Well buddy I use a cva magnum hunter and a friend if mine uses a knight and we have both tried just about every bullet there is out there and we both like the thompson center mag express sabut he uses 240 gr i use 180 gr they are the most accuret rounds we have found I droped a doe sunday morning and the exit was about the size of a golfball from about 150 yards or so I use 100 gr of powder not sure but i think he uses 150 gr i have never had a problem with 100 it works well for me just remember when u load up pack it down real good I throw my ram rod down the barrel tell it bonces back out. The 240 gr are easy to find the 180 you have to order from bass pro or cabelas i havent been able to find them anywere else.

I have an Encore and shoot a 260gr. Harvester funnel point in a crush sabot in front of 100grs. of Blackhorn 209, very accurate.
