Using Molly Bullets

[fourxfour44]

Hi All, I recently bought a .223 Browning A Bolt, I loaded up some 50grn V Max with 25grns V/V N133 and it shoots very well - no problems at all - 1/2" groups all day at 100 yards.
My question is :- I have some 40grn VMax bullets which I am intending loading, but I have heard that the molly can foul the barrel causing poor groups etc.
I only have 100 bullets heads, once used I will probably go back to the original 50 grain load.
So do you think I can clear out the molly then go back to the 50 grainers without loss of accuracy, or should I leave them well alone ?.

I shoot moly in all our target rifles.
Only thing it will effect is the first few shots when you change or just clean it good before you go back to bear bulets. I've shot moly for several years and ain't had the buildup problems that some said they have had.

Once you go moly you may never go back. Less copper. It won't hurt anything to try it what so ever. Mike

+1 for kermit.

I also shoot molly in all my target rifles and have for 15 years. Never had a problem and molly makes it a lot easier to clean the barrel.

I tried molly in a 17 Rem. and it fouled so bad that I had to fire lap it to get the Molly out. I did not try that untill I had given up on everything else and was ready to rebarrel it. I will never shoot Molly again.

Interesting......as moly cannot build up on itself......

When you shoot moly for the first time it is important to start with a clean barrel or you are moly coating copper and carbon that is in the bore. This will make it hard for the cleaning agents to get to the dirt below the Moly and create layers. Fred Sinclair wrote about this in his 10th edition of reloading. Mike

Thanks for your replies, I think I will give them a try - and be prepared to give the barrel a good scrubbing!

Also, make life easier for after shooting the molycoated bullets and get a dedicated moly remover such as boretech and plenty of others make. Lots of "moly attracts humidity and moisture=rust" stories out there, although personally I think Immike may have it right with people just coating up already foul barrels. Either way, I wouldn't chance it and get scrubbin'.

Agreed.

Not moly... sounds like carbon to me...

If you over apply the molly so it is almost caked on the bullet then you might have problems.I coat them and then polish in fresh cornmeal so they look like chrome sort of and have never had build up one time and it cleans up easy.

Switch to wet apply and you don't have any dust at all...
