To All,
My sole problem with the .243WCF is, using JSP/JHP deer-loads on coyote-sized game, that it tends to make relatively a large hole on the far side of the pelt & that isn't easy to patch. Nonetheless all of the factory fodder are good killers on yotes/WT.
(The opposite is the PBCB .30 caliber that I load to the "old-school" 32-40WCF ballistics of about 1400FPS, which passes through both sides of a WT or coyote leaving twp small holes & does a competent job of killing both species cleanly, given a decent/well-aimed shot.)
One wouldn't think that a 170 grain lead bullet only .08 caliber larger at 1400FPS would do as well as a 87/100 grain .243 jacketed SP/HP bullet at twice the velocity on the same species. Nonetheless, that has been my observation over >4 decades.
yours, tex
