Stop using fmj's and shitty heads. Get some heavy 2 blade single bevel heads made out of real steel, make them razors and then cut the pigs spines in half. They go nowhere. Resharpen, repeat. I was blown away at the difference in penetration and damage when I made the switch. Just got back from bama and every hog or deer I stuck died in sight. Four deer, two hogs. On one (84 lbs) the spine was completely cut in half, got one lung and then blew out a rib on the way out. Arrow didn't fully exit because there wasn't room but it was stuck in the dirt too. Happy to come show you
Ive only had the DPP on my pistol for a couple weeks and haven't shot it enough to really give an educated opinion on durability yet. It has held zero for the couple hundred rounds I have through it and the nice clear window is ample sized for dot recognition, even with a quick fairly shitty presentation. My main bitch so far would have to be the single button for dot adjustment. Cycling through kinda sucks. I have heard they eat batteries, but haven't had it long enough to know how bad.
