'Search' doesn't reveal anything. Does anyone have any experience using, for example back boring reamers to open fixed chokes. I have a few guns that have been redone or refurbished so to speak that are begging to be opened. These are pretty much run of the mill guns (94 Rem, Flues). I'd like to shoot them occasionally but extra full and fuller than that are tough to take. And $45 per barrel is a little tough to swallow at the smith's.
Any alternative suggestions? I'm very open to and in need of advice.
