What? Hunted pronghorn in Wyoming for several years. I thought the same way when I moved out there, and foolishly traded off a really good/accurate Marlin 30/30.
Most of my antelope hunting was done with a 243Win. (Rem.788 & then a Ruger77). BUT, the most fun was sneaking up on 'em, and getting within about 50-75yds. before taking the shot. No, it didn't always work, but enough that stalking 'em was a lot more fun than shooting 'em at long range. Longest shot I ever had on a big buck was approx. 225yds.- getting out there, but still within the range of an accurate/scoped Marlin. Sure wish I had kept that rifle. Plastic milk jugs & coffee cans were a 99% sure thing at 200yds. with it. Darn nice wood on that one, too.
