This is sounding more and more like a worthwhile proposition. 1530 fps is more than what I would ask for (but I wouldn't complain about) although for 200 yds it can only help.
Then there is the possibility of shooting heavier boolits if one had a faster twist rifle which I just so happen to have. Three of them actually. Those being TOZ-17's. Well, two TOZ 17's and a TOZ 17-1. These have 14 inch twist.
