Someone have never proof heavy match bullets like 80 Sierra , 90JLK or other in 22PPC? How them work? are them accurate? muzzle speed?
thanx

Newest Rifleshooter magazine has a pretty good article about guys that have their AR15's modified to 22PPC to shoot heavy for caliber bullets. More speed than a .223 and they can be loaded in standard mag for a longer OAL.

that didn't come out right...........they can be loaded out of the case farther and still fit the magazine as the case is shorter and fatter.
