I recently started reloading for my 6.5 Creedmoor. I've found a load that is consistently shooting in the .3's however I'm getting a very slight ejector mark.

6.5 Creedmoor
140 Berger Hybrid Targets
41.0 Gr H4350
2.82 COAL
Peterson Brass

Velocity is very consistent...2685 with less than 10FPS max spread.

The book max for these that I see is 41.5GR...so I'm half a grain under. Bolt lift was fine...maybe slightly stiff but I only noticed it on 1 shot out of the 20 or so I fired. The primers looked fine, no cratering. (pic below is after I resized them).

Should I be concerned with using this load? Certainly won't go up from here...but with this velocity and being 0.5 grains below book max...just surprised to see a mark.

That's where I like to load one case and fire it six or seven times, see what develops with repeated firings.

As far as velocity goes, its right where the book says it should be.

I tried backing off to 40.5 grains, it had a very very slight ejector mark at that charge.

Temps were about 75-80 degrees...so pretty normal.
