40 S&W Brass Data

[DR Owl Creek]

This is data I have accumulated over a period of time, while trying to work-up the most accurate and consistent loads I could. I thought I would share this with you.

Federal (100 pcs): Average Weight 68.3 gr, ES 2.0 gr
GFL (Fiocchi) (50 pcs): Average Weight 66.7 gr, ES 2.3 gr
Starline (30 pcs): Average Weight 64.8 gr, ES 1.1 gr
Speer (50 pcs): Average Weight 66.2 gr, ES 5.7 gr
Winchester (100 pcs): Average Weight 70.7 gr, ES 5.9 gr

Please add any other relevant data you have for the 40 S&W brass, such as other brands, case neck thickness, case capacity, number of times reloaded, problems if any, etc. Loading comments or quirks would be appreciated too.

Thanks

Dave
