With those results the best advise I can give is....buy and shoot Wite box fro Wally World.
Where did you get that load recipe...?I've had a pretty bad experience reloading 40 S&W. Winchester 231 5.8 grains 155 fmj in a stock barrel will come apart at the base. The same load with a Lone Wolf barrel was catistrophic. Changed the load to 5.3 grains an second round came apart. All brass is range brass. and all rounds chamber checked. View attachment 6
If you know the correct formula that would be good.
All gun manufacturers advise not to shoot reloads in their guns. Because Glock doesn't have standard rifling, lead bullets should not be used. I've always had good luck with plated, cheap and clean! When I'm developing a load I usually check a couple sources and remember to start on the low side and work up to max if you ever need to. Tip: flat primers = too much pressure.Hey thanks Gray Wolf, for your input.....I do appreciate what you've said. I am SO glad that I can reload my Glock. Since in all of the owners manuals, they strongly say one can't reload. Sure, I know that is in case of a problem, and the gun goes BOOM, they won't stand behind their warranty. However, Since I am a cautious person, and somewhat meticulous, I don't expect any problems. (and as you said, Knock On Wood)!
I guess My plans right now are to purchase the Lyman Manual, before I start to buy the rest of my equipment.
Oh yeah, where did you get your formula for your reloads?...Thanks again..
