You should see the variance I get from speer sp bt 180gr. I don't know why but even though they show the most weight variance my rifle likes them the best. Strange thing this reloading is.

I shot a 1/4" three shot group yesterday with them. Doesn't happen everyday but usually under 1/2". If I try to shoot an accubond of the same weight the best I can do is 1 1/4". I'm not sure why but it is what it is.

BTW - This is a Ruger in 300WM.
