New pa pellet ultralight issues or load choice?
Just got a New traditions pa pellet ultralight 26” 1:28 twist. I’ve fired it about a dozen times with no failures except one flint issue( my fault). The ignition on it is great. My problem is it doesn’t hit where I’d like it to. Grouping at 50yds is great 3” or so but point of impact is high. About 8” above point of hold with the sight blade lowered as much as possible. I’m shooting hornady 250gr sabots and 3f triple 7powder. Owners manual shows recommended load of 65-100gr with a 240gr sabot. I tried 80gr and as much as 95 but hits in the same place. I’d like to keep the speed up as much as possible for flat shooting and expansion. As it is now I’m about 4-5” high at 100yds with a 4-5” group. Ran out of range time and don’t have a chronograph so I was hoping someone might have some insight. With the barrel on this flintlock it should take similar loads to an inline. And info would help.
