Likewise, the drops at 300m last week were HEAPS less than the ballistics app calculated for the book velocity. So much less drop that I didn't believe it at first and did it again, with the same result. All very odd.

Am going to do some water capacity tests with the different brass I've got, Lapua, ADI, Winchester, see if I'm using cases with significantly less capacity than SAAMI standard.

Got it, thanks!

Strelok reckoned I need to dial 14 clicks at 300m if velocity was 2500fps, but I was hitting very high at that, 7 clicks was probably close. Scope could be doing more than a quarter MOA per click, though is a new Leupold so shouldn't be too far off. Next time at the range I'm going to stay at my 200m zero and measure actual drop at 300 and remove any scope effect. Then I'll see how many actual clicks I need to dial on my scope to be bang on at 300, which is of more use to me than theoretical clicks at an estimated velocity.
