popping primers tying up an autoloader, and THAT can be prevented. It's no big deal to crimp or stake in or otherwise secure a primer in its case , ya know. It takes a LOT more pressure to cause any serious deformation or splitting of a 223 case than it takes to get the sort of velocities I claim, for 10-11" barrels, <font color=red>*</font><font color=red>*</font><font color=red>*</font><font color=red>*</font><font color=red>*</font><font color=red>*</font><font color=red>*</font>. Nobody said you have to PRACTICE with such loads, ya know. Or even with THAT upper, or THAT AR. u dont need to fire 1000 rds of 223 a year to stay SHARP (either shoulder) if you use a silencer and practice with the 22 unit (5-10k rds a year) so it's your stupid ASSUMPTIONS about how many rds are to be fired, (hot loads) that make the whole thing seem out of line.

Yeah, you don't ever have to practice with the .223. . . .unless you want to be able to hit outside of pistol range, as the .22LR and .223 are nothing alike, ballistically. But you've as much as admitted you can't shoot a rifle past pistol range, so. . .

You've never tried loading them that hot and firing multiple rounds of it on a regular basis out of a CAR-15. If you had, your wouldn't be talking the same BS tune.

You practice with what you fight with.
