I'd have to say I was a big fan of 25 cals for a while as my first rifle was a 303/25 (303 Brit necked down to .257....a popular Aussie wildcat).
I've also got a nice little sporterised Martini Cadet in 25-20.
And I'd be lying if I said I wouldn't like a nice original Ruger Model 77 with the tang safety in 257 Roberts.
But I bought a Tikka T3 Lite Stainless in 9.3x62 about 18 months back and my passion for 25s has wained.
My love affair with 9.3 cal was confirmed when I took 4 goats with it last hunting trip.
Off the bench it isn't real kind but in the field you don't even feel the kick.
I think the only other love affair I'm going to have is with a nice 7x57 of some description, preferably a CRF bolt gun or perhaps a Ruger No1.
I bought a 450/400 NE 3" and it's fun but is too big to be a regular shooter (I know, like 9.3mm isn't!) and I reckon real love affairs are founded in cartridges you can use on almost anything.
That's what I really love about the '62.
Use the right ammo and place your shot and there is probably nothing on earth that will not drop.
Alternatively you could just as easily use it to thump foxes although the pelts would be a little ruined.
I know the same could be said for 375 H&H or even 338 Win but I reckon the 9.3x62 has an old world charm about it and let's face it, would you REALLY want to use an H&H on a small predator?
