Nevada “picket pins” aka: a type of high desert miniature “prairie dog”.
For global members not familiar with western USA cowboy slang, prairies dogs are not dogs at all.
They are a type of borrowing, ground dwelling squirrel that makes a “barking” sound, similar to what a tiny dog’s sound might be.
Grain farmers and livestock ranchers do not like them, because cattle and horses sometimes step into prairie dog holes and break a leg.
The little rodents are poisoned in large numbers by some land owners.
So, instead of poison, a well placed bullet seems more acceptable to some of us rifle enthusiasts.
The .375 H&H goes clear through the little “picket pins” and it even goes clear through the full size prairie dogs of Wyoming, Montana, The Dakotas, etc.
Unless when I have missed the little critters now and then, I’ve never had to shoot one twice with my .375 caliber rifle.
