243 WSSM 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 that I can. I thought I would share this with you.

All brass was trimmed to 1.660" +/-.001":

Winchester (brass) (20 pcs): Average Weight 213.3 gr, ES 3.2 gr
Winchester (nickel) (100 pcs): Average Weight 214.2 gr, ES 4.7 gr

Please add any other relevant data you have for 243 WSSM brass, such as other brands, case neck thickness, case capacity, number of times reloaded, problems if any, etc. Loading comments or quirks would also be appreciated.

Thanks

Dave
