I shot the 50s and 45s over the weekend, getting ready for NAC. They have a very similar design to the JTS, but are not the same. They are a bit longer (AEA 45s to JTS 45s). I've also heard the lead composition might be different, but I can neither confirm nor deny.
I'm using a different barrel than when I shot the JTS last season, but I'm really impressed so far. I was testing a couple different pellets, the Zan 56s, and these, so I kept my tune for the 56s. The Zan's did not like this year's barrel at all unfortunately. So... with an inappropriate tune, and in the wind, both AEAs shot well. Shot one card with the 50s @ ~860 fps, 214 I think, and 2 cards with the 45s @ ~860 and ~850, best was a 220 @ 850. I did not notice any bad spirals or anything I'd call a flyer.
I changed my tune for the lighter weight and will be testing these 2 at different velocities, hopefully today. I'm hoping I can find a good tune for the 50s as they should do a bit better in the wind. Might throw a few JTS down the pipe, just to say I did. I had issues with flyers last year, but this is a different barrel so who knows.
