I don't have the targetvision but I really, really, like my AMP annealer. I no longer have to deal with or compensate for any kind of spring-back, and the consistency seems to be spot on as far as I can tell (no rockwell hardness tester here). I anneal every firing (if you have an AMP why not) I'm getting .24 MOA groups (ES of 7-9, SD of 3-4) out of a factory RPR in 6.5CM with my handloads, I know I got lucky and got an excellent factory barrel, but even with a good barrel most people can't get that kind of accuracy without good consistent loading practices. I'm not going to try and sell you an AMP, but there is my .02.
