I had about 12 rifles a couple years ago, I am down to 5 nice outfits, putting a 25-06 and a 260 up for sell to buy a 6.5 prc - so I will have 4 - 223, 6mmCM, soon to be 6.5 PRC and a 270wsm. Several of those I recently dumped were 300 mags (rum, wby, wm) and a 325wsm. After I saw the 270wsm hammer elk, I decided to dump my big mags.
I am only in my 30's, but don't see the point in having guns that dont get shot unless there is sentimental value. Instead of giving my kids my old guns I have been buying them their own as gifts- something cool that they can be proud of and they have input in. My 12 yr old is so proud of his 6.5 creed with the zombie green boyds at one stock - way more exciting than my old savage 110 270 that i bought when i was 14 that I could have given him instead.
