I bought this not too long ago for the girls, it shoots 55gr. the best out of it's 1:9 twist barrel. I tried various bullet weights, 55, 60, 62, 69 and 75gr out of the hot n cold barrel, it didn't matter, 55's did the best all the way around.
But if Ruger has truly fixed their Mini 14 accuracy issues that would be a great little plinker. Aside from the flat top AR being easier to mount a red dot sight to, the Mini 14 might just be the perfect little rifle for small statured people.
