If your shooting them thru a suppressor, the suppressor needs to be cleanable - and you have to make sure the gas check stays on the shank.

and of course if using an AR, you want the gas blocked or you tube will fill with lead and lube. on a T/C or bolt gun not a problem.
202 grain 311299 looks to be a good choice. I'm in a group buy for 165 ranch dog which has big flat nose that should be a stunner for close range work.
