Demo videos of IPSC

I have though for a while to do some sort of recap or compilation from the vast amount of un-edited shooting videos. I finally managed to get myself to do it, as I’m instructing an IPSC beginners course next weekend and these kinds of demo-videos will be a good addition to the rule-books and slideshows.

Demo 1 is about different start conditions: loaded, chamber empty and unloaded (or “Option 1 through 3”)

 

Demo 2 has reloads with pistol, shotgun and rifle

 

And the final video has different “stage challenges” and one example solution for them

 

Ps. I’m truly sorry about the few scenes that were apparently filmed with a potato..

Aimpoint Micro H-1 vs Bushnell TRS-25

Here’s a little picture comparison between the Aimpoint Micro H-1 and Bushnell TRS-25 micro red dots.

The first image depicts the difference in light transmission: cheaper TRS-25 filters a lot wider band of red, resulting in a very bluish image through the sight where the Micro H-1 appears almost natural.

NEA15-22 part VI -hammer time!

The manufacturer seen some of the pictures and they insisted that the non-milspec hammer/trigger was the issue causing light strikes.

If I recall correctly, the original hammer had similar light striking issues and I am pretty confident that the issue is caused by the recoil spring guide that makes contact with the hammer, so I checked the original hammer:

Original hammer wear after about 200 rounds
Original hammer wear after about total of 200 rounds (the other side does not have similar wear)

NEA15-22 part V – the culprit?

My previous assumption for failure-to-fire was, that the bolt didn’t close properly (possibly due to the overly tight extractor) and thus some of the power from the hammer was used to close the bolt and then there was not enough force to ignite the primer. Now it seems that the power from the hammer is lost somewhere else..

I previously noticed some wear on the recoil spring guide / bolt weight, but didn’t find what would have caused it or if it was there to start with, so I took a magic marker and painted it blue. Now it had new markings and some of them even pretty deep.

NEA15-22 part III -tale of a crappy bolt

The plot thickens..

I had cleaned the rifle, done a little polishing and then of to range for test firing.

First 50 rnds (2 mags) seemed to be discharged without any problems, but then the problems started. Around 20% of the rounds failed to ignite on first try, but most ignited on second try, after being put back to magazine and re-cycled into the gun.

I collected some examples of fired casings and also some non-ignited rounds to check the firing pin markings. Then I also noticed that the first 50 rounds were not so successful and had included some bulged and deformed casings.

Some fired and deformed casings mixed with some failure to ignite rounds
