Reload Data for Winchester JHP-Notched 110gr..38 using Alliant Unique

When you say "notched", are you speaking of a bullet with a canelure? If so, that notch, as you refer to it as, that is the spot you crimp the mouth into.
As for data and other specifics of the load, you need to buy a good reloading book. For your safety, I would strongly discourage using data that is provided to you second hand.
Another word of advice, don't reload when you have distractions. One seemingly small mistake can cost you dearly, both economically, and physically.
GS

it does have a cannelure, but the jacket runs fairly high up the ogive, so it is scored to aid/control expansion..

attached pic is a 158gr version

The terms your looking for are SCORED or SERRATED to promote expansion.

I have shot a ton of those 110's, but I wasn't using the powder your looking at. I had them loaded pretty snappy and I used them to remove nuisance raccoons from my deer feeder. They usually didn't exit from my 6" GP-100.

They are a bit touchy when trying to find accuracy so don't be disappointed if you don't hit an accurate load right of the bat. I used them in 4 - 38SPL's and 2-357' and none used the same load, and all but one shot them no tighter than around 4" at 25yds, the one GP however will simply eat out a ragged hole with them, but the load is a smoking one.

As others have suggested it would do you well to invest in a couple of reloading manuals or at the very least head over to the local library and browse a few older copies. The powders like 2400, Unique, AA-5,7, or 9, haven't changed enough in the past few years, that if you start low and work up as you should, you shouldn't hit any snags.
