IMHO, if you just shoot the inexpensive domestic ammo like Winchester white box or Federal red box, you pay a little more bit have reloadable cases left over that you may find a use for in the future.
Co-worker has some issues with his flat top firing Bear .223, he would run a 30 rounds and then the jamming / misfiring starts - might be from the laquer/polymer coating (not sure). He has had enough, I advised him to use the remaining rounds 30 only per visit to the range and fire winchester, pmc, etc.
I wish I could provide other details - on the malfunctions with the bear! I have had numerous attempts to get hime to the range; however, honey do list comes into play!
Wednesday, is a coming and it is range time; however, the winds will calm down! If the winds are going, time for drive to the Gun Show this weekend 1-2 May at the Expo Hall in Albuquerque!
