For whatever reason, I’ve only shot 180 grain in this caliber. I guess because the first time I bought some ammo, 180 was available or cheaper or recommended. I really don’t remember. Local gun store had some 165 in stock so I bought a couple of boxes of Blazer Brass. They had a few more boxes of WWB in 165 as well. So, I bought the Blazer on a whim just to see if it’s any different from the 180 grain. Most of what I’ve shot is Magtech 180 and S&B 180 FMJ target rounds. And WWB 180 grain JHP’s. I’m guessing with the Blazer 165, I really won’t see any noticeable difference. Shooting a Glock 22 and a Beretta PX4 Storm. Anyone think there is a big difference between 165 and 180 for .40?
