OK now it's starting to make sense to me why all the match guys go for the HPs. Thank you, everyone, for taking the time to respond.
Never considered the supersonic vs. subsonic effect on the tip as Snuffy & Scorch pointed out. And I was confusing SD with CG as Scorch pointed out. Does everyone agree?
There's a gun show close by this weekend and I'm gonna pick up some MatchKings and try to compare them to the A-Max. I said TRY because it's hard for me to tell sometimes if it's me or the load.
Please - anyone else have an opinion let me know!
