The ballistics of the 5.7 are not too much more than the 22 Hornet.
When I saw the round i thought like everyone else it would be a neat little varminting round.
Also thought a 19 Badger (30 Carbine necked to 204) would be a neat round to chamer a 77/22H in.
I have a 77/22H originally I had a really big scope on it and was not impressed with the groups, went to the Hornady 35 grain bullets and the groups closed up. At first i just thought it was the hornet and having problems makeing a group at 100 yards.
One of the guys i met here met me at the range with his 22 Hornet handi and he was making quarter sized groups with his reloads.
Changed the scope to a 3-9X38 Weaver V and the 46 grain bullets tightend right up and the 35 graines opened up a littel but not bad.
Krochus, is there something with your rifle that is causing a problem, Stock touches the barrel, barrel wedge loose, any number of things.
Have you sent it back to the factory with a target?
A buddy had a Ruger 77/17 that would not shoot at all. Sent it back and found out that the barrel was a 204 Barrel.
just wonder if something goofy was done and you ended up with a 243 barrel on your 22 hornet. That would cause some accuracy problems.
