That's not bad at all for a .22lr at 60 yards. - it's so easy to just pick out a good group with a "my .22lr shoots inch groups at 100yds" comment. In reality I think your 1 1/2" is much more the norm, when all shots and all groups are measured. Also, when comparing groups it's always nice to have some sort of standard - Plopping a cornflake box down the field about a 100 paces away and measuring the group with your thumb (discounting the cold barrel shot and the one you pulled) is not exactly comparing oranges with oranges.
These two 5 shot groups were shot at 68 yards with my Sako Finnfire (Shilen match barrel) both about .5 moa - However - this is just two groups out a total of 6 x 5 shot groups on the card, the rest were over 1 moa and would have ended up at around the 1 1/2" - I find regular sub 1" .22lr groups with a sporting rifle quite a rare beast and even with a quality match rifle and ammunition it's not that regular.
