Chris, there well may have been, we are an odd breed and tend to respond well and creatively to challenges. I was speaking more in a general sense.
I have seen photos of early heavy barreled percussion rifles--from upper new england
as best I recall that actually had what looked like cast iron wheels attached to the sides of the barrel near the muzzle.
Bench rest had to start some where and shooting from a "rest" goes clear back to crossbow days. After all shooting for group-size i.e. "string matches" goes back to flintlock rifle days as does stump-shooting and chunk-guns. As best I recall, the Berdan's Riflemen/snipers of the Civil War were formed from New England/NY region heavy bench gun shooters.
And there was a real competition/conflict in MANY areas, including competitive shooting, involved in the transition from Muzzle loading & percussion to breech-loading and cartridge as well as the evolution from BP to smokeless. the international long range matches were as much a conflict in the evolution of the rifle as they were a matter of national and commercial pride.
Lets face it, when gun nuts get to tinkering strange things happen.
But just for added consideration; we need to remember that "original era" schutzen also involved beer, AND GAMBLING. Though we talk about it less-----betting and side matches were a much larger part of the shooting game that we consider today. the "professionals" who traveled the circuit probably make as much if not more off the gambling as they did in actual prize winnings.
Given humane nature, if we all put 100 bucks in the pot at a given big match with the winner getting the lions share; it'd probably inspire a lot of creativity and rule bending (
I picked 100$ out of the thin air as an approximate WAG for the difference of inflation over 100 years)
