How I stopped worrying and learned to love the Mini 30

How does the trigger and hammer spring affect feeding? She cycles and fires 100% as is, but I'll probably order myself a kit just to have on hand. If anything, after smoothing up the engagement surfaces with valve lapping compound the pull is almost too light for hunting, heavier springs would address that.

Kit comes with hammer, triger and main spring. The main spring is much stronger; i find the factory ones have a hard time picking up a round off a full mag and can require a recock to knock the first round free of the feed lips, especisly off polymer mags. Thus issue gets worse after break in.
With the wolf triger group springs the triger breaks a lot more crisp and you get a much more solid strick on the primers.

The gun just runs nicer it's worth $20-30 you pay
 
2" would be tough IME, 3" for sure with better than surplus ammo. Those groups above were with cheap Chinese surplus from Tradeex. The single group is 4", the best one is 2". Oddly, shot with a blazing hot barrel. I wasn't using the best targets, they're my 50 yard M1 Carbine ones, and they were a bit hard to have a consistent POA with a 3 MOA red dot at 100 yards. Could probably shave a half inch off that with something I could actually see at that distance... But they're pretty representative. 4 MOA from a self loading rifle shooting x39 is about my benchmark, that's about what I'd expect in terms of average accuracy. Everyone would be all over an AK for the price if they were still NR here, and they won't do any better. If I need more precision there's always my bolt rifles.

I had a 581 Mini 30 that was replaced under warranty with a 583. I put the 583 in a hogue stock and with Barnaul 123gr the best group I've got so far is 2.25" at 100 yards with a 1-4x Bushnell AK optics scope. I agree that 2" is tough but probably doable. The previous 581 series couldn't seem to do better than 3.5" regardless of what I used for ammo.
 
So, all the reports of the mini 30 not firing surplus were exaggerated? Or is it just the 583 series that seems to be ok?
 
I'm really interested in one of these, I have heard that the bore diameter is .308 where surplus ammo is closer to .311 do to inaccuracies in the the Soviet rifle production. I sent a email to Ruger to confirm.
