Just interested if anyone has used the shooting labs such as Oehler 43 or RSI load force which measure chamber pressure etc? It sounds like it would be a great tool to have if it functions well. I would appreciate any knowledgeable information you all have on this.

I guess the RSI one is pressure trace.

i had an RSI for a long while .. the new ones are supposed to be better. my only complaint is that the pressure strips are SPENDY

Hey Curtis, Here are some threads that might answer some of your questions.

1. Dr. Oehler comments to my questions.

2. Dr.Oehler mentions the Variances make the info approximations.

3. How a M43 does compared to good old, never fail, always reliable - CHE.

Best of luck to you.
