Just get the set. It's cheap, only a few dollars. You'll need most of them sooner or later. Be warned, I broke one (not on this job, but on another gun) of the smaller ones so be gentle.
I'm so glad somebody posted this! Hell, I'd like to find something that had at least 500 yards CLOSE to Baton Rouge! (Not Donaldsonville either!) Anything like that around Denham Springs? I need to site in my new rifles!
If not, we need to all pitch in (us local to BR area) and purchase some...
