Can I pack 4 metal resuable bottles full of alcohol on a checked bag?

I’m planning to bring some alcohol to my destination, and since I’m already taking 4 Hydroflasks with me, I thought it would be a good idea to fill them with liquor to save space, rather than packing an entire extra glass bottle. My concern is that having 4 metal bottles filled with liquid might raise a red flag with TSA, and possibly get the alcohol poured out or, worse, the bottles being confiscated.

Has anyone tried something like this before? I’m also planning to pack about 4 shooters in their original, unopened bottles in the same checked bag. Any advice or experiences would be really helpful!
