I was in the weapons testing business for the gov't and speaking from a wide experience I can tell you that before you choose something for a certain use make sure you do not cause another problem.
For instance some "miracle lubes" are great for preventing rust and that is fine. Some are great for cleaning and that is fine and some are great for lubrication and that is fine
BUT........................................................
Before you settle on one next time at the range for a long session before you leave shoot four five shot groups at 100 yards, then use your miracle juice in your bore and let it sit there while you change targets.
Next repeat the same four five shot group test and see if there is any change in your group sizes.
Some of these miracle concoctions are actually too good in the lubricant application mode and your bullets will tend to override the lands at first destroying accuracy until it is burned out to where the lands can control the bullet as designed.
If you are a tin can assassin etc you won't see the problem but if you are a serious shooter wanting peak accuracy you best take a looksee before you use some of them.
I use Ed's Red (a concoction you make yourself) which is 1/3 K1 Kerosene or off road diesel,
1/3 Mercon Dexron Transmission Fluid, and 1/3 mineral spirits (paint thinner) which is best I have found. I have left it stored for 14 months in barrel and borescoping after storage found it still wet and still in place and not gummed up. I make it two gallons at a time and have it in three one quart spray bottles I get at Home Depot and in small bottles as well.
I have found on the first shot from a cold, clean wet bore it will be slightly off but settles down quickly to business.
Anybody ever seen a bad bore in a Swiss surplus rifle as received? Never heard of one. The Swiss have used grease as their bore cleaner since 1890s. They apply grease to bronze brushes and brush their bores as soon as they get off the line, then later use patches and leave them with another greased bronze brush stored. They ran about 45 rounds a year through them if they were not a shooter and more if they were. I just got one that has been stored since about 1985 and borescoped it carefully and bore is perfect. The guy that had it issued to him was born in 35 so he would have had it issued about 1953.
I have used Grease Auto and Artillery and Grease Aircraft WTR for cleaning bores. Both are synthetic. No wild shots have been experienced. You might give this a try as well.
As soon as you fire last run run bronze brush through bore about five times till you see the carbon dust subside that comes out the muzzle. Then run greased patches (with above) through till they come out clean and leave bore lightly greased from the patch. As indicated no wild shots experienced.
