Some recently posted pressure test results. Note; Red Dot is very similar to Bullseye in psi per gr used.
The test firearm was a Contender With a 10” barrel chambered in 32 H&R Magnum and a strain gauge affixed over the chamber at the prescribed SAAMI location for pressure measurement. The gauge was connected to the Oehler m43 and its attendant software in a laptop. I was able to measure the pressure and muzzle velocity of the assorted 32 S&W cartridges.
As a reference:
32 H&R Magnum
Federal 32 H&R 85 gr LSWC factory ammunition ran 1217 fps (987 fps out of 6 ˝” Ruger SS) at 18,200 psi.
A Lee TL 90 gr SWC over 3.2 gr Bullseye ran 1128 fps at 16,500 psi
32 S&WL;
Federal factory WCs; 12,000 psi
Lee TL 90 gr SWC over 2.8 gr Bullseye ran 1060 fps at 16,800 psi (880 fps out of my M30 S&W with 3” barrel)
Lee TL 90 gr SWC over 3.2 gr Bullseye ran 1165 fps at 19,300 psi.
98 gr cast SWC over 2.5 gr Bullseye ran 944 fps at 15,000 psi.
98 gr cast SWC over 4 gr Unique ran 1101 at 19,000 psi
Also there is considerable Pressure data (tested) with 115 gr cast in this thread.
