I've always wondered why people will accept the fact that oil can leak from an oil bottle, and thus cause a mess, and then proclaim it as a good hinge pin lube? If you believe the drop of 3 in 1 you put on the pin is still there after the last 100 rounds you shot at the local clay pigeon emporium of choice, in 85 degree or so temps, you are sadly mistaken. Oil, you see, is a liquid. Liquids, by definition, flow. Usually, into the wood at the front in this case, which, unlike a solid metal hinge pin, is happy to warehouse runny oil for you. End of story.
One fact missed by most is that a hinge pin is a perfect example of a part that is stress loaded, and unlaoded, at the shot, and further exposed to radial movement, with further loading and unloading, depending on what type of ejector or extractor mechanism is present. If it was an industrial application, the pin would be drilled, and have a lubrication groove (anulus is the correct term, but, I'm just guessing Prep H isn't an EP, or extreme pressure, lube) around that, with a zerk on one end, and call for lubrication at the beginning of an 8 hour operating shift.
If you aren't using an EP synthetic grease, you are missing out on a superior lube that will stay in place in every weather condition, hot or cold, you can expose the gun to here on earth.
That way, you can leave the decorative oil bottle in your case empty, and avoid the mess, as well.
Best,
Ted
