I have two Brnos, a 21H in 8x57 and a 22H in 7x57. Both have very long jumps to the lands. Good thing both have .30-06 length mag boxes because I use most of that length. They shot very well when bullets are seated appropriately.

My experience with Prvi ammo is limited but I recently built a customer a pair of 9,3x62. He wanted the rifles regulated to shoot the Prvi 285 factory loads since he was not a handloader. Both rifles shot sub MOA with open sights at 100. I tried the same ammo in a 9,3x62 I built for myself at the time and it liked the ammo too. YMMV.
