Mixed results - Freedom Munitions .454 Casull 300 Grain Round Nose Flat Point Brass Pistol Ammunition

Good practice ammo. Bought for use in new carbine. Appeared to have flyers all over the place. Figured it just did not like the longer barrel. But, as I tell myself again and again, one change at a time. I went from open sights to mounting a pic rail and open rds along with addition of this ammo at the same time. Ends up the rds and my eyesight just don't parallax well at 50 yds. Haven't re-checked in my revolver yet but appears to function properly. I may be asking too much for flat nosed ammo.
