I'd just like to add a few things here. There is a tremendous amount of misinformation concerning hunting guns made in the 18th century in the German regions. Ive spent 30 years looking at these things when everybody else was looking at guns made in North America.
"Jeager" have no more or less wood than is necessary to build the gun. The hunting guns are light weight and handy. The barrels have large breeches and bores and rapidly tapering swamped barrels that remove the weight. The off hand target rifles are heavy, most I've sen were around .45 cal. They still have slightly swamped barrels, but they were definitely building the weight in on purpose. The target rifles are as slim and racy as the barrels will allow. The bench guns can be real whoppers in the 20lbs + range and large calibered.
There are some really awfull representations being built today being built by people who have never handled the antique guns in person. Take a thumb through in Shumway's VOL I and look at the dimensions of these guns. Yes, they may be slightly larger in some dimensions, but they are compensating for a massive breech. Today's uninformed builders have this mind set you have to leave all kinds of extra wood on these guns. Nothing could be farther from the truth.
The earlier (pre 1700 more or less) can be a little pregnant in the buttstock, butt not the horrid exaggerations that are made today.
