I've always been of the belief that using a 308 can on a 223 is more than good enough and certainly more practical. I now have a 7.5" 223 upper that's going to dish out more abuse than my 308 can will take. I had my mind made up and was going to call my dealer this week to get a 556 Saker and yesterday, I see they are going to offer the "same can" in 762.
Other than the smaller physical dimensions, is there any true benefit of an actual 556 can over a "do it all" 762 can? I've used my 7.62 SD on my 20" AR's, 26" 220 swift and various other 6 and 6.5 mm's with good success.
I'm looking for members that actually own 556 cans and have also ran a 762 muffler on the same platform. I hate to dish out $1000 and be limited to .224 bullet diameters however, if it is truly better for the application, then I'll suck it up and do it.
