Dang. I wish I lived where you guys live. On most guns the Gander Mtn's prices near me are typically equal to or quite a bit cheaper than any of the LGS' around here. Admittedly I haven't bought a new gun in awhile, but the last two I did buy were at Gander Mtn. A brand new stainless Ruger New Vaquero w/ 7.5" barrel in .45 colt. Cost me $329.99. And a SA M1A Standard for $1399. LGS was asking $1599. Recently they were selling Walther PPKs for $559. Every LGS I checked was around $700 and up.
I rarely buy ammo as I reload. But, I never bought/buy ammo from Gander or the LGS as both are equally expensive.
As for reloading gear, the Gander Mtn near me no longer sells any of it and even when it did, the prices and selection were dismal. Only one LGS that I know of near me has a few items, but its overpriced and most of it has literally been sitting on the shelves for 20+ years, judging by the labels.
The one store that always trumped both Gander and the LGS was Sportsman's Warehouse. Selection and prices for ammo, reloading gear, and guns was always better there. Unfortunately they closed the one in my neighborhood and the nearest one now is about a 30 min drive. Not bad, but I rarely get up there anymore.
