I would seriously think about changing ranges, fast!
I use Speer Gold Dots. Usually +P in 9mm and 45acp. Fast and hot. There are other equivilant loads out there, the most important thing being is it reliable in your gun? And the only way to find out is to shoot the stuff!
So. I shoot at least a couple of boxes of Gold Dots in my carry guns every trip to the range, regardless of cost. No reloading here. I want it factory sealed to perfection. THEY have a reputation to maintain. I don't Nor does my reloader. I want one hundred percent reliability. Not 99 ... one hundred. That means no misfeeds, no duds, no nothing except bang when I pull the trigger. Bang. Every time. One hundred percent.
You are betting your life on the load. And you have got to know. No exceptions. Jeez. They gotta make an exception at least for testing self defense loads, no?
Like I say, I generally keep about two or three hundred rounds in stock of each of 9mm and 45 acp. Gold Dots. And I stamp the date on each box. I rotate through them monthly.... never more that a half year or so old. My life is worth it.
One other thing. NEVER keep the magazines fully loaded. I always rotate through the magazines also and keep several spare springs on hand. I rotate the magazine and the springs. And I never keep a magazine fully loaded to compress the spring for long periods of time. I usually take the loaded magazines to the range and fire them off every couple of weeks and then rotate to some new ones. As soon as I feel the spring is getting the least bit mushy I replace it. And I keep the mags clean as a whistle all the time as well and occasionally run a fluffy brush through them with some dry lube on it. Never we lube. You don't want to be killin the primers or the powder or attracting dirt.
Be safe out there.
