Need 45-70 loads Lyman 457191

[sse]

I am running out of 5744 and want to load Unique (for my Win. 1885 Hi-wall made in 1917) with the 292 gr. lyman.
I am not finding much info for that combo. and I don't want to hurt the old girl but I don't want to just shoot mouse farts either.
Any info would be appreciated.

With Unique under a 319 gr cast I've used 10 gr as a start load and worked up to 15 gr in my TDs.

Thanks Larry.
I worked my way up to 16 gr and that gave me 1400 fps with no signs but without any more data I guess I will stop there.
