A friend had his chrono at the range today so I played a little with some carry ammo. I wanted to see the actual MV difference between standard velocity Gold Dot 124s and +P. I shot 5 of each from a stock MkIII HP.
Standard(fps):
1180
1183
1198
1181
1179
Avg. 1184

+P(fps):
1227
1221
1249
1234
1246
Avg. 1235

Consistency was acceptable, but I was a bit surprised with the MVs. I thought the regular stuff would be a bit lower with a greater difference between the 2 loads. It is my prefered carry load, so I guess I'll be happy with whichever I happen to find the most of. Currently have 1 box of the +P and 3 of the reg.

Going back over some hipowersandhandguns articles, I noticed that Stephen's MVs for the Gold Dots were significantly lower than mine, both standard and +P. Could be my HP or the chrono used, but now I'm curious. If anyone has the rounds, a chronograph, and a Hi Power, let me know the actual MV you get for these rounds (124 grain Gold Dot HP).
Thanks in advance.

Hello. It can also vary with the ammunition from lot # to lot #.

Best.

True.
I'll take my current lot #s to the next area show and try to get same rounds but different lots. I wouldn't have expected such a big difference between your tests and mine, but it is possible. Should be interesting to see what I get the second time around.

Hello. I've also noted that sometimes different maker's bullets of the same weight can sometimes have surprisingly significant differences in velocity. Some barrels may be optimum for use with something having conventional gilding metal while others like the greater copper content jackets as per the Gold Dot or Winchester's Ranger ammo. It's sort of a
roll of the dice thing as to which likes which. I look forward to your information and appreciate your contributions.

Best.
