Hi again,
According to the barnes manual, IMR starting loads for 4064 is 43.5 @2491 fps MAX is 47.5 @ 2720
IMR 4320 starting is 44.0 @2421 MAX is 48.0 @ 2641 fps.
If you wish to use an H powder try H4350 starting at 50.5 @2532 and MAX @ 54.5 @2733 fps.
Remember, these are book listings, I would start even lower. For your 22" tube probably the IMR powders would do best. For less temprature sensitive powders, try the H powders.
Also 200 primer will do fine. If hunting in extreme cold, maybe give the 250's a try.
Good luck
