Ok, so I'm coming from an Ion which I didn't take care of at all, so you'll need to help with some of this stuff.
1. How do I take apart the HPR and LPR?
2. When I 'clean and regrease' what grease/lube should I use and what should I check for in terms of the springs and pistons?
3. I put about 3-4 cases through it and it sounds like a shotgun and has some kick to it. I tell myself that it's just that I'm standing behind it but after hearing others' quests I've changed my mind. LPR is at about 100.
