hi mate,
why don't you just boresight looking through the barrel at a small red dot or similar at 15-25 yds and move the reticle point 'to it'. usually gets me within 4" or so from 100yds. Then after the first shot, move the reticle 'to' the shot hole and your second should be zeroed, third to confirm and off you go
I KNOW, I KNOW. LOLI did tell you so Kev!
I KNOW, I KNOW. LOL
. JUST SINCE MAILING YOU I HAVE BROKE THE SCOPE ON THE 6.5 YESTERDAY .I HAVE A SPARE NOW ON ITI HAVE ALL READY GOT A RED DOT ON MY FENCE
.
That's exactly the way to do it, start with a solid position. (Bipod and sandbags or similar)
Boresight - adjust reticle to match - BANG - Wizz, Wizz reticle to shot hole - Bang to confirm. Job done.
If you understand the basic principle it dosn't matter if your scope is calibrated with 1/8, 1/4 or mm clicks, I've seen countless rounds wasted, by even very experienced shooters, walking their shots in, a few clicks at a time or faffing around measuring and counting clicks.
The two shot zero is a trick every shooter should know.
