Whether a person has one gun or a quiver of them, I think the biggest factor has to be being proficient with what they shoot. Practice, practice, practice can only help a persons odds in success. I've had a Winchester model 70 in 30-06 that I've had and hunted with since high school. I resently bought a Weatherby in 7mm Mag and I plan on shooting it at the range weekly to get proficient with it.
Having one gun or a quiver of them? I don't see a problem, it seems like more of a blessing to me to have either option. I hope it never will end.
My elk rifle is a M70 Winchester "Black Shadow" with Leupold VXII 4x12. I paid under $400 at Bi-Mart back in 1998, It is my newest rifle. My only other rifle is my M70 in 25-06, I've been hunting with that rifle for over 30 years now, the last thing I took with that was my Big Horn ram. I guess I'm not a big gun buyer.
I have had the same rifle for 19 years, never felt the need to change. Weatherby mark V in a 338 win. I have it set up with a Zeiss rapid z 600. I mainly archery hunt now, but the 338 has never failed me and is a one shot wonder. I have done well with Hornandy 225 gr and currently have Barnes loaded up for the next rifle hunt, whenever that may be...
