And if it does ?.....surely you find your most accurate load by shooting groups, settle on one, then chronograph the load to get a speed to develope a drop chart, then finally set your scope zero at whatever range you choose ? ...... a slight POI change whilst chronying the load....does it matter??
Looks a good bit of kit, less leads, parts, no tripod etc.
