Isn’t droop for break barrels? I don’t think hw97k has droop?
Both my 97K and 77K barrels are pointing down and left or right from the dove tail. So If mounting a optically centered scope and then taking a shot at 30 yards, it would hit around 6" low and 5" left
give or take a few inches..lol.
You either bend the barrel or use some kind of adjustable mount to get it close to zero, unless you want to use a lot of your scopes vertical and horizontal turret adjustment.
You will get the best performance out of your scope by keeping it as close to optical center as possible.
On my 97K and 77K as well as my prosport I use a UTG picatinny rail and low rings. The prosport was close to being dead on. With the 97K and 77K I used burris signature zee rings with eccentric inserts that allow vertical and horizontal adjustment. It can be a time consuming process, but only needs to be done once.
There are many mounting options available. In the past I've used sportsmatch rings, UTG rings mounted to the dovetail and they work fine. Then switched to signature zee rings (picatinny) and used picatinny to dovetail adapters, they also worked, but more fiddly to set up.
Now all my rifles are using the UTG pic rail and low pic rings. Here the 77K set up with signature zee rings on the UTG pic rail.
The rail has stop pins as well, and I use them.
Here's my prosport with Athlon rings on the UTG pic rail.
