I have a Leupold compact 6x scope mounted on my Marlin 357 lever gun. This will be a serious steel target and plinking gun if I can get it to shoot cast bullets. My range is only 200 yds, and I found out years ago that my ground hog rifles got boring shooting steel at ranges which did not require any sight adjustment from point blank to 200 yds. The 357 rifle ought to be just the thing. Besides, I found out about Marlin's problems in time to find an early 357 carbine and I love the rifle.
The problem with the scope is that the adjustment knobs are extremely hard to turn. The coin slot is not deep enough to get a good grip on the knob. The elevation knob is a good deal tighter than the windage knob. Both knobs seem to move the crosshairs properly once they are turned. I have thought of using Kroil or some other solvent on the knobs, but I wonder if that will harm the internals if it seeps down to whatever is binding the knobs? Years ago there was some fellow who did a great job installing klick-adjustable knobs and custom crosshairs on leupold scopes, but I have forgotten his name and I suspect he has long since retired.
Any thoughts or ideas? Thanks in advance.
