I split the video up into 3 segments and this is part 2 of the series

Chronograph Testing
Ammunition 175gr LSWC
Chronograph 3-5 Yards Downrange
Pistols:
Para Elite Hunter 10MM - 6in Barrel
S&W 610 10MM - 3 7/8in Barrel
Ruger Blackhawk 10MM - 6in Barrel

Chronograph Data
Para Elite Hunter
Hi = 1212
Low = 1189
Average = 1202
ES = 23
SD = 8

S&W 610
Hi = 1150
Low = 1128
Average 1141
ES = 22
SD = 7

Ruger Blackhawk
Hi = 1243
Low = 1219
Average = 1232
ES = 24
SD = 9

Ruger Blackhawk 1232fps, Para Elite Hunter 11202fps, S&W 610 1141fps.
I measured the cylinder gap of the revolvers by holding the cylinder to the rear of the frame as tight as I could get it. I am amazed at the tight fit of the Ruger Blackhawk.

Ruger Blackhawk Cylinder Gap .0025 -- .003 would not fit
S&W 610 Cylinder Gap .005 -- .006 would not fit

The loads you see mentioned in the video were safe in all pistols displayed, but it is recommended that you start 3-5% lower and work your way up to be safe.

My everyday 175gr range load will be aimed at 1200FPS.

Stay tuned for part 3 with the 200gr loads.

I have not chronographed this load but I use 11.5/2400/175 cast TC bullet out of my RIA 10 MM and S&W 610 and it is accurate out of both guns. I know 2400 is not a likely candidate for the 10MM but it works well out of my guns.
