The 25 WSSMwas a good idea but ahead of its time.
I can't see a 25/6.5 PRC having a real long barrel life.
My 25 is plenty accurate.
Below is a 200 yard 0.8 inch group with 115 nosler combined technology silver tip @ 3,300+ fps. It groups like this all day. A good benchrest shooter has had it down to less than half inch at the same range but he's a bloody good benchrest bloke it's all he does tho
