This is a pretty scholarly article with a lot of big words that I am not familiar with. I did a quick research on "prion" and I guess they are the agents which can cause certain diseases (including CWD) if they are in a "misfolded form" - not formed in a normal way.
I'm thinking that one of the reasons for the presence of clay being a contributing factor is that clay particles are very small compared with sand particles. Consequently, they pack together more tightly and reduce the ability of the soil to drain well enough for these nasty "prions" to leach away as they might in more sandy soil. When animals such as deer eat this soil in the normal process of browsing on forbes and grasses, they ingest the prions and become infected.
OK - I think I'm a little smarter now. Thanks for the report.
Thanks for the translation and summary. Makes it much easier to understand that way. I do have interest in this subject now but it's hard to understand some of the technical stuff that gets posted on it.
Others have offered up a sighting of roughly 2 inches high at 100 yards as a good sighting scheme. In my own experience I have come to favor a sighting of 3.5 inches high at 100 yards. This allows for the individual to hold dead-on (directly in the middle of the top and bottom) the animal out to roughly 350 yards.
Magnum calibers such as the 7mm Remington and 300 Winchester will extend this slightly. At 400 yards I hold directly on the backbone of the animal. The drop at this range allows the...
