I can't help you much with a Pursuit Arkieduckman. Never owned one, but came mighty close when I bought my Mustang. I sure did like the feel of the Pursuit I was looking at.

Anyway, I think I would start well below 120 grains of Triple Seven. That load is going to really WHOMP you under a 295 grain bullet. Were it me, I would start with 90 grains at 50 or 75 yards. Shoot a threeor five shot group, them move up to 95 grains and shoot another group, then to 100 grains, etc. etc.
