some people seem to think I am running too much clearance but I really like how its been shooting for me,,I like for a bullet to go into the neck of a fired case with no pressure,, and anything bigger than .265 wont allow it to go,,I tried loading some with the loaded round measure at .267 and I could have just knocked the primer out and loaded it back without even using a size die,,and it shot like crap,,I went to .266 and it got better,then .265 and it shot like a lazer,,

little wider ES than my long range loads but it shoots really well out to 300 yards,,,no questions or anything just an observation,,

Sounds good :)

And I misdoubt that dropping the ES down to 10 would change anything, might make it worse!

Out to 300 yds

Were the first two shots thru a clean cold barrel?
Or had you fired a couple shots before the test string?
