What This Means to Varmint Hunters
The issue of reduced barrel
heating for any given performance level is obvious – any experienced
varmint hunter will appreciate the value this provides. There is,
however, an additional and related advantage that is even more significant
to most of us because, for various reasons, we prefer to observe bullet
impacts.
Therefore, let us briefly visit the issue of "felt" recoil. Here, for varminting purposes, I am chiefly considering disturbance to sight picture – how far away must the target be located for the shooter to see the impact? We will surely agree that seeing is everything and the closer one can see impacts the better.
Refer to the following graph to verify that the most rapid rearward acceleration of the gun occurs shortly after the bullet begins to accelerate into the bore. This is true, regardless of how the shooter may hold the gun; inevitably, this is also the interval when the gun is least bonded to the shooter.
