Range Report

After a 2-hour wait I was assigned to lane 9 and set my target out at 25 yards. I had a box of Federal XM193F, 5.56mm M193 Ball, 55-gr. boat-tail cartridges. I aimed at the target center and my first two shots landed 2 inches down and 2 inches to the right. That's disappointing, because it would be 8 inches at 100 yards, but at least I have some real-world results to ponder.

So rather than adjust the turrets I decided to "shoot a box": I turned the windage turret 64 clicks to the right and fired two more shots, then turned the elevation turret 64 clicks up and fired two more, then 64 clicks left windage and two more, then 64 clicks left and two more shots, then finally 64 clicks down and two more shots. I was shooting from a bag rest each time. The shots seemed to track the turrets pretty well. These turrets are 1/8" per click.

The second target was at 50 yards:

This seemed to be more like 3.5 inches to the right, or 7 inches at 100 yards.

I'm not really so concerned about the elevation because I'm so close to the target that the bullet is still rising to meet the line of sight; the scope is mounted about 2" above the bore.

The three shots above the bull were just to finish off the cartridge box.

The wind was really vicious today, so my plans to visit Clark Bros. in Warrenton had to be postponed. They have a rifle range with 25, 50 and 100-yard targets.

My goal is to use the adjustable rings to get the rifle on target at all ranges, for windage anyway, without adjusting the turrets.

I also fired eight magazines from the Ruger 22/45 with the red dot sight, and half a box from the Nagant "7-shooter". The Nagant has a formidable double-action trigger pull; I used single action. Nice shooter! Very quiet and very little recoil. Only 98-gr bullets.

The Smith & Wesson M&P 9mm compact sent some lead downrange, too, to test four new magazines (CTD has 'em in stock if you act fast).

Check out the unfired Nagant cartridge (far right) and the spent case next to it.

And I just noticed this: look at the unusual dimple in the primer. What do you make of that? 

And it wasn't just the Blaser, either. This one is Winchester White Box. It shows a dimple (at the 10 o'clock position) and a firing-pin "comma" (at 5 o'clock).

That is some BAD primer wipe! You need to check the springs, that shouldn't be happening...

Looks like its moving to unlock while the firing pin is still extended.
