If 5" groups at 25 yards is your benchmark then most of today's makers should be capable. Any manufacturer that is worse than that has either been weeded out of the market or the gun you got is a lemon. I'm guessing most of the guns in the $600 to $800 can meet that standard. If you can spend a little more than $1,000 i'd just go with a Colt Gold Cup. If you've got a couple grand than any of the custom makers out there will be able meet your needs.
