Got the new stainless barrel from Douglas. Other than being stainless, the specs are the same, it's a 10" with 1 in 7 twist. The results are looking better, but I'm still not sure. I have some targets from today:
The 240's appear to be ok at 10 yards, but the holes still aren't perfect. I don't feel comfortable shooting them through a suppressor. At 100 yards, they are not stable either. Some make round holes, some oblong. They are marginally stable. If I up the charge and get them going 100 fps faster (into supersonic territory) they get better.
The 208's make nice round holes at 10 yards and at 100. They are also fairly accurate.
The 220 Pro-hunters shot the best group of the day at 1.15", but appear to be unstable. This is strange considering they are quite a bit shorter than the 208's.
