I'm looking at buying a 45 caliber rifle. I've had several 458 Win Mags over the years, and managed to sell them all for some reason or another. I have an interest in either a Sako Brown Bear 450 Rigby, or a Kimber Caprivi in 458 Lott. I can get either gun for about the same price, and I think they'd both be nice rifles, but I'm not sure about which caliber to go with. I know the Rigby can be loaded hotter than the Lott, but I'm only wanting around 2200fps with a 500 grain bullet. I feel this is all I would ever need, as far as power is concerned. It appears the Lott is much cheaper and easier to find reloading components for, so that is nice. But, something about the Rigby and the Sako rifle just keeps calling me as well. Thoughts?
