I thought I would mention some small things about shooting the rifle from the bench.
The recoil is not unpleasant but if you are shooting quite a bit from the bench a PAST pad or padded coat does help.
I staple white paper to the target board and then a large flat black rectangle positioned so I can save a group if I want to.
I shoot for the corners of the rectangle and align the cross hairs with the sides. Using low power scopes and thicker cross hairs you can do good work.
Make some one inch black squares to fresh the corners.
Canting is difficult to control and aligning the cross hairs with the side and bottom or top helps prevent this.
Handling recoil as near the same for each shot as possible is extremely difficult with lever actions.
If you have unexplainable fliers, your handling of recoil could be part of the problem.
A quick and easy way to reduce felt recoil at the bench and to help handling recoil the same for each shot is a wedge under the recoil pad. Brownells sell the wedges or they are easy to cut from balsa wood blocks. If you shoot offhand when hunting, pull the wedges as it will slow bringing the rifle to your shoulder for a snap shot.
Fun stuff, these leverguns.
