.45 Colt Pressure Data
I am not sure if I posted this before. If I did just ignore this. 
Years back John Linebaugh helped me get .45 Colt loads pressure-tested at Hodgdon's in their pressure barrel. John had built the pressure barrel for them and had access to it whenever they weren't running tests.

Saved and filed. Thanks!
Important ... not shown on the data sheet
The 300 gr. #45191 bullet was seated only deep enough to crimp into the top grease groove.

Thanks, I love reading pressure data, interesting to see the pressure jumps with slight powder increase. One of the reasons I like older reloading manuals, they included pressure data on the loads.

Thanks for posting that. It’s surprising to see the bullseye pressure so high, especially for the velocity. MTter fo fact, I don’t see any that are under max pressure for standard 45 colt loads. I know red dot and bullseye are pretty close and ,y standard lighter .45 colt load is 6.0 of red dot under a 454424. I wonder how it is for pressure.
