RLH, are you using the new Triple Shocks or the standard "X" bullet?
I must lead a charmed life with Barnes.
My first "X" bullet, a 150gr., shot a 5 shot group in the 3's using 75gr of IMR4831, Fed primers, out of a fickle .300 Win mag, that dont like anything other than a Sierra MK. The guy that sold them to me said that some like em and some dont.
Understatement, to say the least.
