Thread: Pressure.

Still new to the long range game. How important is pressure whem setting up shooter? I was just running some numbers and cant get them to match what was happening last time at the range. If im not doing huge alltitude changes can I leave it set at one generic number? Or do I need someway of getting an actual reading. Cheers.

Depends how far you're shooting and what the calibre bullet combo is basically

.284 with a 162 is you right? Won't be a huge deal of change normally to 600+ sort of ranges


How much different are you seeing? So many variables to account for

Um like 1 moa @500 meters consistanly 1 moa. Im thinking I need to recheck my zero distance which is normally 200 but i moved my scope back for a better fit and when I resighted it i just put it bout 2.5ish high at 100.

Problem likely found. Zero for exactly 100 and then if you want to have a "point and shoot" zero for walking around, wind it up to your 200m elevation or wherever.

Scope Center to bore height is often overlooked and will add continuous error.

Yeah not many people measure that accurately. I have it written down somewhere for my rifle but I think it's 48mm.


If I use the standard value in the field in most calculators instead, 38mm (1.5") I get no difference in actual corrections, it's less than 1 click value at 1 kilometre
