I lean more towards classic although there are some wildcats that interest me. I'm not into short magnums although that's always subject to change. And then there's those "just because calibers/guns as Hookeye stated. Sometimes you just have to have it.

How about improved?
On a classic to spice it up.

Heartily serves one or many.

Nearly the equal of the .300 Savage-Thinking about doing this one day. Sometimes less equals more.

Shoot......I like anything that goes BANG! But I'm sort of like Oldtimr. I have a love affair with the .45-70. I own 3 of them and shoot and hunt with them a lot. Those and my black powder rifles. The only time I don't use them for hunting is when I hunt where a 200+ shot is likely. Even though the old 45-70 can do it the trajectory of the bullet makes life difficult. At time like these I grab my 30-06.
But I've played with the WSM line of cartridges and had big magnums. But they've all come and gone. The little 7mm-08 remains in my safe because its a great cartridge and accurate.

Well I shoot a 6.5x55 Swedish, a 6.5x54 Mannlicher Schoenauer, a 9.3x62 Mauser, a 375 H&H mag and when I had a double rifle it was in 450/400 3 1/4 Nitro Express. So my vote goes to hunting with the classics.

the old 300 H&H mag is a classic. when one of the gun companies produces rifles in the 300 H&H they don't seem to stick around for long.

I occasionally use a 30-30 lever Winchester but I seem to go back to a bolt Mark X in 30-06 for my deer hunting. I have others that I do not use, a 6.5X55, a 7X57, a 303 Enfield and a 9X57 Mauser(ammo too scarce and expensive on this one). It is hard to beat the old 30-06 for an all-around rifle.

Handload. You can take 7x57 brass and run it through an expander die to bring it up to 9mm and several places make 9mm bullets for it and in many cases you can use .358 bullets (slug the barrel first) in it. Get a set of 9x57 dies and you're in business. Problem solved. In a snap you could also use 30-06 brass since the 7x57 is the parent case for that caliber.

I'm using my 280 Remington and 35 Whelen more these days. I did take my 25/06 and 257 Weatherby to Wyoming last year for antelope but missed my 280 and will take it this year. I guess I just like to use the less common rounds.

Actually Flags, the I don't want to take the 9X57 to the woods also. It is one of those Emil Ketner jobs made between the wars in Suhl, Germany. A nice old gun that I want to keep in good shape.

I'm pretty much into .30-30's. I love a good .32 Special and .35 Rem too.
