Bob,
I've already got the barrel and it was less than $35 for an unfired 26"er so I'm going to try it. If it only handles up to 168's that isn't the end of the world. I own the reamer so I don't mind playing a little and learning. I'm watching for a deal on a good #2 or #3 for the second pass. Going to contact Boots Obermyer and see if he has a 7mm coming in the future. Also have to decide between the post-64 M70 or the 700 BDL. Or maybe both.
