Winchester .40 cal PDX-1 165 grain. Any word on how it has been doing ? I have a chance to get a fair amount of it at a low price. I have seen on various sites that its bonding process is not as good as some of the other bonded bullets and that it doesn't expand as well as other bonded bullets also. Have you heard or seen anything similar ? Never sure what to believe on the internet. Do you have any barrier test data on this round ? [ autos,glass, walls etc... ] I would be using it out of a Glock 23 and if the internet is to be believed it should come out at around 1100 to 1120 fps depending who chronographed it. is that an acceptable velocity for it to work or should it be used out of a 4 1/2 barrel ? I know most civilian shooting occur with little barriers but I have almost and I do mean ALMOST had to shoot on 3 separate occasions around cars and 1 around a structure so barrier penetration has been moved up my list a bit. They list the energy at 476 and the Silvertip and Remington's plain 155 gr jhp right at 500 energy. Assuming all three numbers are correct is that a noticeable difference between them in actual shootings ? Is that the main part of the " Lightning Bolt " effect you hear about ? Sorry for so many questions at one time but I can't really seem to find the answers anywhere.
