Out of the 3 , I’ve burned many pounds of RL17. I have nothing but great results with it.
My understanding RL16 is a direct replacement for H4350 being temp stable plus a decoppering agent.
If I had to guess RL15.5 is Alliant’s form of Varget temp stable plus decoppering agent.

Speeds are much better from 17 than 16 in my experience. 16 has been a disappointment.
Trying 17 in my 338-06 again tomorrow.

My 416 Bee loves RL-17 and the 330 GS Custom HV. 3150 fps. I was hoping RL16 would be more temperature stable. Of course this is a moot point, either is unobtainium.

Main difference is that I can sometimes find 15 on the shelf.

I'd swap you my RL-16 for almost anything else in a second.
Of course, won't be out your way for 2 more months so you'd have to wait a bit for it.
I have used a bunch of 15, some of 16 and a really decent amount of RL17.
16 seems like it does what H4350 does but with a skosh of extra speed along with the temp stability of 4350.
17 has been excellent in just about everything though, fast and usually very accurate. It replaced RL19 as my favorite in my 338 Win a few years back.
