Well, apparently, dad and his friend went ahead and braved the cold and ice yesterday afternoon, in order to start getting the rifle sighted in. Initial sight-in was done with Remington UMC 55 grain FMJ's. They didn't really go for maximum accuracy - the plan was to get it on paper at 100 yards, so they could start working up some test loads for it. Anyway, 3-shot groups were all under 1". Both said they were pretty impressed with it, considering high temp was around 10*, and the picnic table we use as a shooting bench was covered in ice. General consensus was that groups would likely have been a lot better, if shooting conditions were better. I will press for more details, when I have a chance to talk to them about it in more detail. To be honest, hearing this report, I'm seriously tempted to order one of those barrels as well. Price is very good, and I believe they have some holiday discount codes that could be used to save even more on them.
