A 610 4" would be sweet, but so would a 41 Special in that platform, or a 657.
All that said about me not wanting to shoot watered down loads in my 10mm, I still think a 45 Auto-Rim in a handy 5" barreled revolver would be fun as hell, even though their are 44 Mags, 45 Colts, and a FA 454 here.
250 gr hardcast at 1000 fps would have to be loads of fun, not to mention very effective on deer and pigs.
