Last year I bought a new traditions pa pellet ultralight. I know it’s far from traditional but it is what I could afford. Basically it’s a flintlock with a barrel off an in-line. When I got the rifle I picked up some 777 (loose)and some hornady 250gr sst sabots. The rifle groups great at 50yrds. The problem is it’s high, very high. Target had a 5” bull and with a 6o’clock hold poi is about 6” above center with the sights adjusted all the way down. At 100yrds they hit about 2” above center which is still 5” above hold. I’ve tried from 70-90grs of 777 and group size stays the same just moves higher. I still need some more time at the range to play but I need to decide what bullets to try. I’m thinking heavier and probably full bore instead of sabot. I’m also concerned with bullet performance on deer. I know with a 1:28 a prb is pretty much out at hunting velocities. Can I use a lead bullet or will they slip the rifling? I should probably mention I’m using fffg 777. Honestly I’ve always used fffg, that’s just how I was taught, this is my first attempt with 777. Any recommendations would help.
