It's interesting hearing different views about marking guns.
I've never come across guys that mark a gun for the wrong reasons... Pat's "poaching hashers."
It's usually well-meaning rookies.
Johnoly you certainly don't fit either of these groups... but you've sure made your gun butt ugly!
I've never had a marked gun and I almost never shoot a short fish, but crap... I did it twice last Friday.
I had not pulled a trigger in a few months, and the first mistake was my initial 40' freedive on a wreck in about 12' of visibilty. 2 cobia made a quick pass tight together. Cobia rarely give you a second look and are rarely ever short, so I shot the lead fish in the head and it went out through the gill, not really hurting him. The boat came over and I had them measure and release him right away. He was about an inch shy of 33" and appeared to swim away fine, but I wasn't happy about it.
The second mistake was many freedives and 3 scuba dives later with just one hogfish each in the box at this point. In better visibility, about 25', there were many small gags around, and then finally a bigger one took off immediately and I hit him from about 20' out with a freeshaft. It was a very good shot that almost stoned him, but once in hand he looked borderline. When the shaft was pulled out he came to life, and if I could have measured him there and released him he might have joined the ranks of the lucky humpback groupers with PHD's. I released him from the boat later and it was too late... so I might put a single mark on my gun for the first time.
Thinking my eye was off that day, I only shot real good sized fish from there on. I was happy with my 2 gags that went about 8 to 10 lbs.
I'm still always learning.
