You mentioned earlier that the PH was an A Frame fan .... there’s a reason for that. According to the multiple PH’s I’ve hunted with the AFrame is the bullet of choice and also they have said not to bring NPT bullets. I’ve seen many photos of NPT bullets recovered from buff with zero lead left up front, as PH’s have testified to. Barnes is another bullet I’ve seen highly recommended as well. All the buff I’ve taken have been with North Fork bullets (with stellar expansion and weight retention). I’ve shot a few AFrames as insurance shots and recovered them to find they held together exceptionally well. Please understand I’ve got no dog in this fight, I’m just adding to the experience pool here.
