240 Grain Sierra in .300 Blackout?

I'm just starting to load for the .300 Blackout and I'm interested in loading heavy subsonic rounds. Seems like most of the data centers around 208-220 grainers, and that is fine with me. But, I see that Sierra has data for their 240 grainers, and right now I can get 500 of them pretty cheap. Has anyone done this? Am I getting into the realm of too much of a good thing? I have enough twist for them so that is no issue.

I didn't jump into the whole .300blk bandwagon. I myself like te 6.8mm cartridges. But I would think as long as you have a good enough twist to stabilize the bullet, and the load data is good. Then go for it. It would be really cruddy to have a baffle strike or something if you were running a suppressor though. If you are, then what cost more money/is harder to get? Different bullets or a new suppressor?
