Hi,
If you are like many here on this site, you could end up with a different rifle for every day of the week, maybe even one for every day of the month.
So caliber and style is not critical.
But if you are governed by a watchful wife, you will have some limitations.
As previous posters suggested there is a world of difference between .54 cal. and .58 cal. as there is to ,62 cal.
You can shoot a .45 all day, and powder & lead are not an issue, step up to a .58 and cost, fatigue and recoil all play a roll.
I have a very fine Pennsylvania .62 longrifle that is my go to rifle for hunting, gong shooting, and a rifle that demands serious whomp.
But for target, I go to my .40 cal. very comfortable to shoot, extremely accurate, and does not tire me out.
I am one of those persons that need a different rifle for each day of the month.
Best regards!
Fred
