I had never heard of this. I don't really see anything online about it. I can only assume it has been discontinued as well?
An SR4759 equivalent would be nice.

That add is confusing to me.
>The jug label says "SR4759"
>>The title of the Ad says, "IMR8188 rifle reloading powder 4759 like unique"
>>>The description of the Ad says, "1 pound of surplus IMR 8188 powder, this is a faster rifle powder excellent for cast lead bullets. Burn rate is similar to SR 4759."
.
So, one of my goto burn rate charts lists 153 powders.

That put's Unique at #34
and SR4759 at #69

Below is the link to the super comprehensive chart I used, that numbers to 532. It has Unique at 136 and SR 4759 at 277. SR 4759 and Unique are nowhere close to each other. Very suspicious listing, powder, and seller.

At the casting bench in the sky. RIP Bret.
As has been pointed out here recently, the problem with burn rate charts is that each spacing isn't a given amount faster/slower. IOW Powder #27 might be 3% slower than #26 but powder #28 might be 20% slower than #27. I'm not sure how you'd fix that in a way that would give the average Joe a meaningful idea of what equals what.
