I doubt anyone’s had any experience with them. Have you shot them yet? 3 ounces for a turkey?! Is that what you bought them for? That’s crazy. So is the price. $5.36 a ROUND?! Plus shipping! What make of gun do you have?
I think I’d be more interested in selling that ammo instead of shooting it. You’re going to want to shoot some of that other ammo first and work your way up to the 3 oz stuff. The foot pounds of energy is 4197. That’s similar to a 300 Weatherby magnum round. Congrats on the good deal.
Shot a 10 ga. once at a sportsman's club when I was 16 and full of spit and vinegar. An old timer handed me his shotgun and said "try mine" . One shot, returned to my original position and handed it back with a "thank you sir" and never fired one again.
