Two days ago I had a few friends up and did a little range testing at my place. I had just received a package of the No Excuses 460 gr. lunkers in .45 caliber. So I decided to throw a few down range at a piece of paper to see what loads to use. It was very cold and I wasn't really into it so I stopped after about 4 or 5 shots.
Anyway, I had gotten one of those sample packs from Mili-tech. So I decided to try it on the breach plug of my Encore. I snugged the plug down as I have in the past with Bore butter and copper anti sieze. To my surprise and dismay. After only 4 or 5 shots, the plug was VERY tight in comparison to the other products used and was even gritty and cruncy for the first 6 plus revolutions on extraction. The entire length of the threaded part of the plug had fouling on it. Which is something that never happened with the other products.
Mili-tech may be a good product for lubing the slide and moving parts on one of my auto pistols or rifles. Or maybe all the other moving parts of my Encore. But IMO, it's not the right product for and doesn't withstand the heat or pressures of a muzzleloader breach plug, and won't see use in mine again. If I get some time in the near future. I may do a comparison melt down test on a few different products to see at what temperatures they start to disolve and burn.
Just my observation and wooden nickles worth.
Your milage with this product may vary.
Stay Safe,
