10.5 barrel & suppressed?

[Variable]

I'm trying to piece together my SHTF rifle and I know what i want, but I don't know if it's viable. I want a 6.5 grendel 10.5 in barrel with an AAC 6.8 suppressor. Does anybody have any experience with this and know if I will run into dwell time / cycling issues. If it is viable, will I be constricted to only using certain ammo loads?

I run an AA 10.5" with an AAC 762SD can on it and it has always run great. Bill Alexander deliberately undergassed the 10.5" guns so that they'd run fine suppressed without getting too beat up. I've had no issues with mine at all that I can recall either in full or semi.

Here is an old pic when it was still newish and mostly clean:
