I got better accuracy with moly bullets

I was using 65gr. and 75gr. bullets in vmax in .243 and I got great groups with bullets I moly coated my self. But because of all the bad press moly bullets were getting and what I was experiencing myself, I went to naked bullets but they don't shoot as good now. I can go back to moly bullets but its likely that I will have to use JB Bore compound when I clean it and I don't like using abrasive cleaners in my rifles. I have one .243 that has a new barrel on it that shoots sub 1/4 inch at 100 yd with flat base bullets but the vmax bullet are not grouping as well without the moly. I have used up a box or 100 bullets trying to get these vmax's to shoot. Any suggestions?

To moly or not to moly; Molys drawback is it reaction to moisture, it creats a acid mixture that can eat at the bore of a barrel. Proper cleaning and lubing the bore with a patch of oil after usage can prevent this from occuring. When cleaning a moly barrel the secret is not to clean all the moly out of the bore. This coating is what keeps copper from building up in the lands. The only place that might need a scub is the throat area, where a carbon ring may form. It may take a dozen rounds to lay down a fresh coating of moly. Some people are switching to the new coating that are avaliable such as hbn and ws2 or whatever the new stuff is called. I'll be switching as soon as I run out of moly. RANDY

Coated bullets shouldn't be much of a factor for accuracy. You can probably get back to where you want to be by reducing your powder a little at a time.
There is no need to use JB to clean down to bare metal. Matter of fact, you're defeating the purpose if you do that. I no longer use moly, but using WS2 (Danzac), I use Patch Out & Accelerator followed by a patch of Lock Ease. This works well in everything I shoot.

Moly & better accuracy

Yep, I've had the same experience with several 22-250s. I've also had the opposite experience with a 17 Remington. Have you tried waxing your moly bullets? The people at Norma think that a wax coating also improves accuracy.
 
Bad Press?

I have 3,500 rounds of self-coated moly bullets (no wax) down my 7BR and it still shoots great! (Benchrest with 130's and Varget with 168's)

I clean the barrel every 50 rounds with Butches and a bronze brush.

Somehow, some folks believe moly is a reason for not cleaning. I guess they don't know about carbon build up.

About half the benchrest serious competitors use moly and the rest use naked bullets. They each appear in the winners circle the same amount of times. And all discard their barrels (6ppc; 2000-3500 rounds, 30 cal; 5000+ rounds) long before any abrasive cleaner plays any part in barrel wear. The moly "accuracy/barrel wear" arguments go on and on without either party convincing the other that what they're doing is wrong. It's a never ending cannot be won argument.

In my case, moly was a messy procedure that offered me no advantage in either accuracy or barrel life. Sooo....I went back to paying attention to my flags and the conditions which paid off a lot better that any bullet treatment.

You don't have to use JB paste every time you clean . It is just handy if some buildup occurs near the lands to make sure you get the excess moly and powder fouling also in that area. However that usually takes many shots to happen .
When I say buildup I don't mean Hoover Dam . Many people are over reacting to information they read. Moly does build up to a very small degree . Thats why it works. After firing hundreds of shots without cleaning you may see what I mean.
Another thing is that Mos2 has the " POTENTIAL " ( read potential not absolute) to react with moisture in the bore.
The combustion products can under very precise circumstances react with moisture to creat corrosive elements. However that is only a "potential " problem if you never clean or lubricate your bore .
Never cleaning or lubricating would ruin any bore mollied or not.
Some people got caught thinking that moly protected the bore from corrosion.
It don't. Even SS barrels are not imune to corrosion and some people thought they could just leave the molyied barrel dry and uncleaned permanently . Not a good idea.

The big problem is that many factory coatings claim the name "Moly" and many are not as good as the pure MOs2 coating you can put on yourself.
If you do put the coating on yourself at least you know exactly what coating you have!
However everyone lumps in all their experiences together with a dozen different factory coatings and home coatings all thrown into the pot.
Confusion is the result. The reatailers love it , because where you have confusion you leave a huge forum for the sales pitch.

True . The argument can never be won because there is numerous arguments going on under the one umbrella of Moly all at odds with eachother .
Wind is by far a greater factor in getting tight groups than moly will ever be.

If you did not watch your flags when using Moly of course you shot worse. Moly has no effect on how far wind pushes your bullet.
