What caliber of rifle do you recommend for pronghorn antelope?
 

My personal favorite is a 7mm STW but .270, .280 and .300 WSM are also excellent choices.

My opinion is that you should choose a pronghorn cartridge on the following listed by importance. 1. One you shoot well and are intimitaly familiar with its trajectory.
2.Accuracy (rifle,load,scope combination)
2. Flat trajectory
3. Good wind bucking qualities
4. Terminal effectivness
