We shot the years first reservist 3gun (SRA) match in Huovinrinne shooting range.
The stages were good with enough challenge and variance.
My biggest failure was not to check the barrel line in small hole, which cost 2 misses and I also shot 1 N/S on my side, but still managed to get second in overall!
( overall and stage results)
Also I should learn how to shoot pistol, as in stage 1, I shot one unnecessary extra shot to the “close range” target:
You saw right, the target in previous picture is huge!
Due to range restrictions, the targets could be set only to the back berm. This effectively prevents building a stage with close range and long range targets, but luckily the organizer had circumvented this, by applying greatly enlarged targets next to normal size targets 😀
There is always that one particular brand, type or batch of shotgun ammunition that does not work with semiauto shotguns. Some shotguns are more picky than others and even same shotgun models some individual guns cycle same ammunition that other guns struggle with.
For DIY person it’s tempting to fix this uncertainty. Naturally lapping the bolt carrier rails, polishing all metal-to-metal contacts will help the gun to cycle. With gas operated shotguns drilling gas ports slightly larger might also help.
After doing all above I still found that there exists ammunition that does not cycle reliably with my Baikal MP-153. Mostly really old 24g skeet and trap ammunition. Some may ask that why bother? Those asking that question don’t get the tickling sensation when fixing something makes things better.
Some time ago I acquired a roller cam pin to my AR-15. Gas key had to be machined to match the new round cam pin, but that was not an issue as I had planned to give my bolt carrier some diet in a form of tender milling from my trusted gunsmith. (Final weight for bolt carrier is 173 g.)
My roller cam pin had one problem though. The screw that was supposed to hold the brass roller in place had a tendency to loosen up and then jamming itself against gas key.
Original screw was completely flat, without any screw drives. I did not had adequate tools and strong enough thread lock to hold the screw in tightly.
I contacted the roller cam pin manufacturer and they offered to fix it for me. They apparently have some adhesive to semi-permanently attach the screw to rest of the cam pin.
I, being more of an DIY-guy, opted to fix the roller cam pin myself.
After two iterations I was finally happy with the solution.
It may not be the best possible steel strength for this particular application, but the brass roller leans against small bulge in the cam pin, so the screw don’t have to take any force coming from side. It just has to hold the roller in place and avoid any contact with gas key.
Time: 1 hour
Tools used: one random M4 screw, hand-file, cordless drill, hacksaw, PH2 head screwdriver and “Extra hard thread lock”
Shotgun Slug and Buckshots have nasty tendency to cost much more than most smaller shotsize ammunition. This has driven many shooters to seek cheaper ways to achieve Slugshots by modifying birdshots or using the birdshot cartridge as a base and just changing the shots to slug.
