Round Setback


Often we will clear our semi-automatic firearms before it is stored, but have you thought about the top round in the magazine? Over time, a round that is chambered repeatedly can develop what is known as “setback”. What this means is that the round is pushed further into the case. This can spike the pressures when the round is fired, sometimes into the unsafe range.


The solution to this issue is simple. Just shoot your carry ammunition once or twice a year. Rotating your ammunition as soon as you see signs of setback is a good idea, but shooting your carry ammo means that if you have 2 or 3 rounds with some setback, you will not have to worry anymore. Of course, shooting your carry ammo will also provide you with recurring feedback on how the round feels and prints on the target.

Always be safe and remember the 4 gun safety rules!
