Most of the component suppliers have been out of the bulk boxes (500 bullets) of the Sierra 9390 80 grain Matchking .224 which is the supreme bullet used for AR-15/M-16 Service rifle and Match rifle long range (600 yard) competitive shooting. I managed to snag a few boxes and they are for sale at $110 per box, plus shipping. Local pickup in South Denver/Parker Colorado. If you let me break down the Sierra box (break the seal) I can fit in a USPS Small flat rate priority and ship insured for $7.50. If you order more than one box, I can fit up to 8 boxes in a USPS Medium and keep the boxes sealed. Medium flat rate priority box and insurance is $15.70. These are factory new, first run production. Must use a 1:7 or 1:8 twist barrel. These are also posted on www.gunbroker.com is you want references, and prefer to buy through that site.
