Received my BE-86 from Recobs on Friday. Loaded some 45acp's on Sunday morning. Hit the range that afternoon. Just as everyone else has found, the lower throws work great. I shot both 200gr lswc and 230gr rn lead and found both accurate at 10% or less than listed max. I really liked 5.4 gr under the 230 gr lrn. I started at 5.4 and went up to 6.0 in 0.2 increments. The 6.0 was just too hot for me personally to shoot a couple of hundred of in one day. I was shooting out of a XDS-45. The recoil of the 5.4gr was mild, ejection was good and accuracy was good. I'm still working on a load under the 200gr lswc. It will be less than 10% of the max recommended by Alliant. I'll also be trying it in 9mm, 38sps and 357. The 38 looks promising, but (with head held low) I do like the "magnum" feel when that 6" GP-100 goes bang. I am impressed this powder works well in lighter loads without issues like others. So far y'all's results in the 9mm are impressive, so I would expect no less.
Has anyone tried it with magnum primers? I know some powders get erratic with these and accuracy stinks. If no one has tried, I will give it a whirl and let y'all know.
