Recently picked up some 158 grain Cast SWC .357 bullets to load for my Dan Wesson 15-2 .357 mag.
I have plenty of Bullseye on hand. Lee Modern Reloading says that for the 158 grain lead bullets, use between 5.9 - 6.5 grains of Bullseye. I thought I would start at the low end and see how it does.
Problem is, I keep reading that many people use between 3 - 4.5 grains with Bullseye and 158 SWC bullets.
Are these for light loads or is the Lee manual too stout?

Check Alliant Powders website. Bullseye is a fast burning powder that still is pretty versatile. I like using in all the ranges you mention. Great for target loads in the 3-4 grain range, and without pulling out the manual, you can push 1,000+ fps in the high 5's if I remember correctly. I do think that my manual shows max at 5.9 or so, better off pulling good info from the manufacturer's load data listings than anything else. Have fun, be safe.

Although I've not loaded with Bullseye, most reloaders use it for light target loads, hence the smaller charges. I would use Alliant's most recent data as a starting point and work up from there.
If you are wanting something with a little more oomph with the 158grn SWC's (which is what I load as well, in both .38 and .357 loads) maybe try something a little slower... like Unique.
It's funny how data from different books, and even different editions of the same book, differ...
3.5gr of bullseye is the old standard for 38spl bullseye matches.. If you are new to reloading or using bullseye i would suggest you stay away from it. BE has destroyed more firearms than the communist have.
Let me throw some numbers out there to you(all 38spl numbers). 3.5grs is safe for all 38spls and opperates at very mild pressures. Lets say you boo boo and the bullet sets back from recoil and compresses the powder slightly, those mild pressures just spike up to +p to mild 357mag pressures.. Now lets say you throw a double charge... your now in the rifle pressure range.. now lets say the powder is now compressed and double charged.. your at the 60-70,000psi range. more than likely you want have any fingers or a hand at that point. To me you need a far slower powder in a magnum.. H110,W296,H4227,N350 and N110 all give great fill out to avoid doubles and really lets you get "magnum" speeds
