G35 - yes, when I say I am swiming - it is a bit slow. However, I want to try moving it forward and trying again - this should correct this.
Devl - Standard RR FF. It is mounted all the way back on the FT - I think I will move it forward about an 1" and try it again.
PPD & Wengv - actually I would *hope* that damm near anyone could do this. Granted, I have put a lot of rounds down range with my M40 clone w/ a 10x to 1k - but still, anyone should be making a 400 yrd shot with this scope - it is that easy.
FWIW - the book Precision Shooting At 1000 Yards notes that in 2000 the world championships was won in the light gun division (similar in weight to an M40) w/ a group of just over a 1/4 MOA (I *think* it was 4.3" at 1k yrds)
BTW PPD - I know what you mean about how big something is or would appear to be at a distance. Several years ago when I first got interested in shooting long and wanted a scope I could not believe that everyone kept saying "get a 10x - you don't need anymore". At the time I worked out the mathmatic ratios - a 4" target at 1k yrds is like looking a 1/4" object at 20 yrds with the naked eye. (Going from memory here on the ratio - but it is close enough for this discussion). Using a 14x was like moving to 17 yrds - the slight improvement in mag could be negated by mirage at the higher power. In short, it has less to do with size of the target as it does with being able to read and understand wind, knowing your drops, knowing how temp, elevation, mirage, sun, shade, angle, and wind (not to mention about 15 other things) all effect POI - it's just practice - lots and lots and lots of practice.
good luck
