RinB that is the truth about any animal...and if you want to have 1 or 2 guns for everything, I'm not going to talk you out of it. By the same token, its FUN to have specialized rigs for specific tasks. I'm using my 30-06 here in a few weeks on my next antelope hunt...doesn't mean it will be my go-to antelope rig.
You can survive on bologna, ramen and PB&J for many months....but who wants to?
N'er mind the naysayers..build what you want/like. Getting close is fun and long range is just as fun. For the critics let it be known I have killed them with revolvers as well as long range rigs.
I just got mine done on a 700 SA in a 6.5x47 Lapua. Had fun this fall with the builders 6mm-06AI. Actually had a LOT of fun with it. Let several of my friends take antelope from 450 to 930 yds with it.
It is all about what you want not the knuckleheads here.
