Last week, I up-graded my Ruger Model 77/.22 Hornet trigger with a Volquartsen Sear/Spring. I installed it in my Ruger M-77/.22 Hornet rifle; taking me around 45 minutes, as I wanted to inspect/clean other parts of the the trigger assembly. But it was a simple procedure and I installed correctly. One word of advice, if anyone installing this up-grade, a good pair of long nose tweezers is very helpful. Also please be advised that the rimfire versions of this Ruger Model are different from those chambered in centerfire calibers, like my Hornet. When removing the old factory sear on the centerfire versions the bolt release will come off too, so mind the bolt release so you don’t lose the spring that operates this part. This must not be an issue with a Ruger Model 77/.22 rimfire as the bolt release is not connected with the sear. I posted two different videos showing the difference (below)

This past Saturday, I tested my Ruger 77/Hornet and was very pleased with the trigger pull, as it reduced the pull to 2.5 pounds, and this is a full 5 to 7 pounds less than the factory trigger. I was able to hit a gulf ball at 150 yards, after re-sighting my scope. This new sear & spring also eliminated the “creep” that I had with the factory trigger. Never thought how accurate Ruger’s Model 77/22 Hornet or other versions were, but it groups very accurate now.

sweet!

Thanks. I sincerely hope the information will help those, with this type of Ruger rifle. This trigger job really made a difference in solving a common complaint about Rugers M-77/.22's.

The(rugers)do have rough triggers imho, I performed the same procedure on mine (22 mag)about 15 yrs ago and what a difference it makes. Nothing like a good shooting gun after do work on them.
Happy hunting and plinking...

I also own a Ruger Model 77/.44 Magnum, that I am considering doing the same trigger sear/spring replacement on it. The present trigger pull is not all that bad but there is some "trigger creep".

Best check and make sure replacement parts are available before you start any honing or filing. I know from experience!

Not going to hone the sear, but rather just replace the sear/spring with a new one.

Quick up-date on the trigger replacement on my two Ruger 77 rifles. It's been quite a while since posting here, but I still have my Ruger 77/.22 Hornet and with its trigger upgrade it is certainly a tack-driver. Since my last posting, I've had the chance to experiment with reloads using various powders and bullet weights. Seem that 'Lit-Gun powder is best powder for uniformity with a few other powder coming in a close second. Might also add that I also upgraded the trigger on my Ruger 77/.44 Magnum and also my Brother's Ruger 77/.22 LR. Both rifles responded excellently with the upgrades and are very accurate with a nice crisp & lighter trigger pull.

Good to know this. Videos are useful.
