reduces copper fowling and makes the barrels clean up easy. extends barrel life and and in some rifles accuracy will improve, iv tried molly coated bullets in 3 of my rifles, only 1 likes em (accuracy wise). you'll lose velocity due to reduced pressure caused by the bullets moving down the barrel with less friction (see longer barrel life). usually you can bump up the powder charges enough to compensate for the velocity loss but you risk loosing accuracy. bottom line, molly did nothing for me and i found myself chasing my tail with all the above said. id really only consider it a benefit if i was shooting 1000 rounds or more per month on prairie dogs in montana.

If you shot a lot like wrangler said it helps but other wise I dont see what they do over regular bullets. I had a 22-250 and shot lots of grave diggers and used the moly bullets, you have to be careful loading them becuase if you scratch the coating off youre groups will open up. I put well over a thousand rounds down that gun in a summer and when I sold it to a gun smith he ask how much I shot it because the barrel looked really good still.

x2 well put wrangler

Those little 55's are a pain to start when seating, with their flat base. I load tons of moly coated 50's for my 22-250 and my .223. The only benifit I've seen is I can go longer between cleanings. I've put 1000 rounds through both of those rifles in a weekend without looseing accuracey. I'm running moly in my 257wby for the same reason. If your going to shoot moly start with a clean bore, sqweeky clean or you'll lay moly over copper and never see the benifits of useing moly.

Is moly coating something hand loaders can do themselves to non-moly coated bullets or does it required a more industrial process?

Some bullets can be bought already molyed. Moly is easy to apply yourself. All you need is a dedicated tumbler bowl and some powdered moly. You can order moly from Midway. Some folks like to add BB's but its not necessary. I dont have a dedicated tumbler bowl so I moly bullets in a 1/2 Qt jar. I just put the bullets and little moly powder in the jar. Put the jar in the tumbler and let it run for around a hour. I only do 100 .224's or 50 larger caliber bullets at a time.

Moly coated bullets are basically a gimmick. The idea behind them is sound (ish). Create a super slick coating that helps with velocity and cleaning. However, the "lube" is mostly gone in the first few inches of the rifling, if you add in the cost per bullet it gets pricey very quickly. What many are doing to save money and have much better performance is to moly lube the barrel. It will coat the complete interior of the barrel for less and will last longer. It is a process, not a drop in procedure, and may take a few hours or even days. I have personally seen rimfire barrels gain up to 300 fps, usually around 150. A friend has his muzzy treated and it was awesome, bumped velocity and cleaning was a breeze. It does not, or at least is not meant to, increase accuracy, but it can help.

One thing to note, not many competition bench shooters use it. Some may but I don't know that many. I think it would be great for varminters or people who put a lot of rounds downrange at a time and don't want to worry about heat or always cleaning.

I wanta add, the bullets or bullets and BB's peening against each other is what impregnates the molly into the copper jacket.

Mookie.
Have you used molyed bullets?
