Thread: Any neat tricks?

Ok so I muffed the chance at a wall hanger yesterday. Kinda a long story but the short version is:
Big sika stag answered a single call then came charging over the brow and stopping in clear sight at 300m.
I tried to dial the elevation on my CDS turret only to find I didn't have enough rotation (only wanting 7moa) so obviously had done at least one, maybe 2 full rotations from zero.
I kinda panicked and cranked it back a couple (maybe three) full turns but then the dial would still go round but kinda grind. I put the dial on zero, lined up on the big boy's front shoulder and hoped.
The suppressed shot didn't even worry him, he stood for a few seconds before nonchalantly trotting into the scrub. I saw him a minute later standing not 100m away without a care in the world.

Question is, do you have any handy way to ensure you don't lose your zeroby being a full rotation or more out?
