so I finished testing on some 124g speer gold dots. I generally use 124g berrys round nose for training and practice and wanted to match the loads for training purposes.
bullet length measured with micrometer
gold dot 0.5588
Berrys 0.5890
Diference 0.0302
listed COL
Gold Dot 1.120
Berrys 1.160
Difference .040
In theory if I seat the Berry's to 1.150 it should put the base of the bullet in the same place in the case giving me the same case capacity if I am thinking about this correctly.
The loads from Speer are a bit higher than published in some other manuals, but I worked them up and feel they are safe in my guns with the gold dot based on my testing. So in theory if I work this load up from start using the Berrys bullets with the Speer data and modified seating depth it should be within safe ranges as well as I am using the same case capacity right?
Or am I thinking about this wrong? It there more involved, am I over simplifying this? What else should I be considering?
