Anybody loading 6mm ARC with Superformance, Staball 6.5, or N550?

I am fixing to shoot up my remaining 108eldm’s and going to make myself another batch. I habitually re-check all the major manufacturers before I make any decent sized batches of bullets and this time I noticed from (hodgdon’s website) that there are a good number of slower powders. I don’t remember seeing these the last time.

Long story short, Superformance, Staball 6.5, and N550 are powders that I have, like, and (according to the internet) show promise for speed. The bullets I will shoot are Hornady 105 BTHPs and 108 eldm. I currently am shooting Leverevolution and have both of these bullets going ~2600 out of an AR.

Has anybody used any of these slower powders for 100-110gr bullets? If so, what did you think and what were your results? I’m curious about accuracy, speed, and also function from an AR.

I think they’re gonna be to slow. Or at best sup optimal. I use leverevolution,cfe223 and aa2520 for 107smk in my gas gun

Did you ever try out the Superformance? Debating on trying some based on Hodgon's load data. Worried that the powder won't all burn in 14.5" though.

No I haven’t. Have some 105 BTHPs loaded at 31,32, and 33 but haven’t shot them yet

Let me know how they perform. Worked up a precise load with them for my 16.5” 6.5cm but they were very dirty. Worried it will be even worse with an AR.
