GM54-120
I used 100gr BH209 and the Havester Smooth until i got them resized to .401. Now i use the MMP tan but i need to adjust the powder and primer combo again.
I never even tried an MMP - probably should have... I kninda thought I might be stressing the Harvest Crush with the BH, that is pretty heavy bullet for such a heavy bullet and decent force pushing it. Harvester never designed it for that weight. 200 grains was probably the upper end.
do a bit better in my Acurra with the slightly faster twist than in the Elite.
The fster twist certainly could not hurt but the length/weight should do just fine in 1/30 according tho the Greenhill. As I mentioned the lube could have been a part of it and then when i am shooting through a chrono I am more concerned about the chrono than the target.... so that takes a little concentration of the target....
Running it through the calculator, its still good for over 1100fpe at 200 yards and 14" low with a 50yard site in.
What are you using for a BC on that bullet? Can not imagine it is to high.... + the BC you have might have been calculated for the velocity expected from 40 cal black powder pistol. Changing the velocity will change the BC also.
It was fun to shoot them... I should haveshot some @ at the 100 yard birds just for drill.
they are supposed to have a hardness of about 15-18 BHN.
I really have no clue about the hardness... would they work in a thin skinned deer or would they just push on through??? It seems to me they are harder than my Bull Shop conicals...
