I went to a range yesterday and took a box each of CCI Blazer TMJ 180 gr. and Speer Lawman TMJ 155 gr., both in .40 S&W. I basically wanted to test how my gun behaved with both of these rounds trying to pick up the best in accuracy and everything else. At the range, I also got a box of FMJ 180 gr. factory reloads for a "third party" comparison.
The accuracy of all the ammo was roughly the same -- I'll probably have to shoot much more rounds just to see any difference. What I felt, however, was significantly stronger and sharper recoil with Speers 155 gr. as compared to both "reloads" and Blazer which recoiled exactly the same. Each shot with Speers, moreover, was noticably louder as well. Does anyone know a good source of info on why it is like that, what factors change based on a bullet's weight such as speed, recoil, etc? A web link would be just great, but any personal info or experiences are welcome too. Thanks.
