Well scoped the 5mm preparing for this, got it on paper at 25,50 then punched 2 groups at 100 the old Rem probably won't do it but the new stuff punched a .754 so I think will be in good shape.
I also shot the CZ 22 in between, checked zero and warmed up barrel with 5, then shot a .57 to make sure everything was working. Then did the challenge and averaged .751 ( shot with non-match hv ammo

) hopefully photobucket works for me.
The 17 had a couple just over an inch a few weeks ago, got another kind of ammo to try on that one.
