Tested some 40 S&W rounds today also (see other post for 223 results).
I came across some Proofmark bullets to load up some 40 S&W rounds. These are 160 grain and I was unable to find any load data for them using Titegroup. I took the load data for 165 (960-1060 fps) and 155 (1051-1151fps) grain bullets, took 1/2 of the difference and subtracted it from the 155 grain load data.
It looks like my calculations were spot on, for a change!
Proofmark 160 grain
Titegroup 5.2 grains
Very happy with these results!!!!
Everyone who reloads should get a chronograph.
