If you want quick follow up shots and don't want to go semi or straight pull then a T1x with a Sterk Swept bolt handle is ridiculously quick to cycle.
I think the T1x is easily the best rimfire on the market unless you want something specialized. A 16" T1x with a few add ons (vertical grip and proper length butt pad) is what I would go for.
The CZ 457 would be worth considering (not the 452 or 455 due to stupid backwards safety and 90° bolt throw) but the 10 round mags are too long and pointy and too far forward on the rifle.
The T1x mags a way better IMO.
