Chairgun tells me that pellet drop (relative to bore) at 55 yards is about 12" (lots of variables).
If I remember right (which is doubtful), the old .303" bullets used to drop about 12 - 13" by 200yards, and I presumed .308" was roughly the same. As I haven't fired a centre-fire rifle for two decades, I could be talking complete prematurely senile b*ll*cks, though
You is definitely a Londoner, or doing a good impression of one.
.303 and (less so) .308 use quite heavy bullets, both travel fairly slowly in the great scheme of things. If you are really interested I'll go dig out some figures, but a .224 bullet out of moderm CF rifle or 6mm/.243 out of one, will be travelling a bit quicker than the stuff you are used to, and the drop would be measured in 'one hand of fingers' type measurements.
The -20 MOA Picatinny rails I mentioned earlier, might be found on .308 rifles shooting 1000 yards.
