I don't know Jim... the old rifles we have hunted with over the years tend to become as dear to us as old friends.
More than once have I slipped the safety off the 'new' rifle and for a split second felt a bit of quilt because my beloved, dear old friend was tucked away in the safe.
I think it is normal as I have heard this from more than a few other hunters/shooters. " I feel bad I didn't shoot this deer with ol' Bertha" echoes the remark of a close hunting buddy as we muse over the days hunt.
My brother is a 1 gun type guy, as I have been in the firearms business for years, he has had every opportunity to acquire many firearms at the right price, to say, but is loyal to his circa 1971 BDL 7mm Mag.
The blue is worn off the bolt knob, the stock has battle scares all over it and the old girl is starting to show her age as far as accuracy goes. But, he won't put her away.
Me on the other hand, I seem to hunt with a different rifle every two or three years... but I do have one I hold dear to my heart, good ol' Alice, together we have pulled off some pretty miracles shots over the years... and missed some pretty close and easy shoots also... but that wasn't Alice's fault!
