True, a .500 Nitro should be pretty handy, even in a D weight barrel. The .475 Turnbull, with its 26" C weight barrel, handles very nicely.
The .450 Nitro was made previously in the Bodington series, but they are hard to find. The .458 bore gives you many bullet options, so it would be useful.
I bought a K1V .223 last year and a 1A 7.62x39. Both shoot well. Still like to get a .257 Roy.
