I have had 3:

350 Rem Mag
6.5x55 Swedish
375 H&H Mag

I sold the 350 Mag after my lovely wife bought me a CZ Model 550 American in 9.3x62 Mauser. I found I much preferred the 9.3 over the 350 so it went down the road. Still have the other 2. I have used the 6.5x55 on mule deer and pronghorn and my 375 has gone to Africa 5 times. I doubt either will ever be sold and I'll let my nephews fight over them when I'm gone. 3 of them want the 6.5x55 so I'll let them fight that one out.

You get out of life what you are willing to accept. If you ain't happy, do something about it!
