mos2 is great
One of my old barrels 6x47 shows Very
Little fire cracking after 2200 rounds Just flat lands
easy clean and can handle a longer run of shots
I think a bloke named Keith likes it as well
I remember shooting the first 2x 60.10s at Bendigo Queens years ago with it after it had fired 900 rounds, I remember Alan Fraser watching =D>
Give it a Go you wont be sorry, Oh won the Queens

Moly is an easy button, but use it for the cleaning help before round count

I moly everything over 185 in 308.
I really don't see a down side. Increased barrel life, clean every 300 rounds with JB or iosso (which is necessary anyway) and easier to clean. No neck weld and auto neck lube because its on the bullet.
Mollying bullets accounts for far less time than just the time spent cleaning if you don't moly bullets.
The only thing I'd say is maybe don't store thd gun for months with moly in the barrel. Rumor has it that it might become acidic. Rumor also has it that it doesn't actually survive the firing process and what is actually lining the barrel isn't moly anymore.
Either way it seems to have the desired effects with no notable downside

G'day All,
I've been molying my bullets since the late 90's in Benchrest and F class for all of the above reasons and the only thing I believe is letting me down is wind reading.
1st shot from a clean barrel (butches boreshine and iosso) will be low but good for wind call then I can shoot 50rds before I clean again.
I dont bother for hunting rifles except for varmint rifles when shooting a lot
PS I dont anneal because of moly and cases last the life of a barrel (3500+)
Hope this helps
Cheerio Geoff

I moly projectiles and case necks

Downsides:
first shot from a clean barrel is low by about an moa
its a filthy job
moly doesn't coexist with Norma brass, at least the batch that I have see >> viewtopic.php?f=5&t=16287
barrel has to be oiled before storage due to the risk of moisture being trapped under the moly, causing pitting

Upsides:
ease of cleaning, for me this is the deal maker
consistency in neck seating force

G'day all,
in addition to my last post, I always clean before storage and push a damp patch of Hoppes benchrest through the barrel before storage.
Never had a problem with with my barrels.
FWIW of course.

I used WS2 before I retired from shooting, still have all the gear, simple process if done properly and it’s definitely not a filthy job doing it and WS2 also doesn’t come off the projectiles on your fingers when handled.
Just to see how well it adhered to the projectiles I actually tumbled some with my brass to see. Didn’t make any impression on the coating so could only assume it wasn’t fouling the barrel either. Only ever neck sized, cleaned barrel each week after club shoots, or if competition, at the end of the day which would be a maximum of 51 rounds if you needed both sighters and 15 counting shots. Using two glass jars, steel ball bearings and a tumbler with usual amount of media I could coat 300 .308 projectiles at a time.

I haven't coated bullets yet but have been considering trying HBN on ELDM tipped projectiles. How do plastic tip bullets handle the coating process in a vibratory tumbler?

I have “wet” moly coated hundreds of ELD-M bullets in a vibratory tumbler without losing ANY tips. I have had A-Max tips shed though. I have not shot unmollied bullets for 30 years.
