"Ask your local gunshot how many 270s he has sold lately......not many Ill bet. "

Wow, you'd be wrong there. I do gunsmithing for a few shops in central Wyoming and I know what's selling here. The 270 is the 3rd or 4th most popular big game round sold in all the gun shops and also in the local Walmart.

In center rifle rifle ammo 223 is #1, but by far most of it's not used for hunting big game.

#2 is 308 followed very closely by 30-06 and the 270 Winchester is #4.

So for hunting of Deer and larger game, in Wyoming at least, the 270 is in the #3 place and in overall sales of center fire ammo it's #4.

Gun sales are slightly different.
223 is still the #1 seller. Mostly AR15s and a few other military style rifle.

#2 is the 30-06 and #3 is the 270.

#4 is the 308, but again many of these rifles are military style auto loaders (20 and 25 round magazines) which is when those rifles are being fired a lot more then the 30-06 and 270 bolt actions.

So ammo sales do not reflect gun sales exactly, but they are fairly close.
