Lipsey’s Ruger Blackhawk 10MM: 135gr Chronograph Test: Part1

| November 26, 2017 | 0 Comments

I split the video up into 3 segments and this is part 1

Chronograph Testing
Ammunition 135gr Nosler
Chronograph 3-5 Yards Downrange

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 = 1546
Low = 1503
Average = 1527
ES = 43
SD = 20

S&W 610
Hi = 1439
Low = 1179 Not sure what happened here, I feel like this was a misread by the chronograph. The round felt like all the others.
Average 1377
ES = 260
SD = 98

S&W 610 Remove the low shot
Average = 1417

Ruger Blackhawk
Hi = 1608
Low = 1527
Average = 1559
ES = 81
SD = 34

If nothing more this data tells me maybe my Hornady LnL AP Powder measure is not as consistent as I would like for it to be, though good enough for my range time. There is a reason I still load all of my rifle data on a single stage and trickling my final load.

Ruger Blackhawk 1559fps, Para Elite Hunter 1527fps, *S&W 610 1417fps.
I measured the cylinder gap of the revolvers by hold 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

* S&W 610 Denotes Error correction by eliminating extreme low shot.
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 135gr range load will be aimed at 1400FPS.
