Sir Bevan, That Buffalo Rifle by Lovex sounds good. I have always found AA-5744 at my local emporium. AA-5744 and H4895 are both great for reduced loads. AA-5744 is great for max loads with 250-gr bullets and H4895 is great for max loads with 400-gr to 750-gr bullets ! The mighty .458 WinMag could subsist well on those two powders only, but it is so exceedingly versatile with so many bullets and powders of all types ! More than I could shake a stick at.
