. . . Mix and match .223/5.56 converted to .300 BLK . . Best group Around 5in. @ 100 yards. Will reaffirm these results this weeken and update. I believe one of our Mods noticed poor accuracy with converted brass UNTIL he anealed the cases & then re-sized. Your bullets & rifle suggest you should be getting a smaller group than 5" at 100 yards. |

If you're getting 5 inches at 100 yards yer doin it wrong. I know it's only 3 shots, but this is with 17.4gr H110 and 147gr M80 pulls. http://i19.photobucket.com/albums/b180/Jailer/posting%20pics/174grH110300blk.jpg I got the same results with same load out of a AAC 16 inch upper.

Quoted: Ive yet to look into annealing. Ill have to do that. Any links on the process would be greatly appreciated. Could a mod please move this to the official 300BlK thread? Thanks. What you need to do is copy your first post and paste it in a new post in the 300 blk thread. If I do it, it will look like I wrote the post because my avatar will be displayed at the post. (I have no special mod powers to move a thread into other threads)
