Just for the record and to throw another cat amongst the pigeons.
In theory 40fps variation down range would equate to massive POI changes and 40fps shot to shot variation would equate to massive POI changes, agreed?
Well how come then when admittedly this isn't air rifle related but still related to slinging lead down range. How come when using centre fire rifles (in this case 250gr .338 lapua) extreme spread over a 5 shot string was if memory serves me right around 50 fps ( chrono was approx 5ft from muzzle) yet the rifle(s) in question was still producing sub 1/2"MOA out to 800y and then around 1MOA at 1000y.
So in theory these rifles shouldn't of grouped as well as they did, somebody with far more intelligence explain that to me please.
