Our firearms of choice are Winchester Browning A-Bolts in 7mm Winchester Short Magnum (WSM). Because antelope are small and thin-skinned, they aren't hard to put down. Adequate calibers include .243 Win., .25/06 Rem., .270 Win., .280 Rem. and the fairly new .270 and 7mm WSM. Sighted-in 1 inch high at 100 yards, our 7s will print 9 inches low at 300. But one has to take into account the wind here in the wide open spaces; a 10-mph crosswind (a light breeze in antelope country) will blow the particular round of 7mm WSM we're shooting about 5 1/2 inches at 300 yards. Bipods and shooting sticks also come in handy on the plains, and a riflescope, of course, is another must. Variables of 3-9X or 4-12X are perfect. For our hunt, we're scoped out with Kahles 3-9X42 AHs.
