After my last test with Cor Bon some May wonder why I’m testing something form them. Well, the simple answer is, I already bought it. The more complicated answer is just because you have issues with one load doesn’t mean all their loads are that way. So lets give them another shot.
I got a five-shot average velocity of 1290fps with a high of 1302fps and a low of 1275fps. That’s a 27fps spread. Much better than the 138fps with their .357 sig loading tested last week.
The velocity from the first round was 1327fps and it penetrated to 17 inches. The bullet expanded to .58 inches and the recovered weight was 116 grains. The second round hit the block at speed of 1312fps and it penetrated to a depth of 15.5 inches. Its recovered weight was 120 grains and it expanded to .59 inches. The fragments shown in the pictures were all recovered with the bullet and came off when extracting from the gel.
When shooting through the heavy clothing covered gel the chronograph did not record the velocity of the rounds. The first round’s penetration was 15 inches, the recovered weight was 125.5 grains and it recovered diameter was .59 inches. The second round penetrated to 16 inches with a recovered diameter of .60 inches. It’s weight was 124.6 grains.
