I spoke with one of the guys at VQ a couple of weeks ago and asked about the bedding system for my 77/17. He said he has used it and heard of some others that have also.
I must have gotten one of the exceptions to the norm as far as accuracy goes. Patterns looked like spray and pray groups. I pillar bedded mine, bedded the barrel to the balance point, free-floated the barrel and have ended up with a pressure pad. The groups began to tighten, but not what was expected. My last effort was to buff the bore with Flitz and apply Moly-Fusion. The groups now have all holes touching....but this is at less than 100 yds. Need a weather break to get to the range to see what it is really doing before I pitch this factory barrel down the hill and install the GM barrel patiently waiting its turn to play.
I have to admit though, I sure have learned some new things. Good luck. What barrel are you going to use? Let us know how it works out.
