BE-86 and 38 spl
The data on BE-86 shows 4.6 gr behind a 158 gr SWC as max. Recon it would be OK to try 3.5 gr behind a 148 HBWC? I'm trying to come up with another load and was wondering about this. I have 8lbs of it so I should be set for a while.
Thanks!

BE 86 is supposedly in between unique and power pistol,,, if it closer to power pistol you should be ok. However Hornady,,, ( only manual I have handy) lists 3.5 as a max load of unique.
What is the length of the 148 vs the 158 ? As in once seated do the two bullets basically take up the same amount of room in the case ?
If 4.6 is safe with a 158 AND you are seating the 148 so same amount of bullet is in the case, I dont see why it wouldnt be ok.
Dont think it would be that accurate till u got the pressure up though.

What is the difference between BE-86 and Bullseye? I have read various accounts that it is BE with flash retardant, BE made by different process, and a totally different powder.
Bullseye is a favorite. I have likely rolled tens of thousands of 2.8 grain Bullseye under a LHBWC, supreme accuracy. 3.2 under a LDEWC chronys higher, is accurate, but not as accurate as the 2.8 load. For faster bullets I use Unique.

BE 86 is NOTHING like Bullseye. Its slower than unique.
You are confusing it with Sport Pistol from alliant. WHich is about the same rate as bullseye, but cleaner and flash suppressed.

Like Power Pistol, BE-86 is a derivative of Bullseye. It's not the same, but based on the Bullseye formula. However, using comparative loads in either Unique or Power Pistol as a baseline is a mistake. BE-86 has been described as Power Pistol with a flash suppressant, that's an oversimplification. It's been used for quite a while in commercial ammunition, such as Federals .45acp match loadings. For comparison, BE-84 is Alliant's internal designation for Power Pistol, also a Bullseye derivative. During the big powder shortage of a few years back, Alliant released BE-86 onto the market to help satisfy demand. I guess they didn't feel the need to give it some kind of catchy name. The most accurate 9mm load I've found to date is 5.9 grains of BE-86 under an 124 grain fmj bullet. I also like it in .45acp. A HBWC is a swagged bullet, not cast, so it shouldn't be driven as fast as a cast SWC. You should contact Alliant for their recommendation.

I loaded 10 with 3.5 of BE-86 and got an average of 740 fps. The only thing that concerns me is that I'm seeing a minute amount of unburned/partially burned powder. Should I worry about this?

That 4.6 gr of BE-86, under a 158 SWC load is about the same as 4.7 gr of Unique with the same bullet. I found BE-86 available during the shortage and liked it.

I noticed that for me BE86 performed better and burned cleaner with more pressure. It was not happy with lighter slower loads. A faster powder will work better for this task.

Yeah, I usually do the ol' 2.8 of Bullseye but I'm almost out of it. I have about 8 lbs of the BE-86 and was hopeing it would work.

That load of yours in my 686 6" with a 148gr HBWC did 826fps.
It was also pretty accurate but there were two other powders that
shot a tighter group but it is still a good plinking load, since you
have eight pounds of it to burn up.

When you look for a jack of all trades you end up with a master of none.
(say the fortune cookie)
I'd buy another # of bullseye and get 2,500 quality pulls of the trigger.
