I used the 1680 in a 357max. As near as I can tell, 1680 is pretty much the same as ww680. This might be a good place to get an idea.JUST got a very old ~lb of it... What else is it known for?

it'll run your 375 win. cast loads clear up to too fast if you chose that route too.
Take a look in the Marlin Owners Group Forum. Under the thread 25-20 reloaders. Last time I took a serious look they were up to 85 pages! I went to that thread typed in the Search Community box the term WW680 and many responses showed up. Happy browsing.Well years ago I used WW680 in my 218 Bee Winchester 43, I’m talking 40 years ago.
But I remember it working nicely.
But, all of my early load data seems to be in parts unknown.
I’m now totally interested in using cast in mid range loadings. With jacketed bullets I have information in early Hornady manuals and others.
I’m currently working with Red Dot and have a few other powders that will work, but I have 7 or 8 pounds of WW680 that I’d like to use. I guess my main question with this Ball powder is can it be downloaded safely.
Interest is in the Hornet, BEE, and the 25-20.
I remember this thread and hoping revitalizing some interest in it.
7.62x39 and I think it has been used in .30 Carbine.JUST got a very old ~lb of it... What else is it known for?
Well good information. I guess I have heard that about SP primers compared to SR primers. I’ve believe I’ve heard that about the Hornet and the BEE as well.I shoot the same 12.5 grains with the 35 grain Vmax in both the .22 Hornet and my .218 Bee . I still have 10 pounds of 680 but I have also used 1680 and it works the exact same. Also Lil Gun shoots exactly the same . I use small pistol primers only , tried all of the small rifles and none gave the same kind of accuracy. Have never tried cast but I'm considering it.
