[QUOTE="baldhunter, post: 256967, member: 11853"] I have both the 7mag and the 7mmSTW.The 7mmSTW will out shoot the 7mag,and should,but you have to use the right powder for it to really get it to jump way ahead of the 7mag.I get 3200fps with a 150gr. bullet using IMR-4350 in my 7mag.I get 3450fps with a 150gr. bullet using Winchester WXR powder with the 7mmSTW.The WXR is a double based powder much like Reloader-22.I could only get a velocity avantage of 75-100fps over the 7mag with the single based powders,H-1000 and IMR-7828.I never used the double based powders in the 7mag to see what it does with it.I like them both,but I think the 7mag case is more efficient.
