Triton Hi-Master 9mm 135 grain at 980 fps. Real tight standard deviations and extreme spreads. Also real accurate and mild to shoot. Dave Sevigny won many a match and spanked many a shooter with that load.
I know... I know, you can't find that ammo anywhere. Spent so much time working on that load I just had to mention it.
Evan Marshalls' research indicated even the bargain brand of WalMart sol Winchester white box and Remigton bulk pack 115gr JHP do very well against the top name brands. I use the Rem 115gr stuff right now - it allows a lot of practice on a budget while still giving decent performance as an SD JHP, from what I have been told.
First of all,why limit yourself to non +P? Any quality weapon can handle at least a limited diet of the +P stuff,and it really takes the 9mm to a different level. If I had to limit myself it would be to plain ole Federal 9BP 115gr JHP. TJR
First off, I reload all my defense ammo except Starfire, because you can't buy the SF bullets seperatly, and all my loads average 1150 fps. I shoot an older HP, and don't want to stress it anymore than I have to. My reloads cost about five bucks a box, the WalMart bulk Win. fmj cost twelve bucks a hundred, and I only buy these for the brass. I'll go for decent shot placement over 50-100 fps every time.
124gr Speer gold dot all the way. I have done my own ballistic testing,with dry wall plywood, water jugs stuffed with water and toilet paper to thicken it up, even used hardwood dowells to simualate ribs, and put a sweat shirt over the whole thing. And tried and true the gold dot always expanded the way it should with no core jacket seperation. The 115gr would expand but the penitration was not all that good. But another side note what ever ammo you use, it will all do the job. Once a person knows they have been shot, trust me the situation is over from there.....
I have read extensively on this very subject. I have come to the conclusion(s) that...
1) for standard velocity (non +P) 9mm ammunition, I will use Winchester Ranger "T" series 147 grain JHPs - RA9T
2) when high velocity 9mm ammunition is desired, I will use Winchester Ranger "T" series 127 grain +P+ JHPs - RA9TA.
