whoa there !!!!!!!!!!!
It takes considerably less than .100" to raise pressure by 3K PSI in the 45 ACP case.
We don't do pressure, we do safe.
Easier guide: for 230g RN highly recommend an OAL of 1.240--1.265", based on YOUR gun.
Start at 1.250".
For other bullet shapes ask the specific bullet mqanufacturer, or even ask here.
200g LSWC = 1.255".
230g Golden Saber = 1.215" (just the bullet, not R-P factory loading).
250g LSWC = 1.190" (but you better be careful....)
