moly coated vs.xlc barnes

[equalizer]

I'm breaking in a brand new armalite ar10 .308. Manufacturer suggests breaking in the first 200 rounds with a moly coated bullet. I've loaded 100 hornady moly coated boattail hprounds. I'm half way there. I'm having trouble finding more 168gr.bt moly coated hornady. BUT I found these XLC Barnes bullets 180 gr. hollowpoint boattail. On the Barnes box it says "Barnes solid dry film coated x-bullets" The bullets are solid blue,except the bottom of the boattail. If someon can please inform me I would greatley appreciate it. I'm sending a few pics for reference. Thanks for any help.

The Barnes coating is not the same as moly. Moly coating is a simple process, involving a tumbler, a empty clean peanut butter jar(small one), a spoonfull of moly and an old towel. Buying nakid bullets and coating them yourself will save a little cash. There are moly kits available at Cabelas, Midway and Brownells and some better reloading supply stores.

Manufacturer suggests breaking in the first 200 rounds with a moly coated bullet.

I would really like to know the rationale behind that. I thought barrel break in involved frequent cleaning so bullets down the bore could smooth out barrel imperfections. It would seem to me that moly would defeat that purpose. I have also heard, that if metal isn't cleaned properly after moly use, it can etch metal. Having never used it (and I never plan to) I don't really know first hand.

I have used moly since way back and have not seen any of the alleged etching or the related corrosion in any of my firearms. I have seen increased accuracy and better all around performance.
Just my two cents. And each to his own.

Read something over on "thefiringline.com" about barrel break in.
Some barrel makers, void the warranty, if you used moly bullets.
Just what I read over there.
