I ordered some Corbon 115gr +P 9mm ammo and some Double Tap 124gr +P 9mm ammo. I was a little surprised by their differing overall lengths. I looked at my 180gr and 230gr 10mm ammo and they were pretty much the same overall length. I won't have a chance to shoot them for a little bit but I was wondering if this is normal. It's for my Kahr PM9.

| Case lengths look the same so they should function. I am curious though if the reliability of loading would be changed with the longer bullet. To me it looks as if they would be seated at the same depth but the one on the right added the extra weight of the bullet to the length beyond the brass. I just checked some 115 grain vs. 147 and there was a slight difference but not nearly as much as the two you posted. I also checked some .40 in 165 vs. 180 and they were the exact same. that was a 180JHP vs. a 165 FMJ as well. I figured the hollow point would have been much longer due to the redistribution of material to make 180 grains and the void being a hollow point. |
