The .308Win is completely factory except for filling the hollow buttstock with low-expanding foam to deaden sound. The POI does indeed slightly wander a bit with a warm barrel but not enough to cause concern. I'm talking about a 1/4" or 1/2" shift of the entire 3 or 5 shot group at 100 yards, usually up and left, and that's with a very warm barrel. What I'm saying is, shoot a 5 shot group at target. Barrel is now warm, immediately shoot a second 5 shot group at a second target. Compare targets and find the 'center' of each group. The overall group will shift up and left by the fore-mentioned amount everytime. It's not enough to concern me at all. Group size remains the same. When barrel cools down the POI will shift back down and to the right. Hope that made some sense. Actually all I care about is the first and second shot POI from a cold barrel. That duplicates a real hunting situation. I've been told via the internet that SOME Howa/Vanguard/S-W/etc rifles exibit issues with the amount of torque applied to the takedown screws, especially the front screw. Maybe your's is too loose or too tight? My average group size at 100 yards with either 150gr Win PowerPoints or 150gr Rem CoreLokts is right at 1.125" CTC. Some may cry "that's terrible", well I'm honest and that's with factory ammunition with a factory built straight out of the box rifle. I've shot sub MOA (barely) groups a few times but 1.125" CTC is average at this point. Might get better groups if I handloaded or bought premium ammunition. Have shot some groups at 200 meters at another range I belong to the other day. Best group was 1.625" and worst was 3.5625". Most where in the 2 1/2"-3 1/2" range Groups where shot off of a benchrest and some were shot prone and some were shot sitting. I'm very happy. Maybe some think that's great, some may think it's terrible but I don't think a deer or black bear will care. Now my .204Ruger has a heavy barrel and it is 2" longer (24"). Other than that it has the same features as the .308Win. Howa. Same Hogue piller bed stock, blued steel, etc. Now it has a very crappy trigger compared to the very nice trigger on the .308Win. I'll either see if it can be worked over or I'll buy a Timney. It's currently rough and creepy. Was not enough to kill the sale though. Have no idea as to how accurate it will end up being.
