Jet,
I've no experience with the A-Frame, but was very pleased with the Nosler on my first PG hunt(using a 9.3x74R). Ten critters, and only recovered two bullets. They were pealed back to the partition, and retained around eighty percent, as JB described. Only two critters were not one shot kills. I fired a courtesy round into the kudu(it dropped instantly to a double shoulder hit) as the lights were still on, when I walked up to him. The other was a zebra, that I just plain flubbed shot number one. I'd use them again.
Jeff
