Done.

Here’s an update:

Brimstone did a marvelous job on the Mini 30 trigger, reducing trigger pull from around 5 lbs to 3.25 lbs.
I have a Mini 14 for comparison, and the new trigger is smoother. Brimstone was quick, inexpensive, and easy to deal with. They did the trigger work exactly as requested.

Attached is information from Brimstone’s website pointing out that Mini’s have a two stage trigger.
The 3.25 lb pull is measured assuming the shooter makes a single smooth pull through both stages.
It is very nice. After shooting the Brimstone trigger, the unmodified Mini 14 trigger then feels heavy.
Brimstone Mini Trigger Info.JPG
If instead of making a single smooth stroke through both trigger stages, the shooter instead slowly pulls the trigger to the end of the first stage, delicate hands can feel the point where only slight additional pressure is needed to complete the trigger pull through the second stage.

At that point, additional vigilance and care is required as it takes very little additional pressure (1.5 lbs) to cause the rifle to fire. It feels a bit like the very light ‘set trigger’ on the CZ527. In the field before hunting with the CZ, I will dry fire 3-5 times using the set trigger to relearn the point where the trigger will fire. I will do the same with the new Mini trigger.

The trigger stop screw is a nice feature, preventing unnecessary rearward movement of the trigger after the rifle fires. They say it gets the shooter to the next shot quicker and with less rifle movement. I like it.

After I do more shooting with the Brimstone trigger, I will do some accuracy testing to compare groupings previously made with the unmodified trigger.

Hoped for accuracy improvement was the reason for the trigger job.

I suspect that the trigger group from my rifle will be making the journey to Brimstone. Thanks for the report!

While researching how horizontal stringing might be caused by flawed shooter technique,
found this gem regarding the connection between trigger pull and accuracy.
The poster gave credit to Varmint Al:

"Now, test what your trigger pull is doing. You don't need ammo for this. I like to start with the gun cocked and the safety on just so you can see how much your cross hairs move when you pull on the trigger. Get set up like you're ready to shoot and aimed at the bull. Now squeeze the trigger, while keeping a very close eye on the bull and the cross hairs. Did the cross hairs move? Then expect it to move when you shoot for real. "

Here's a followup after shooting 100 rounds with the Brimstone trigger.

I like it.

Have a couple of old ammo cans filled with China Sports soft point from the 90s.
Turns out that my Mini 30 likes it and shoots good groups with it.

Spent last Saturday at the shooting range hitting 4 1/2" orange clay targets
set up on the 100 yard berm. Lots of fun.

It took a few rounds to get accustomed to the light second stage trigger break.
But now it feels quite good.

Make certain you clean well after using that Norinco (China Sport) ammo.
Buddy of mine had his Mini14 seize up after using some of that stuff back in the day.
He ended up having to cut off the gas block in order to get the bolt open the next day.

I had Brimstone clean up my Mini14 trigger several years ago, very happy with the result, service was great too.
