DISCLAIMER: NOT SCIENTIFIC, BUT DAMNED FUN!
Put 200 rounds through a Taurus PT-911. 150 of these being 115 FMC by PMC and 50 Federal 147 Hydrashok JHP. Targets were 2 litre soda bottles filled with water and wrapped in thick, oily rags and backed by 2 inch thick wood. I recovered several of the rounds from the tree which was behind the wood. The 147 JHP failed to expand due to clogging of the cavity in most cases. the times it did expand were dramatic. I feel a bit more comfy having the wife-to-be packing these in her gun, but I want to test 115 and 124 grainers too.
