Yesterday at the range started out on the main firing line, where the BG380 digested another hundred rounds of the Fiocchi 95gr FMJ from Lucky Gunner without a hiccup of any kind. That brought the total rounds fired to six hundred. I then adjourned to the pistol bays with my chronograph and two boxes of JHPs from the assortment I had on hand around the house.
First up was
Sig Sauer's 90gr V-Crown JHP. The ten-shot string returned these numbers:
LO: 897.6
HI: 946.0
AV: 917.0
ES: 48.41
SD: 15.09
This is about 60fps slower than the box flap velocity claim, and gives an average muzzle energy of 168 ft/lbs. Recoil seemed milder than most of what I'd been shooting, too.
Next was ten shots of
Winchester's 95gr W380D "Defend" JHP:
LO: 837.5
HI: 933.5
AV: 886.8
ES: 96.05
SD: 27.89
That's also 60fps below the claimed velocity, and works out to an average of 166 ft/lbs. There was noticeable muzzleblast in the sunny, noontime pistol bay, which makes me wonder what it looks like in the dark. I'll need to look into that.
Then I went back to the main firing line to shoot both of these loads at ten yards for groups, just out of curiosity.
When shooting the Sig Sauer V-Crown, I had another light strike. This was the hundred and twenty-eighth round of the day, #628 of the test. The round functioned normally on the second attempt.
Because I'd used an extra round of the Winchester due to a chrono goof, I only shot one five-shot group with it. Just like the W380T 95gr FMJ, it printed high and left of the bull, into a group measuring 3.4". The Sig tended more towards straight left, with the better of the two groups measuring 2.9" and the other only a couple tenths bigger.
That's 640 rounds in the books with no cleaning or lubrication. There have been three light strikes on primers (#
140, #
357, #
628), but otherwise the pistol has gone
through the complete cycle of operation with each pull of the trigger.
1360 rounds to go.
