Title: COP 155gr, Speer GD 200gr, Georgia Arms 180gr and a couple other ones
Post by: Intercooler on September 27 2013 05:50:36 PM MDT
   Tried all of these out today using the new Elite Limited 4.75".

Armscor 180gr FMJ 1158, 1129, 1149, 1144, 1140. Average = 1144 FPS/ 523 LBS

Speer 200gr Gold Dot HP 9.2gr's Long Shot 1235, 1248, 1211, 1252, 1239. Average = 1237 FPS/ 680 LBS Nice!

Georgia Arms 180gr FMJ 8.4gr's Long Shot 1221, 1219. Average = 1220 FPS/ 595 LBS. I believe this is their +P version and very nice!

Rainier 180gr Hex-Plated HP 10.8gr's Blue Dot 1241, 1267, 1263, 1263. Average = 1258.5 FPS/ 633 LBS. About the perfect full-power target round.

COP 155gr All Copper HP 11.0gr's Power Pistol (Buffalo Bore load) 1422, 1435, 1456, 1413. Average = 1431.5 FPS/ 706 LBS. Really happy with this level of performance and would love to see them in gel!

Underwood 180gr TMJ 9.8gr's Power Pistol 1303, 1309, 1311, 1301, 1304. Average = 1305.6 FPS/ 681 LBS. Underwood 1300!

Very nice report, like what I see!  8)

Were the 9.2 gr LS loadings of the Speer 200GDHP better at this level? compared to the 9.4 from the earlier test?  ???

  Average of the other load 9.4gr's of Long Shot was 1289 FPS/ 738 LBS. I'm going to stick those in the "discontinued" tab.

The Buffalo Bore 155's gave just a tad higher velocity but is that due to the large bullet and compression of the powder?

Yes and maybe because the brass was worked some from pulling and re-seating, the casing may have had a slightly less grip on the bullet, I taper crimped them back into the original marks (crimp cut into the bullet) although the bullets where fairly secure and didn't exhibit any movement.

Did everything run without issue?

Yup. All my Witness pistols eat like Hungry Hippos.

  It's funny I had a guy to the right of me shooting an AR .223 pistol (LOUD) and was barking off some 10mm and he asked what that was. He said I can really feel it  ;D

I wonder if it was the Loud Shot or Blast Dot he was feeling?   ;D  Could have been the Power Pistol!  :o :o
