Hornady seems to have whipped the "clogged with clothing" reason that hollow points do not open correctly sometimes. Their polymer in the cavity helps push open the petals of the HP even if it is being pushed by clothing so when it does enter the body it is open or opens very rapidly. So it seems they may have nipped this issue in the bud with these new rounds.
Now, would normal silicone in the cavity of our HP's make them act more like they are supposed to and not clog either? I do not have ballistic gelatin so it would be hard for me to tell if it works or not. But maybe a squirt of silicone in our HP cavities would make the rounds we already have work better and not clog as easy with clothing and expand better?
The post in Hydra-Shok's helps even the opening of that HP unless of course it gets half plugged with clothing as it is likely to do. Same for the great Ranger SXT (Black Talon) rounds, great HP with it's heavy petal tips but it can clog and not open correctly too.
The silicone would add very little weight to the round but may just help it perform as it is supposed to, after going through clothing. What do you guys think?
