I cant say much about the 12 but I own several savages and my .308 is the 10 PC. I do believe it really depends on who responds but I love my savage. I didn't mind the stock, however I felt it necessary to change it for some of the same reasons. I went with the Manners T4A and I really like it. I do believe there are a few other options out there but what limits the options is the bolt release on the front of the trigger guard. If yours is there, you will have a few problems but Manners is one that can fix you up. If it is on top, you will have more options. I think there is only one model 12 with the bolt release in front of the trigger guard however if that is not correct, someone will jump on here and tell you otherwise. I just cant remember.
The savages are great and if you change the stock and bed the action, you will be very happy with it. They shoot very well. I wish I could shoot better, and I know its me and not the rifle, but typical is sub MOA. Range anywhere from .8 to .4 and I have done as well as .361 MOA. That's all stock barrel and action. Only the stock has been changed. Last time I shot I had my best group going, three shots one top of each other, and them I got excited and pulled the last two. So mad but it would have been awesome. I guess that's what keep you going...
