Well I have a few shooting sessions at the range in now with my 29sf. One thing I have noticed is that the DT hard cast are not very accurate or at least not as predictable as the other stuff I have shot. I've probably put 500 rds through the gun now and after about 200 it settled down with everything except the hard cast. I used 200gr and 230gr of which 230gr was the worse of the two. Even the 200gr was all over the place though. So in cruising around youtube and watching hickock45 I see that he has the same issue and when he puts in an aftermarket barrel, the hardcast settles down too. So my thought is to go KKM. When I called them, he told me they all come 4.7" and they will cut them down for no extra charge to whatever size I'd want. I know the longer the barrel the more fps but I also like the compactness of my 29sf. Has anyone else had this dilemma and thought through it? I'd like to hear your thoughts on it and why you decided what you did if you'd be so kind as to share it. Thanks in advance for any help.
