Sure there are problems that some people have, some are shooter related and some are legitimate problems and T/C takes care of them. I had a stock split on me also, on my Encore, why, I tightened the stock bolt to tight and caused my own problem. The reason I post that I would like to meet these people is so I could actually see the problems they are having. I have helped quit a few people that have had issues with there Encores. Quit a few times it has been the shooters themselves and other have been problems with scope mounts and just load development problems. Some people just can't get use to the stock on there Encores.
As Bullseys stated, I think some problems come from the forearm attachment method, which I have solved with thin washers between the forearm and barrel. Also, I have seen a lot of guys rest there barrels on sand bags and place the barrel in different locations on the bag and there groups were off. I rest my guns on the forearms, not the barrels. Harmonics will affect accuracy also. Consistency in gun placement while shooting can make a difference. That is another reason I have 5 Encore frames and a barrel designated for each, I get a Encore dialed in and I don't change anything and I don't swap barrels, I keep all the factors the same. That is why I get consistently good shooting Encores. It is not just Encores that people need to set up properly, but any rifle. What happens is, some people just don't want to put the time and effort into there shooting.
Lawful Larry, like me or hate me, it does not matter to me. I am very passant about my shooting and hunting. I may come across as a bit harsh, but that is just my nature. No Sir I don't have stock in T/C but I wish I did. In my opinion T/C is one of the finest gun makers we have today.
