Just wondering what you guys think about molycoated bullets. Does the moly add speed or reduce it. I've used them in my 22-250 but have never cronyed them. Love to hear what you think about them.
 
Ive only used them in 3 rifles. My Husqvarna 7mm absolutely loves the Nosler Combined Technology bullet (maybe not moly, but some coating). My wifes Weatherby .30-06 hated moly bullets of any type and my Remington 700 .308 shoots Speer 168gr moly bullets very well. The velocity doesnt decrease, but I honestly havent noticed any real discernable increase either. I clean my rifles after every shooting session so I havent noticed any real 'gummed' up rifling from using them. I love em in my 7 mag, take it or leave it in the .308 and avoid like the plague in wifey's -06.
 
I forgot to mention my cousin tried the Winchester Combined Technologies bullet in his Remington XCR .300 with 180gr bullets. They grouped well, but drastically higher point of impact than any other 180gr bullet. Roughly 2.5 inches higher at 100 yards. Unfortunately I didnt have the chrony out that day to see what was going on, so still not much help for ya! Ha
 
If you use the same powder charge as a un-coated bullet, the velocity is lower with moly. I find that a 308 needs an extra 0.5 gr to keep velocity the same.


Moly reduces fouling and makes cleaning easier.
 
I've used moly since 2000 or so, I use it because I'm lazy. I like the fact that it takes alot longer for fouling to affect accuracy which means I do less cleaning.

Moly is not a magic wonder powder, no increase in accuracy or anything and for sure you lose velocity. With moly I have to bump my powder charge by .4 - .7 of a grain to get back to where I was.

I'm going to be loading cast in a gas-operated gun, and rather than swapping out lubes in my lube-sizer to accommodate this (I also shoot BPCR, so a bit of a PITA, and I don't think I can find 1 lube for both extremes), I was thinking of using either liquid alox or moly for this application.
 
I will second what Ganderite said. However to dtkb, once the bore is coated with moly there is no reason to clean until the groups open up, unless you get caught in the rain. Some barrels can take up to 20 rounds or more to "settle in" when going from a clean barrel to moly.
 
I'm using moly for the easier/less frequent cleaning.

-Mark-II, I'm assuming that you're following the thread over at Cast-Boolits? I wouldn't use straight LLA, it's a little too "gooey" I wouldn't hesitate to use the "45-45-10" formula tho'
