They are not a copy of anything, exactly - ballistically, they are a miscellaneous RemChester/Verslite-ish wad and load like one. They are not very 'sticky' and you won't have any surprise pressure spikes.
Both 700-X and Red Dot (Promo) can get a little pressury in 1-1/8oz loads if you're wanting to go 1200+fps.
Assuming you're using AA/STS hulls, how does 19 or 20gn of Green Dot for ±1150 or 1200fps-ish sound? If you're using straight-wall hulls, add another grain.
Straight out of the Down Range catalog. The XL-1 1/8 is equivalent to the Winchester WAA12. If you look at the Alliant site they reference the XL wad in many recipes. Below is a sample of one of the many loads directly from Alliant Guide linked above.
