I am shooting 45 gr. of Swiss 2f , 45 gr. of Goex f3 and 50 gr. of Old Eyes 2F.
In what caliber? Also what twist rate does the barrel have? Pretty light powder charge, especially if it is a .50 or .54 with a roundball twist barrel. I haven't ever seen what caliber you are shooting, did notice it is a GM barrel and also saw where you said your patches are blown up if you go over 55 grains of powder. I suspect you have an issue other than what powder to use. Four things come to mind: something in the barrel cutting the patches, too thin of a patch, patches aren't lubed well or poor patch lube, or old lubed patches that the patch material has started to break down...store bought or your own.I am shooting 45 gr. of Swiss 2f , 45 gr. of Goex f3 and 50 gr. of Old Eyes 2F.
I think most of my patches are a few months old and I did wash the cloth once when I bought it.
I will try the patches I made last week.
Folks like Daryl and Lee Shaver can really help in the accuracy /loading department and do it on a regular basis !This is a bit off subject of original post , however, it is amazing what a little difference makes in a powder.. I guess it could be just by chance though. I shot this group with my 50 cal. roundball Green Mointain . This was after the Lee Shaver 100 stroke 1000 grit steel wool barrel conditioner. I used 45 gr "old Eyes" in 3f. of powder @ 50 yds . There is little doubt this barrel likes 3f more than 2f, and the Lee Shaver steel wool conditioner no doubt helped. The bigger group was Goex 3f and the smaller group is the Old Eyensford 3f. No doubt there is a difference in powder. If I can do this fairly consistent , I will just settle on " Old Eyes" 3f. and be done with the experimenting . If it was not for the low roundball , the group would almost be one hole. The funny thing is , it shoots noticeable lower, but thats ok , the top of my bead is on the bottom of the orange.
