I am in the process of switching all my big game hunting ammunition customers to Barnes Tipped Triple Shocks.

If you have not signed up for the Barnes University, an on line loading and shooting course offered to those interested. It cost about $50 if my memory serves me correctly. I have been shooting and loading ammunition for over 45 years and I learned a lot.

With the action right side up, when the action is cocked, clearance at the rear bridge of the action combined with the angular interface between the cocking piece and the trigger sear causes the back of the bolt to rise, taking the top lug off of its seat, and when the trigger releases the cocking piece, an the reset force on the sear continues to keep the top lug off of its seat as the pin falls. This is the primary reason that bolt clearances are considered important for best accuracy. With the action inverted, the back of the bolt is held down by the trigger, and the front by gravity, so that both lugs are in contact with their seats, an obvious advantage when the extremes of accuracy are being pursued. I am not sure that this sort of testing would show the difference, if a custom action was used, but for match work, it might, in a good tunnel.

Hitting a trigger even on a machine rest can not be a good thing for accuracy

As civil82 mentioned, after doing it all week, you soon get very bored. I can testify that proof work can be extremely monotonous and boring. I have firsthand experience of it and the stuff I was testing were artillery, tank guns and mortars! I even fell asleep a few times, neither good as I head butted an industrial keyboard made of rather thick and hard ally and the other time I was woken up by a tank gun firing with no ear defenders on… ouch!!!!

The upside-down trigger orientation means nothing, it is just more convenient for the tester rather then bending down and reaching underneath for every test fire.

Not sure about the accuracy of those bullets.
The screen showed a distance of 202 feet.
Target grid size was 0.5 inches and the group shot was a whopping 1.2 inches.

Now from a machine rest and accurate bullets, I would have expected much better.

I agree that this would be a dream job, but after test firing all week, I highly doubt that I would want to go to my local range and fire my own rifles after dealing with it all week.
At any rate, thanks for the write-ups!

Roy,

That’s a good question; maybe it’s to settle the powder evenly so there is a consistent air to powder volume ratio?

That is really impressive software and equipment, whatever it is. Some ranges have electronic scoring for highpower matches, but this is a new one for me, too. I haven’t heard of one that measures groups automatically.

When I win the lottery, I’m putting one of these ranges in my basement.

Notice that he taps each round “5” times before loading…..I wonder if he knows something I don’t!!!!!

I wonder what type of electronic equipment is used…the video was very careful not to show the left hand section of the screen.It appears that there is a chronograph and Triangle electronic target system in unison.Very cool

Could I get the use of the range for a day? PLEASE

AccurateShooter staff,
Thanks for this write up! I’ve been doing my own research on bullet manufacturing, but not turning up very much information. This was helpful, as well as the link showing the other videos and other processes involved with making bullets. Imagine being the lucky guy who gets to test fire ammunition all day, what a dream job. Hopefully I can get into the industry myself once I’m out of school, and into one of these positions. Keep up the good work!
