Trimming 223 for 300 blk - YouTube
This seems to be the quickest method ive seen just using a cheap little cut off saw and some wood. After that you would just have to trim a bit which is where im stuck at. I was able to get a hold of Lee and they said that the 300blk case length gauge is considered a custom caliber that they have to shut down normal operations to be able to make so they wont be making anymore for about 6 months.
I did find these guys though All Weather Arms
and for $55 they will convert 1K rounds of 5.56 to 300blk for you or for $110 you can buy 1K rounds of 5.56 already converted over to 300blk. Figured id go this route and by the time I burn through 1K rounds of brass Midway should be back in stock.. Hopefully....
So how does it feel to know that someones kid in the heart of America
Has blood on their hands, fighting to defend your rights
So you can maintain the lifestyle that insults this family's existence
Well, where I'm from we have a special salute we wave high in the air
Towards all those pompous a$$es who spend their days pointing fingers
F*** you!!! -A7X
