I recently bought a FN Belgium custom Mauser in .264 WM. at a great price. My question is would moly coating my .284 bullets help in any way with barrel longevity and or performance. I was kicking the idea around because I have a 7mm Rem Mag that I presently load for an thought the moly coating on the .264 would help me at a glance to keep the two rounds separate so as to prevent an accidental loading of a .264 into a 7mm chamber.

I've played with moly on hunting bullets. Biggest issue I had was removing it after I decided it didn't help.

I think the 264 got a lot of bad press about barrel wear. If you don't over heat it I doubt a normal shooter would ever wear it out. The 7STW, 7RUM, 6.5STW, 257STW will all be harder on the barrel than the 264.

The 7mm shouldn't chamber in the 264 and firing a 264 in a 7mm will only resize the case and give you a real bad group.

If you want to try go for it. For my time and money I wouldn't fool with it. Moly was the thing for awhile and the newness has warn off.

Ramrod beat me to it. Ditto on everything he says.

I peen the Moly into the Bullets and then coat them with Carnuba for 99% of my rifle bullets. It can be a bit of a mess doing it yourself - at first - but once you get the hang of it, it is no big issue.

I began using Moly a long time ago just because of extended barrel life. I have one particular rifle that likes nearly anything I put in it and do not look forward to the day that the barrel would need to be replaced. So, I began Moly Coating Bullets for it. It worked so well that I'm now using it in all my rifles, except for one new one that I'm using a lot of Lead in. May begin using Moly in it too though.

Yes, the Moly Coating would distinguish them very easily from the 7mm cartridges.

A couple of nice side benefits to the Moly Coated Bullets is you increase your BC by 4%-6% and barrel cleaning is very easy. You still need to clean the Bore after shooting it and apply a light coat of Moly Grease in the Bore to finish. Then wipe with a couple of dry patches to make sure there is no excess Lube.

I like it and will continue to use it until something better comes along.

Best of luck to you.

This is my primary objective. I probably would not bother if there was no saftey issue involved, but then again this overbore cartridge may benifit somewhat from a moly treatment.....I think the scales tipped in favor of....Thanks guys

What safety issue?

You can shoot .264 ammunition in a 7mm Remington chamber until the "cows come home" and will never have a "safety" issue (unless it is for some poor unfortunate downrange who gets in the way of an errant bullet).

You can't even begin to chamber a 7mm Remington cartridge in a .264 chamber. So, like Ramrod, I have to ask, what safety issue?

If you want to readily distinguish one from another by sight, it would be much more effective to use nickeled brass for the 7mm and regular brass for the .264.

I have identical guns in .222, .223, and .222 Magnum. I have no trouble in keeping straight which ammunition goes in which gun -- even when some of the .222 is made with reformed .223 brass!

Duly noted, however I am a little gun shy in the mis-chambering department as of a few seasons back I had purchased an off the shelf factory box of 7mm rem mag cartridges. After 2 or 3 uneventful rounds downrange I chambered in the next round only to have my stock grenade between my hands and other debris going every-which-way. I thankfully was not seriously hurt and the Ruger action held together, but somewhere along the line 3 .270 win. rounds wound up in that box. Yes I should of checked but I did'nt. Until it happens to you I think one will understand my over cautiousness. Any way the nickle brass is a very good option and I will now take that action....Thanksagain

I agree that Nickel Cases will work, but they have their own problems - flaking and tough on Dies.

You could simply use a Marks-A-Lot to color the Bullets for the 264WinMag after you have them Seated.

Glad to hear the Ka-Boom didn't permanently damage you.

Don't know what kind of case you keep your ammuntion in but if the rounds are carried primer up just put a little sealer on the primers. I comes in a fingernail polish bottle and is usually blue or red. The marker idea should work fine as well.

i wouldn't go nickel cased at all good reason stated above. i think moly works is it for everyone? probably not. how many people can argee on ever thing, test it your self, and please use two different ammo containers for your different calibers. couple of years back a friend had his 270 wcf. ammo and 308 winchester in the same plastic box, yeah you guessed rite he chambered his 308 shell in his 270 styer rifle,it was a loud boom and i had to beat his bolt open with my rear leather sand bag! the gun held nothing blue apart,i pulled the bolt looked for cracks on the lugs every thing looked fine ... sooooo i chambered a 270 wcf. round and fired it down range my friend called the shop where here bought it and they said go hunting they test em with more pressure than what happened with us by mistake at the factory.wowser i said when i heard that one!!! two guys were siteing in at 200yds next 2 us getting ready for an up comming quebec caribue hunt, when they saw me beat that styers bolt open they left in a cloud of dust,i gigled and said out load ''what don''t they trust us''? i keept that 308 case just 4 reminders .
play safe

If you want to try Moly then go for it. I found it to be a royal pain in the a$$. I have removed it from all the bullets I put it on as well as factory applied.

There are far easier ways to keep your bullets straight. I simply use different color boxes. I have also painted the heads (ususlly to tell different bullet types in the same cases). As we have said there is no danger in a 264 fired in a 7mag and a 7mag can't chamber in a 264.

I'm also no great lover of nickel cases for rifles. To me Moly to keep them apart sure seems like a hard messy approach to what could be a very simple issue.
