With all the .204 factory ammo available, I'd try something else, mine doesn't like the 40gr Hornady, either. It shoots the 32gr best. I've also tried the Winchester silver box, HSM and Remington. I'd like to try the 34gr Winchester whitebox, too, but it wasn't available at the time. I've since decided to handload for it since I'll have so much brass for it once all my factory ammo is shot up. The .204 Handi is just like any other Handi, you gotta find the ammo it likes or handload for it. :wink:
