How do you guys go about zeroing/target practice with a moderated full bore rifle? I've always zeroed by rattling off three shots in succession, checking the group and adjusting accordingly before firing another three. Well I did that last weekend and couldn't get a tight group, each succesive shot was higher than the last.
I've read that the temperature of the barrel and mod can make a noticeable difference to zero, and my 270 gets incredibly hot after three shots. So I've been thinking that the next time I go to the range i'll fire one round, put it to one side for a few minutes to cool down, rattle off a few mags on the .22 to keep me occupied, and then squeeze another one off the .270. Does that seem sensible, or is there something better I could try? Seems to me that the zero with a cold barrel is the most important as it'll most likely be cold when fired in the field.
