its been found the F215 is hotter than the cci250 but the cci250 has a harder/thicker cup..
pretty easy too knock them out!!
Load up 3 if you can with the 94.4 and CCi250 pressed too .0065 though depth and check

I would say its not a coincidence.. out of curiosity how come you wait so long between shots .. the way look at it is .. are you going too have 3 to 5 min if you have to put another round in a critter too put em down??
I always shoot three one right after the other for my groups
I want them too stack cold bore and warm

I'll post my CCI 250 vs 215 M vs WLRM 300 RUM results later when I get home but the CCI's were way above and blew the pockets out.
Do most of the groups you've shot out of that rifle have that flyer? If so I'd be looking at the bedding or see if something is touching the barreled action that shouldn't be. Seems like too much of a coincidence to have three different charges have the same looking group with two right in there and one high and to the right. Are you single feeding these or feeding them from the magazine box when shooting the groups.

sounds like a load . pressure related problem .. not primer problem
I've done the same test with the 300 RUM and the fed 215M always showed more velocity, pressure, and higher ES than the CCI250.. heck I've done the same test in about every thing I shoot them in from a 6.5 saum too a 338-378 weatherby ... same results
now .... when dealing with 120gr or more powder needing burned, I use the fed215 because of the hotter flame.
