[QUOTE="Namibia, post: 396415, member: 20207"] Good evening Gents, Can someone maybe assist me with the following problem. A friend of mine reloads for a .300Win Mag. using Sierra GK 180gr, and Prvi Partizan Brass. He assured me that the charge is well below max according to the manual. (I don't have the exact charge and type of powder though) After firing his loads, there's quite a bit of powder fouling on the shoulder area of the case (on the outside of the case, off course:)), as well as on the neck area. Seems like some of the gas is leaking "back" past the neck during firing resulting in a "burnt power residue". This doesn't occur further down the case past the shoulder egde. He shoots a Ruger M77 Hawkeye, and the rifle is brand new. Your imputs will be much appreciated. Thanx Pieter [/QUOTE]
