I bought a couple of Amend 2 poly mags to round out my build. Turns out cartridges loaded to the spec 2.26" can not be properly loaded into the magazine. If I seat them to 2.21" they function fine. Maybe it is an overabundance of caution, but I wanted to check with you experts before I ramp the pressure up on an already high-pressure cartridge. Am I approaching any kind of borderline here?
Loads are 120gr PPU HPBT, Starline brass, 29gr CE 556 and 29.5gr CE 556, Winchester WSR primers.
Unless you are recording pressure vs time, you are only guessing about safety.
That said, start with a reloading book from the bullet manufacturer you are using.
If you only make one or two small changes at most, you should be fine.
If you make many changes, even small changes, you will be in unknown territory. (Example: If you change the brand of the cartridge case, brand of primer, seating depth, and brand of bullet (still the same weight), you could easily be off by 10kPSI.
