I've always thought the lighter rifle should not shoot as well in the field, but my informal comparisons have not supported that. I've shot groups at 100yds offhand with the 84M and with a much heavier rifle. Really no meaningful difference. I do think long range where you can use a bipod or rest is better (easier) with the heavier rifle. I'll have to play with this more and come up with a more definitive answer.
