The trigger frequently fails to reset when using Aguila ammo. It ejects the previous round and feeds the next round with no problem. I have thoroughly inspected, cleaned and lubed everything. Today, it failed 5 out of 25 rounds with Aguila Super Extra 40gr 1255 fps copper plated round nose. I had no failures with CCI MiniMag 36 gr 1260 fps copper plated hollow points.

I have better consistency with the MiniMags too. My Aguila group was about 3 inches and the CCI group was about 1 inch, shooting at 25 yards, seated with a bipod.

More details, please. Describe what you mean by trigger not resetting. Is the hammer following the bolt, not being cocked at all, or is it staying cocked, possibly stuck on the disconnector?
 
The bolt is not coming back far enough to cock the hammer. The trigger is dead.
 
My experience with Aguila and the 15-22 is mixed at best. Some batches work fairly well. Some area weak and inconsistent such as you experienced.

The only rimfire I will buy nowadays is CCI, Even their cheapo Blazer works well for me when other brands fail. Federal and Remington are inconsistent, Winchester & Armscor are just plain bad. In my experience, that is.
 
That’s odd, I have had no problems with Aguila. It’s not as hot as MiniMags but should still operate the action. My 15-22’s run like a top on CCI SV, definitely not as hot as even lower power HV ammo. I would look at the recoil spring and guide for problems and be sure the bolt has some lube where it rides on the guide rails.

My experience as well.
 
OP, I wish you were close by, I would loan you a CMC trigger to drop in. That would eliminate one variable.
If you are planning to keep the rifle and shoot it, a CMC or Palmetto’s knockoff is a very good investment. Either one is around $100 on their daily deals.
 
I've got prolly 10K rounds of Aguila Super Extra 40gr with the rare FTF or Stove Pipe. Before that I was using CCI Mini-Mag Target 40gr. It even had the occasional failure. Although cleaner than the Aguila. Since then I upgraded to Volquartsen Competition Bolt Kit. https://volquartsen.com/inventory_configurations/6996 The kit includes a Diamond Like Coating (DLC) Bolt and an ejector which is designed better. The brass flies out 20 to 25' where as it was 6 to 8' previously. And since then I have had zero malfunctions thru at least 5K rounds of Aguila Super Extra 40gr. FYI: I have the Performance Center 15-22 which is supposed to be even more picky with ammo. If you have never had a DLC Bolt you will love it, I have upgraded all my AR15s BCG to DLC. Cleans with a soft cloth only. Yes, I've got a lot of use of my 15-22. Go to the range weekly running roughly 300 to 500 rounds each time. I did have my trigger break early on. Prolly after the first 2000 rounds there about? Called S&W, they sent me an RMA. Shipped it to them via FEDEX. They replaced the trigger and shipped back. Total turn around was about 3 weeks. When I say it broke, I mean the hammer snapped! Pulled the pins and opened it up and the tip was just sitting there.
