It shouldn't be too tough to do but I need my 300 Whisper upper reamed to 300 AAC Blackout so I can use the cheaper ammo, especially it's high pressure versions.
Re: Who can ream a 300 Whisper chamber to 300 AAC?
Yeah, i know it's not much work. And it looks like the reamer is on sale for $125 right now. I just have the one upper and really don't plan on getting another so I'd rather find someone local and get it done for $40 or so.....but if I can't find anyone to do it, it may be an alternative.
