The charge weight is MAX charge, reduce by 10% to 15% for START weight.

I would also take your barrel off and do a plunk test It sucks to make a few hundred up just to find out that the OAL is just a bit long
for your pistol

Set the seater up so they all fall between 1.130 to 1.135 OAL. If they pass the plunk test, which they should, you're good to go.

That's what I use for the RN, but I believe the OP has the flat-point version. Is it favorable (or even possible) to seat the FP that long?

Berry's 9mm 115grn RNFP ... What should my C.O.A.L. be?

Titegroup and BE-86

Below is RN vs RNFP bullet comparison. Titegroup and BE-86 are dense powders so you shouldn't have powder compression issue with deeper seated RNFP bullets. While RNFP bullet loaded to 1.070" will fully chamber and spin without hitting the rifling of my Lone Wolf barrel with no leade, I usually use 1.060" as my working OAL. Of course, 1.070" works fine in my KKM barrel with longer leade.

Set the seater up so they all fall between 1.130 to 1.135 OAL. If they pass the plunk test, which they should, you're good to go.

As to RN, I usually use 1.130"-1.135" but with less dense fluffy powders, I use longer 1.150"-1.160" to not compress the powder charge.

Good catch, no, I misread that.

Great catch, I also miss read the OP’s original message.

when I am new to a bullet I seat it long were it won't plunk, and then I shorten the col until it does. Now I know the max col and I find a col that functions in the pistol and magazine that is shorter than the max. using dummy rounds. Now I crimp the dummy rounds and run the through the pistol as if they were fired, I measure and check for set back if there is no set back and they feed well I now have a workable col.
