6.5 PRC load question

[FLHunter88]

Hey y'all. Question on CBTO. I'm working up 2 loads using RL 26 with Hornady brass. 57 and 57.3 shot the best. My question is. I loaded these to 2.288 CBTO. I'm wanting to try and get better accuracy out of these loads. If I push the CBTO out to 2.298, would I need to increase my powder since there is now more volume in the case to maintain the same velocity?

A .010 bump won't effect the powder

developing loads you should have backed off the lands a few thousands instead of the manual OAL

I'm still off a good bit .093. My gun measured a OAL of 3.062 to the lands and the book says 2.955 OAL. My testing loads are at 2.969 OAL. I'm slowing getting closer but it's looking like I won't get much more due to my mag. I failed to check if the 3.062 fit in my mag when I measured the lands. Something I have to do.
