ar-comp ladder question

[mdram]

i have been researching to develop a ladder for ar comp and 123gr sst
speer lists a 120gr with 25.3gr giving max pressure
quickload and grt agree with this

i see people posting 27gr loads or higher without pressure signs

i was thinking of a 10round ladder with .3gr increments
just wondering if 24gr was too high a start, or not high enough?
will be using new hornady brass with federal 205mar primers

edit: will be from an ar with 20" bartlein barrel, pf bolt, toolcraft carrier

Might mention what you are going to be shooting it out of, the advice you get may vary based on that. You will get away with more in a bolt action.

hhhhmmm. maybe i will do one long ladder, .3 gr. single charge just to find the max pressure i can shoot safely
start @24 take it to 28 or 29

I too am trying to get to 2450 or 2500 with AR Comp and either 120g Gold Dots or 123g ELD Ms 27.6g I think is my stopping point as accuracy fell off and ejector swipes became noticeable on new Hornady brass and CCI 450 primers
