"Not to disparage your good group, but with only three shots there is a good probability of chance that increases in proportion to how accurate the rifle is. How about shooting a five shot group to rule-out chance."
hey, how about 5 round, 10 round, 20 round groups?
just kidding.......i have 3 weatherby vanguards in 243, 7mm mag and 300 win mag and all of them shoot like yours. congrats on your weatherby, your gonna like it
