.... Being steady at 100 yards is much different and more difficult than at 50 yards...
Target distance has no affect on steadiness.
But the wobble is going to have greater effect on pellet impact point as the distance increases. It's the whole minute of angle thing, 800 yards and 1 moa is about 8 inches, 100 yards and 1 moa is only about 1 inch.
If the end of the barrel is swaying around, say, 1/4 an inch, that'll put all the impact points at 50 yards within, say 1 inch. Same 1/4 inch muzzle sway is going to spray them into a larger sized group further out at say 100 yards. (Theoretical example of course).
Not sure why you two think you've gotta keep crapping all over anything extreme field target related.
Again, come on down and shoot a match. We're obviously doing it wrong so come show us the right way, in all aspects.
You'll be treated alot more warmly and welcomed much better than you've done to extreme ft-related topics here on the forum.
You might even have some fun, although from previous debates it seems that's not really the draw of competition for you two.
(I'm all for welcoming constructive criticism but the passive aggressive attitude towards this is getting old, just like it did a few weeks ago.)
