Cor-Bon/Robinson 6x45 caliber

[tpd223]

I don't recall which writer it was, but one of the hunting magazine guys used to used this round out of single shot pistols. I thought if it worked on mule deer at 200 yards from a 14" Contender then it should make a really decent carbine round.

I knew a guy who had an AR upper in this caliber, like ten years ago, he had to handload for it.

From the Robinson site:
"We're working on this caliber which is not new but is nevertheless very interesting. The idea behind this caliber is that one modify 5.56 brass and find projectiles from 70 grain to 107 grain. 6mm projectiles have great cross sectional density. The other neat thing about this caliber is that one can use 5.56 bolts and magazines. Corbon will be offering this ammunition."
