to Moly or not to Moly that is the question???????

[20series]

OK this will possibly open up a debate.................

With thought to my .284 in a few weeks I'm considering using moly coated bullets, now I've done a little reading and the general concensus is that you'll gain barrel life (a bit!) but lose velocity (a bit!)

now can any of the more experienced load meisters shed any light on the pros and cons as to likely outlay of kit and likely benefits or not?? :roll: :roll:

I wouldnt ive been down that road and unless you buy already loyed bullets its messy and a real pain in the arse to do , yes you get less fps and yes barrels are meant to last longer but the on flip side cleaning is a real nightmare as its got to be stupidly clean after use. you will need more powder to obtain the velocities nodes in which some of the vld type bullets like to be in.

My take on it...

We Moly coat in this house, mostly on Christels rifle so we can shoot full cases and stay range legal at sub 1000m/second. Finding her bullets moly coated is a nightmare so we do it ourselves using a Lyman kit which is a couple of smaller drums that fit on the Lyman Turbo Pro 1200. Moly coating is incredibly simple and we get perfect results, drop 125 bullets into the first drum with a quarter of a flat teaspoon full of Moly (comes with the kit) the drum is filled with ceramic media, run the drum for 180 minutes, I use a timer for ease and accuracy of coating, empty the bullets out and tumble them in the second drum which has corn cob media in it, this is done for 5 minutes. Empty out the bullets and pop them in a bag ready to use. Job done.

She has a tad over 900 rounds through her barrel now, accuracy is still outstanding and everything is running very smoothly right now.

Cleaning wise I am not prepared to discuss the cleaning regime she uses in a public forum, suffice to say she does it her way and it works rather nicely if the 30mm 5 shot group she shot at 656 yards in September is anything to go by. She also shot well last time at Stickledown.

Once accuracy drifts off I clean the barrel for her, this is usually around 125-130 rounds and once done she shoots 4-5 moly coated foulers and puts it away for next time.

I use moly in my AI with 155 Scenars.

Afternoon gents,

My fclass setup came with load data based on using moly and I've kept it up, self coating is pretty straight forward, though as Spud says can get a bit messy, ( not a job to be done in the house). Cleaning , to me seems about the same, barrel life - don't think you'll ever really know unless you take two identical barrels and shoot them in an identical fashion only difference being moly/non moly.
Like yourself had a good google and read up and there are those for and against, plus many more who believe it makes no real difference.
I recently bought a 6mm that came with 1000 moly'd DTACS, so I'm going to shoot everything with moly with the opinion that the only real downside is you need a little extra powder and a spare day to coat a years worth of bullets for 7mm and 308.
I'll think about it again when my 7mm is shot out. In terms of actual shots on the target it cannot make any real difference or else everyone would use it. Probably just another part of reloading you can either do or not do, falling into the realm of how far do you go to produce ammunition you have complete confidence in.

All the best and an excellent new year to all , phil

Moly coating was covered a bit in this thread

http://www.full-bore.co.uk/viewtopic.ph ... ly+coating

This is the finished item for me, I prefer to tumble them through corncob at the end to remove any loose powder, this makes them a lot cleaner to handle and load with, in fact I can load a couple of hundred and still have clean fingers which is a bonus!

Moly coating your bullets will not extend barrel life - God, I wish it would!

Moly coating your bullets will reduce pressure and therefore muzzle velocity - most 308 shooters I know want as much m/v as they can get! I don't know any of the top shooters using moly bullets.

Cleaning - if you couldn't clean, and had to shoot say 100 rounds before you could clean your barrel, then I would concede that your rifle could be shooting better for the last 50 or so rounds than with un-coated bullets.

Moly is useful if you are using a cartridge like for example the 6.5-284 where you don't fill the case. Use moly bullets and you will get another two or three grains in the case - which can sometimes help accuracy.

But, this reloading thing is complex enough without introducing an un-necessary variable.

Don't use moly bullets unless you need to.
