the velocitors do well in the 77/22, there a few companies are makin barrels for the 77/22 in the new 17hm2 i cant think of the names off hand right now but last time i checked everyone was backordered for atleast 6 months.
heres a picture of a 10 shot group from my 10-22 with a clerke match heavy barrel at 75 yards. my buddies stock 77/22 does just as good. we use the velocitors for small varmits and jack rabbits. they are great!!!
