I suspect running the higher node makes a difference, even if only a very small difference. A point or two is often enough to make the difference between winning and not winning. Nonetheless, it hurts every time I buy a new case of Lapua brass.![]()
Yes, no doubt if you shoot F/TR seriously these days, every last point and 'V' ('X' to you) counts and you do notice the gain of that extra 75 fps or so MV over a series of matches. It's the difference between one of those frustrating days where there are few Vs and a lot of 5-ring (10-ring US) 'linecutters', but those that miss the line barely fall outside, and those gratifying tricky-wind days when a worrying number of shots are on the line or barely in, but when 20 rounds have gone downrange and you breathe a sigh of relief (and marvel at your luck) that they nearly all fell right-side of the line. This may be more marked / noticeable for us in the UK (and Canada) with our pairs/trio shooting with more opportunity for wind changes between shots than in string-shooting.
