The Firing Line Forums - View Single Post - Best .40 Factory Round for SD (165gr JHP vs 180gr JHP)

I have shot LOTS of 155, 165, 180gr loadings (and even sone 200gr doubletaps!) in both my CZ40B and Keltec Sub2K rifle. The I have settled on 165gr for the 40B and 155gr for the sub2k. The groups are a slight bit smaller and more consistent with both of those bullet weights...but in all honesty the difference is minimal vs the 180gr loadings.
