Regardless of caliber, I use the lightest gun I can find as long as it is accurate from a cold bore.
My .338 or 45-70 will really get my attention, but I go under the theory that I carry the darn thing more than I shoot it.
I don't know exactly what they weigh, but I am pretty sure that neither is over 7 lbs. fully loaded.
Yeah, they kick. But, like I said, I carry more than shoot.
