Differences in the bores between rifles can account for some people seeing high pressure and others not.
Higher friction that a bullet encounters going down the bore causes higher pressures in the chamber. When you coat your bullets with a friction reducing compound you typically have to increase your powder charge several percent to get back to the same muzzle velocity you had before coating because of the lower pressure that results from the reduced bullet friction.I'll be yer Huckleberry.

Any of you guys running that 27.5-27.6 grain AR comp load have any Chrono data? I found an accuracy node in that range but the SDs werent very good so I kept pushing it. Found another node in the 28.0-28.3 range with SDs around 10 and ESs around 15 and that is why I settle there. Groups were about the same.

Folks,
Here are my latest results from my 6.5 AR. It has a 22" upper from Stryker Machine and Tool based in Winston Salem, NC. Using CFE223, I was averaging 1 - 1.5 MOA. With AR-Comp as per the picture below, I was able to get sub-MOA on 3 groups 0.69 - 0.95. Below is the .69 group. No signs of pressure.
