I just checked and it's SKU 30321, the 300AAC specific version.Regaj wrote: ↑Thu Nov 26, 2020 4:36 pmjtaylor996 wrote: ↑Thu Nov 26, 2020 2:14 pmCan you tell me what QL says about the 19.2gr and 19.6gr loads?

Quickload shows your 20 gr. of H110 making 63,684 psi and 2259 fps (that's assuming an OAL of 2.247 and a total case capacity of 24.3 gr of water). YMMV, of course.
Your 19.2 gr of LilGun behind the Speer 125 gr TNT specs fine (41,974 psi and 1991 fps, using an OAL of 2.260)
I agree with the other comments that velocity and SD numbers alone aren't that great for nailing down a "best" load. You need to first have a very specific goal. Everything follows from that.
Happy to run those number for you. Before I do, you want to confirm which version of the Barnes .30 110gr. you're loading? Barnes makes a 300BLK-specific version of that bullet (SKU #30321) in addition to a generic .30-cal version (SKU #30358). When I mentioned before that your 20.0 load showed over-pressure in QL, that was using the 300BLK-specific version. Since you're not seeing pressure signs, I'm guessing you may be loading the generic version (which QL does not show over-pressure with 20.0gr of H110).
Let me know which SKU you're using and I'll run the numbers for your 19.2 and 19.6 loads.
For anyone interested, the difference between the two Barnes 110gr. bullets... the 300BLK-specific version is slightly longer.
I loaded a ladder up to the barnes listed max 20.2 with no pressure signs on the primers. Thanks!
