I dug back through my correspondence with Winchester. I could not find any data for 150s, only 180s. I did find a letter from Chris Herzog, Technical Marketing Specialist that contained the following: "DO NOT seat less than .015" from barrel lands. The data that we have collected indicates that optimum accuracy is usually obtained between .020" and .025"." Also included in the letter is the phone# (618) 258-3568. This letter is from January of 1996, so I don't know if that number would be current; if it is, perhaps it would get you some information for the 150s.

Not a real member - just an ordinary guy who appreciates being able to hang around and say something once in awhile.

Not only a less than minimally educated person, but stupid and out of touch as well.
