My primary motivation for experimenting with a chassis system had a lot do do with my favorite, hunting style, long range whitetail hunting in the Western and Canada open country. This is quite different from the whitetail hunting that I spent a majority of my 50+ years of hunting, but for sure the most enjoyable, productive, rewarding for me. The approach is to spot/identify a good buck that frequents a particular creek bottom, valley, or slew typically in a hilly/terrain, and select a vantage point that can offer a +1000 yard vista of his territory. There is lots of glassing, gaging movements, relocating/repositioning, and long days/hours of sitting. These bucks did not get big and old by being dumb, usually traveling alone and frequently in heavy cover in the early and late hours. When the shot presents itself, there is little time and re-positioning is usually required.
Shooting PRS during the off-season, the familiarity and advantages of the chassis can be put to use. For example, the ARCA rail system when used either a bi-pod or tripod can quickly by adjusted to provide "benchrest steady" shooting positions from prone through even standing positions by adjusting to the "balance point" of the rifle on a variety of surfaces, as can stock adjustments, accommodating angles, position, clothing, etc. For those that have used a chassis for PRS/competition, a conventional stock design for precision shooting from a variety of rests/positions under time restraints may ultimately feel slow and awkward. Don't get me wrong, my carry/LR conventionally stocked rifle is not being discarded any time soon, but for the type of hunting described above, IMO, the chassis may offer some unique advantages.
