We also have a line of bullets that is doing very well here in the States with the IDPA/IPSC shooters. The hollow base bullets in .45 185 is an identical bullet to the 230gr profile but ways 185gr. It is my most accurate .45 bullet. We did the same in the .40 with a 180gr FP or RN making it weight 155gr. We have a 9mm 124 RN and FP that is the same profile as the 147gr.
