Hello - a few months ago I installed a volquartsen barrel on my 15-22. It really lightened up the gun, and improved groups at 25 - 50 yards (I don't shoot past that at home).
Recently, though, my gun was running into a lot of Fail-to-Fires. 5 to 7 rounds out of 10 would be FTFs with ammo that has historically shot well. If I loaded one bullet at a time and made sure the bolt slammed home, I would usually get ignition.
In an attempt to isolate the issue I changed out anything I could (1 thing at a time, of course) - magazines, trigger springs, trigger group, extractor, firing pin. None of that made any noticeable difference. the RA-SST140 trigger was a huge upgrade over the stock trigger, though.
The primer strikes seemed to be getting too far to the rim/outside of the case. The barrel nut was still snug.
I put everything back to stock minus the RA trigger and barrel. Still no luck.
Finally, today I decided to put the stock barrel back on. I got a few (like 2 or 3) light primer strikes/FTFs in the first 20 or so shots, and then shot about 75 more with no FTFs. All the same ammo. I ran out of daylight to further test.
I don't know what happened. As I look back, though, I'm not sure the gun ever shot as flawlessly with the VQ barrel in it, but it wasn't causing 50% FTFs from the get go.
So where the gun stands right now - The ONLY non-stock item on it is the RA trigger.
Has anyone else experienced something like this with their 15-22?
