Muzzle weight helps for offhand shooting, which is why the exaggerated Olympic-style of Standing, shooting.
The Olympic Shooters of the 19th, 20th and 21st Centuries have all copied the 18th & 19th century Swiss form
of holding rifles for standing shooting. The 'offhand' is holding a palm rest, or is positioned just in front of the
trigger guard, thus accentuating the muzzle's weight, in effect increasing the muzzle weight which makes for
steadier "standing or offhand" shooting.
If a rifle is too light for good holding, replacing the ram-rod with a steel or brass one, will help increase the fore
-ward weight. I have done this myself when younger, however now almost 70 yrs old, I find those "too-light" guns
hold much easier and the original wooden rod works just fine.
Back at "the turn", Harry Pope used to say that a woman's offhand rifle should weigh 12 pounds, while a "MAN'S"
offhand rifle should weigh 16 pounds.
My best-ever 100yard offhand target scored 99/100. I used a 22 pound rifle, but, I was only 23yrs. old & considerably
stronger than I am today.
