Planning a hunt to Africa with my Dad in a year....(may be our last hunt together)...anyhoo...I'm taking my Model 70 375 Wthby as a "General Purpose" rifle and am torn between the 416 Rigby and the 458 Lott. This will be a Ruger #1 either way...that's been decided. (Used them on the big bears while in Alaska) I can wring the same accuracy out of both of them..Trying to decide which to leave in the gun safe. Checking out ballistics...a 400 grain out of the Rigby can be boosted to 2600 fps...almost Wthby velocity. Makes it flatter shooting than 375 H&H. Just having a hard time figuring out what I can expect from the Lott. Any suggestions / information offered would be greatly appreciated!!
