Crown look okay.
Just shot it this morning. 1.2 inch groups at 100 yds with 20 gr Hornady
The 15.5 gr. Hornady shoot nickel groups.

Id rather the 20 grainers shoot better for the longer shots but until I figure how to improve their accuracy The 15.5 will have to do.
Ill keep playing with it till cold weather then maybe trade it on a Ruger 17 Hornet. Maybe they will handle the heavier bullets differently.
Thank Johnhenry
