Alliant data list a 190 grain jhp with BE 86 at almost 1200fps.
Hodgdon longshot list similar data with really high pressures.
I've tried longshot and accuracy is terrible.
My be 86 load gives phenomenal accuracy. I'm actually surprised when I walk to a 33yd target (That's our pistol range distance) and see 5 shots right at an 1.5 inches.
So I guess that's why I want to stick with the BE.
Just can't find published data or real world experience with 200 grain hard cast.
I'm not looking for set your pants on fire velocity but am thinking a 200 grain bullet in the 1,100 to 1,200 fps is real world 10mm velocities.
First of all, Alliant does not list pressure. Hodgdon does.10mm MAP is 37.5Kpsi - Hodgdon stops at 35Kpsi for a 5" barrel.
Not sure why you can't get an accurate load with Longshot. But the reason you can't find 200gr data with BE-86 is that BE-86 is too fast for that application.
1st of all I didn't say Alliant listed pressures. You are correct they don't.
But my question is if it's to fast for that application why do they list a 190 grain bullet with a load.
Alliant is not a treasure drove of load data like hodgdon.
So it's crossed my mind the one load they chose to list for the heaviest bullet they listed for a 10mm is be 86
