Ammoman has Lake City M855 on Stripperclips in cans.

Sportsmans Guide has Winchester M855 on Stripper lips in 900 rd boxes.  Price is close enough to not be an issue.

Are both factory seconds?  I am interested in which is most consistant.  Planning on adding to my stash of IMI M855.  

Please don't tell me to get XM193 or Q3131.  ( I have 9,000 rounds of Q3131A).  I am talking just about M855 ammunition that I wish to set asside.

Thanks,

Well, you can check the industry forum for Ammoman's feedback, or go to the EE and look it up under feedback.  Either way, you might just want to go with Sportsman's guide....

The thread in Industry is gone, but here is a link to the feedback thread...
