I have three VLP's, two of which are Mod 12's and one Mod 112, heavy, fluted stainless
barrels. Barrel on the .25-06 is broke in with over a hundred rounds. The other two are
getting there. All were MOA out of the box with the bullet/load combinations they "liked".
With the "liked" loads, last time I went out, the 112 got 5/16", the .243 got 1/4" and the
.22-250 got 3/16" (three-shot groups). I'm a pretty happy camper with the VLP's. Even
though they do come with rough barrels compared to customs, and they are a pain to
clean at first, they're come pretty darned accurate.
Unless I had access to a bore scope, I wouldn't buy any known barrel burner used. A
.22-250 with 500 rounds through it without it ever getting over "warm" at each shooting
session would be fine. However, if someone had it at PD towns where he could shoot
at 500 targets in one day could have destroyed the throat area.
