My confidence with the 06 came from shooting a variety of loads at distance and trusting an elder with many years of experience hand loading. The load is Nosler ballistic tip 180's with accurate 3100 ( discontinued now ) moving 2900fps. This load got my first elk broadside at 407 yards straight through the boiler and my first deer at 466 yards.
I was looking at your sig, and I thought that this might sound better.
When it's time to bury your guns, it's time to use them.
