You can always drive a Corvette slowly, but a Civic can't be reved that high.
:cb2: Obviously you don't have many "Rice Rockets" in your neighborhood. There is just something unnatural about these little Japanese cars outrunning big American muscle cars, but they do so all the time. When I was in high school we all wanted Vettes, Camaros, Firebirds, Roadrunners, GTOs, et al., but the kids I teach today are buying Hondas and Toyotas and trying to break the sound barrier in them. Amazing.
Back to the ORIGINAL question (before folks woke up on the grumpy side of bed): Best caliber for someone new to big bore?
I think that a .454 or .475 is
not the way to go for someone just starting to shoot big bore guns. You don't learn to drive in an Indy Car, so why learn to shoot with an elephant gun?
A .44 or .41 would be the best
for someone new to big bore guns. Some folks here obviously have never felt the need to go with anything bigger. Personally, I will never go hunting in Africa, and probably not spend very much time in Grizzly territory, so the .44 fits
my needs. (I do have one .45-70, but I normally don't shoot hard kicking rifles either. A 6.5 Swede or a .30-30 will kill anything here in Tennessee.) Naturally, if there wasn't a market for bigger guns, they wouldn't make 'em. To each his own.
Once you've mastered the .44 or .41, then you're either happy with what you've got, or, you have something else to look forward to.
OK, I've rambled on enough. It's past my bed time and I probably didn't make much sense anyway. Sorry.
