Just want to share a handy tip I employ when out shooting.
As I shoot a number of calibres, remembering all distances & trajectory data for each is improved by writing this onto some first aid tape, and sticking it to the stock below the scope, or around the reticle.
Its an easy lookup, and states the proven zero +/- ; reducing mistakes or poor shot placement.
I do re-zero weapons from time to time, and at new distance depending on quarry and terrain and it ensures I keep up to date with changes each time weapons come out of the cabinet.
Enjoy, trust its useful
Just to clarify: I dont go shooting with more than one weapon at a time for very obvious reasons !; I can see that could have been miss intepreted.
