Woodcraft has pure tung oil, stuff takes forever to cure. I buy a slow denatured alcohol from Sherwin Williams for shellac, lots of coats and sanding. Boiled Linseed oil is my favorite for firearms.
We got into some ticks Friday in southern Ohio that were about the size of a large sesame seed and red. I live 3 hours north of where we hunted and have not seen this one before. Guy I was hunting with had 17 on him. They were around the top of his socks and where his pack strap went around his waist.
You're dealing with multiple angles, gravity, a strait line and that is why your P.O.I. is changing in relation to the "dot". I have mine mounted 1.75 inches below the front sight (Auto Pistol) and on a vertical plane with the bore and sighting system. The P.O.I. is on the dot at 20 feet but high closes and low further due to bullet drop. Lasers are a great tool for rapid sighting as your eye is drawn to the light. It is not a great tool for sniper shots, like in the movies. Measure the offset and angle from the bore to the laser aperture. Then sight it in with this distance and angle from your grouping. This will give you a consistent plane to base your bullet drop from. or get a couple clips and when the thieving squirrel shows his head...fill the air with lead.
The rains need to stop soon,I need to get the seed in the ground if there is going to be critters in the freezer this fall. We have clay soil here in Central Ohio and the tractors sink in it when its this wet.
