Does anyone have solubility data of HCl in various solvents (Methanol, Ethanol, Ether)?
I've been searching for the past 20 minutes and to my surprise I can't find any data about this. At best I can find companies selling premixed
solutions of different concentrations, but this doesn't tell me much about solubility itself. I am mostly interested in it's solubility in Methanol.
Any information is appreciated.

Why doesn't it tell you much about the solubility itself? Aldrich sells a 3M solution of HCl in methanol. Are you trying to make the most
concentrated solution possible, is that your question? Because otherwise 3M is a good data point.
They also have a 2M in ether and a 1.25M in EtOH which are again good data points to have.
A quick search though gives the following information:
| Quote: | Solubility in methanol: 54.6 g/100 g solution at -10 deg C; 51.3 g/100 g solution at 0 deg C; 47.0 g/100 g solution at 20 deg C; 43.0 g/100 g solution
at 30 deg C; solubility in ethanol: 45.4 g/100 g solution at 0 deg C; 42.7 g/100 g solution at 10 deg C; 41.0 g/100 g solution at 20 deg C; 38.1 g/100
g solution at 30 deg C; solubility in ether: 37.52 g/100 g solution at -10 deg C; 35.6 g/100 g solution at 0 deg C; 24.9 g/100 g solution at 20 deg C;
19.47 g/100 g solution at 30 deg C

Pretty much. I still plan to titrate after making it the fact to determine what concentration it ends up at, but it would still help me a lot if I had
a rough idea of how much I can expect the methanol to hold. I prefer to have as much data as I can before I go into things like this to avoid wasting
reagents. Something as common as HCl, had me surprised I wasn't able to more easily find a solubility table/chart online.

I found this.

Hopefully, this will help you.
Edit: I could not easily find the data for HCL, but it appears to be here.

This is given on p. 50 of "Purification of Laboratory Chemicals" by Armarego and Perrin (6th Ed.):

I looked over the data from multiple of the above posts (thank you everyone), and if I am interpreting them correctly, Hydrogen Chloride can dissolve
into Methanol at up to a 45-50% concentration? Isn't it's water solubility capped around 37% or so before it starts fuming? I didn't imagine Methanol
would be able to achieve such a high concentration.

100g of methanol has a larger volume than 100g of water due to differences in density. Essentially you're dissolving the same mass of gas (HCl) in a
larger volume of solvent, hence the larger %w/w concentration.
If you normalise for density of the solvent then both water and methanol both give HCl solutions around 37%w/v
