I think the "err on the side of missing" argument falls apart when the shooter and target are approaching things from different perspectives. It might work for a shot or two, but if at some point the target keeps using the "you should feel like you missed me because I'm not calling hit" while the shooter is feeling more and more convinced that he has hit his target than it will lead to more zombie complaints.
I agree that there are going to be times when a person doesn't know they have been hit, and don't call it. At a recent public game at CIMAX I was firing at a target. We were both behind wooden barriers, but I had elevation and could see his head when he was taking cover. I would pop out, fire a few rounds, and pop back behind cover. After 2 or 3 exchanges, I popped out and continued firing at his exposed head. As I popped back in, the Field Marshal looked at me and told me I was out. He said, "You're out, he hit your gun."
I thanked him, called hit, and walked out. I had no idea the guy had hit my gun! I don't even know how he got the shot off. I was worried though that because the Marshal had to call it that they might label me the "gaijin zombie."
A few rounds later I swapped to my gas handgun, and was very mobile. I snuck close to a target and popped off a few rounds at someone who had no idea I was behind a barrier. He reacted to both hits, looked around to see where they came from, and then ran to join his advancing team members. It was pretty hard to give him the I-must-have-missed benefit of the doubt.
I think that most of us do accept that we might sometimes miss, but if it happens time and time again, people inevitably get frustrated. I don't play with high caps, and usually have a maximum of 4 or 5 mags with 30 - 60 rounds per mag. I usually don't play full auto, even during full auto games. If I have to unload a full magazine
(or more) just to get someone to call a hit, when they should have called it when I hit them 60 rounds ago, that gets frustrating.
I think, as others have said, we all need to be conscious of impact, sound, etc. I would rather take a "when indoubt, your out" approach because it takes the focus off the other players. Meaning, if I don't call it, cause maybe it was a ricochet or a branch, etc, then the other player has to forgive me. They have to internally agree that maybe they missed me. If I call everything, then they will hopefully never be in a place to doubt my integrity...
Played on Friday indoors. I fired 2 tracer rounds to my left as I was getting ready to relocated to my right. 1 shot bounced of a curtain, off the floor, off the wall, and hit my team mate...and he called HIT. Oops. My bad
Sorry for the ramble...feeling very unable to communicate today
