I have had the 64's shoot better in most rifles. And they do as good a job dropping WT deer as the 60 partitions for sure. Nothing like a TSX and from what I've seen of the Amax in the last few weeks it's a hammer out to 300 yards.
Shot my biggest coyote in a while at just over 300 last night. Shot for a further back rib shot and it nearly bust him in half coming out the other side. Hit about 4th rib forward from back slightly quartering towards me trying not bust him up to bad. His liver and lots of other "stuff" were hanging oout of a 6" hole on the other side. He was right at 40 lbs.
Will try for a bigger deer this PM and post results w Amax.
