I saw some reloading data at Alliant's website and it listed that with a 139 Hornady SP i should use 67.5 grs of Reloader 19 to get 3260 fps with a 7mm Rem Mag. Can you substitute 140 grain bullets instead of a 139?? Also when reloading data says they used a 55 Nosler Ballistic Tip can i use a 55gr SP??

Why work when you can hunt???? Heck why work at all!!
