I just recently got into hunting with a rifle. In antipation of my hunt, I spent lots of time at the range - first zeroing from the bench and then practicing with the bipod that I planned to used.
When I used the bipod my zero was different. I chalked it up to not sighting it in properly from the bench, but I just read an article today by Craig Boddington in which he said the bipod will change the zero.
My question is why? Shouldn't zero be the same regardless if the rifle is supported by sand bags or a bipod? Doesn't make sense to me, but I experienced and Boddington said it so it must be true - right? Wrong?
