Personally, I'd go with a .338-06 or the 6.5-06.

In 8mm, I just get some surplus Mausers and be done with that ....... in fact I did .......

The .338-06 is actually about as comfortable with cast bullets as it is with jacketed as well.

The .35 Whelen would be the KING of cast however on an '06 case!!

Have fun deciding .......... if you get "dizzy" just slow down and then lean back into it!! (I know, I'm there permanently!!!)
