So after trying about 10 different loads for my .54 cal ML and not getting even close to the results I wanted I have decided to go with the old patch and round ball with iron sights. My ML has 1:48" twist and every single load I have ever tried has never yielded anything better than about 6" groups at 50 yards. Here what I have tried so far: 348 Gr Powerbelts 444 Gr Powerbelts Remington Corelokt with sabots (I forget the weight) 3 different kinds of other brands of saboted bullets (I forget these weights too) 400 Gr Hornady Great Plains 3 different sizes of off brand conicals (All these were shot with a scope) I admit that I was not taking into consideration the slow twist when I fired the Powerbelts and the saboted bullets. So I am hoping that the patch and ball will give me a little more accuracy. This gun has made me more angry and frustrated than one should ever be at an inanimate object. I have had this gun since I was 19 (5 years)and it was a gift from my mom and dad (first gun they ever bought me)and I would like to get a single deer with it before I retire it to my safe. I am not happy with it but I take it out every year just for the sentimental value. If I can get a 3" group at 50 I will be happy. Once this season is over I am going to buy a T/C Encore in .50 cal with a scope for rifle season and a .50 cal ML barrel with iron sights for my Mossy 500 for ML season. I figure since the ML season is meant to be "traditional" I will devoid myself of a scope. Anyways I ordered to patches and balls tonight and a set of replacement sights since I have lost the old set. Wish me luck!
