Thread: My first load development

@Remmodel7 Unfortunately my version of Quickload doesn't have the 123 ELD-M, only 123 gr A-Max and 123 gr SST.
I don't have a Hornady manual so didn't know the expected velocity.
Hodgdon and ADI only list loads for the 123 gr Sierra HPBT. When I tried to replicate their loads in Quickload it gave much higher velocities than either the Hodgdon or ADI data.
That's unfortunately the nature of Quickload. Sometimes its spot on other times you have to frig with it to match your real world results with the results displayed in QL.

Using the 123 gr A-Max (SST gave very similar results) the pressure for a 26 gr load of BM2 is predicted to be 48923 psi versus the Pmax for the cartridge of 52000 psi. Again, because I have no Hornady manual the predicted velocity was not able to be compared to the manual velocity.

The calculated velocity drop for a 20" barrel over a 24" barrel is 86 fps (123 gr A-Max).
