So you only shot a couple of groups with each different type of ammo? That would likely explain the consistency issue.

Sorry should have explained it better. I shot 10 5 shot groups with each ammo. Cheers.

Ah, fair enough. The minimag group doesn't look too bad. I use them in my Winchester 9422. My old 452 also liked most Federal ammo. You're always going to have a little bit of inconsistency with 22 hunting ammo as what you're paying for with the more expensive match ammo is tighter tolerances and less inconsistency. I don't know if you've tried the SK yet, but I don't know many (if any) Brn/CZ rifles that don't like it.

A lot of the USA based advice talks about an "ACE #144 spring" or similar for 20 cents or such. I have no idea where to source something like that. I don't have an ACE Hardware store in Western Australia. I do know the Yo-Dave kit was the best $18 I've ever spent on a firearm improvement - ever! Even if I only actually used, maybe, $2 of actual parts in the kit. It completely transformed my rifle from "meh" to "wow!".
YMMV, JIm

Agree with Flyer, it's not the trigger weight so much as the gritty creep I had in the "take up" phase of the trigger pull. Eliminating that creep completely changed the rifle. That said, many don't have that issue and have great triggers out of the box. I wasn't so lucky but I was able to fix the issue cheaply and with minimal effort and skills. YMMV
In any case CZ are the best value rifles for the money in my humble opinion.That's why I bought more in different calibres.
