Moly or Uncoated Bullets?
which is better? What is your experience? Is it good to use moly coated bullets on breaking in a barrel?Does Moly give better velocities? Is Moly harder to clean out of barrel?Thanks

Have you searched this using the search engine? I would imagine there is a whole lot of info from the past. I am replying to you though since I occasionally post on snipersparadise.com and they have some great posts and comments on moly vs non. You will find that the majority say non-moly. Also, longrangehunting.com had some great threads here recently on it so check there also since there are some strong believers in moly there.

I dont have the exact reference, but a couple of years ago Rick Jamison did a very nice study using moly and non-moly bullets. It was published in Shootingtimes as I recall, and many shots were fired, so the data was statistically significant.

One thing I do remember was that moly gave lower pressures and velocities, presumably due to lower friction. Barrel life etc, was addressed but I do not recall the conclusions. I usually do not put too much weight on the data in gun-rags, but this was probably one of his better write-ups.

What are you doing? Shooting competition where you may fire 80 or more rounds in a day without cleaning? Shooting prairie dogs where you may shoot hundreds of rounds a day? Or just shooting 10 cartridges a year to sight in and kill a deer?
If the former, moly is great, if the latter, it isn't worth the effort.

Do you handload? Or do you plan on buying ammo off the shelf or shooting lots of surplus ammo. Again, the former, it's great, the latter, forget it.

It doesn't matter. The barrel will break in fine no matter which you use.

Slightly better, yes. But you may have to experiment with powders. You have to use more powder. Moly lowers pressures and velocities for the same charge weight, but lowers pressure more. So you add more powder and you can get higher velocities. But, it will cost you.

No. After a hundred rounds or so, or after an outing, 2 patches with Kroil and one dry are all you need to clean with. After 300 or so rounds, 2 patches of Kroil followed by 2 patches of JB Compound and a couple dry patches are all you need. No soaking or wire brushing is needed.
