I love my 452 Trainer with a Simmons 22 mag on it. Just ole Federal champs gets 1/2 at 100 and goes thru 2x4's. That Scout has a shorter barrel, so try it up against a longer barreled one and you'll see the difference. But I'm sure the 39 A is great too. Whatever puts it on the table is good.
We are all winners, for we are the sperm that beat everyone else to the egg.
