Well, after lots of reading posts, other stuff and talking to others in my area this is what I did. History: New rifle had void in barrel and was sent back, out of box for new barrel. Replaced without question. Received and cleaned initial cleaning. Not sure how many rounds factory put through it, but it had lots of hard fouling. As recommended by someone on the post here, I loaded up some Sierra FMJ to put down the barrel with cleaning after several groups. Was not concerned with grouping. With spotless bore, loaded up some 1390 Sierra HPBT w/36.1 grns Varget, and shot several groups. Smallest was .680 largest about 1.25". Cleaned again and found quite a bit of hard fouling. Loaded up recommended rounds from SSS, Tubb's Final Finish and fired as instructions and recommendation from factory dictated. Cleaned spotless and loaded up the same 1390 Sierra load again. First two foul the bore shots cut the same hole. The three, three shot groups fired following the two shots were right there, with the largest at .405 and the other two at 1/4" or less. Cleaned the bore, and the fouling ( extremely light) was removed in a few patches. The throat was moved fwd a few thou. as "Brand" at SSS said it would, but has not affected my ability to load close to the lands should I chose to do so. Patches pass much smoother than before, fouling less, and accuracy is there. I am happy with the performance of the product in this application as well as 7mm Rem. Mag. (Rem. 700 Classic, old model) as previously described. Following the application of The Final Finish my best group with the 7mm was .375 ctc. This is after new load developement using Barnes bullets and shot a few days ago. Right thing to do??? Maybe, maybe not, but the product performed as advertised and I am happy with the results. I would use the product again. For each application, I have called the tech folks at SSS and taken their advise on use of the product for each rifle. I haven't gone wrong using their recommendations at this point. I set this rifle aside for varmit application only, and have a Zeiss Conquest 6.5-20 scope on it. I would not normally use it for large animals, but I have just undergone cataract surgery which did not allow the use of my large bore rifles until recently for deer season. I shot a beautiful 3x7 buck with the 12BVSS at 135 yds 4 inches below the skull at the spine, which became two inches shorter after the shot. With the accuracy of the rifle, I did not even hesitate with that shot. Probably the last large animal that will fill my scope using that rifle, but it worked for me this once.
I appreciate all the input and advise received on the subject, but sometimes we just have to find out for ourselves with all things considered.
