Horizontal rain: compensation factor?

Well oomans, it was a bit yukky at Kingsbury A this morning: only just daylight at first round and pretty gloomy for the rest of the morning too ! The rain was coming in horizontally, blowing straight down the range from the butts to the firing point, and so heavy at times that the targets themselves were only just visible. Several times the RCO fretted and pondered abandoning, but didn't. He can be cruel at times...

We puzzled ourselves.

At 300 mards*, our first distance, we were struggling to keep all our shots in the 4 ring. We were shooting a P14 with our POSP 6x42 scope, and usually do better than that. However, when we moved back to 500 mards, we were always in the 5 ring and usually in the V bull. We didn't adjust anything, correcting for distance by dropping down two chevrons on the scope reticle, and possibly judging the wind a little better. The shooting conditions hadn't improved, so why did our shooting ?










*Kingsbury is one of those ranges where the Army didn't go metric as such: they just painted over the distance markers with a 'm' instead of 'yds'

Simples smile2 . . . . . by the time you moved back to 500 mards your luxurious furry coat had absorbed so much rain the extra weight was helping to steady the boom stick :good:

The speaking of stability, could it be that the bullets were more stabilised by 500 m? We would have thought that 300 m was ample enough distance for them to stabilise. (The rounds were standard German surplus 7.62x51 - MEN)

Good brass for reloading. Don't waste it.

We don't reload, ooman. Anyway, we thought MEN was Berdan primed?

Berdan primed cases are quiet reloadable.
