Like to shoot & got back into .22LR last summer & been enjoying it. Today wrung out a new CZ 453 Varmint (single-set trigger) and ran through 250 rounds at the range. Photos show: CZ 453, best CZ group today (sub-MOA, I'm happy for 1st outing; lower group = me messing around), my 541S & my '46 BRNO Model 1 Trainer last winter. The latter deserves & will get better glass when I have $ to do so. All are very accurate when I do my part. Bought the 541S in 1980 & just sorted it last year to let it do what it's capable of though it needs bigger glass to really be consistent (MOA or better) at 50 yds. +. The CZ has a Nikon Buckmasters 6X18X40 Side Focus that is remarkable glass for any shooting from 50 yds. on out. The single-set trigger is a wonder. It is great to finally put time into something I started 45 years ago and let lapse!
