Bob RNeed help with 220 swift load
My google-foo seems to be very weak on this subject. I have been looking for some 220 Swift loads.
I am loading Sierra 55 grain Game Kings.
My problem is finding data for the powders I have.
I presently have Varget, which I use for my 22-250. I also have Ramshot Hunter and TAC which I can't find any data on. Finally, I have the old standby for many calibers H380.
If some one could look up the data for the Sierra bullets and post it for me, I would be very grateful.

vapodog42.5 grains max of H-380 should get you about 3,800 FPS using 55 grain bullets
