Thread: Using a suppressor with a larger diameter than the rifle caliber

I use a Gunworks 30 cal over barrel Suppressor on my Model 2 Brno, and it's super quiet. Your 7mmRM one will be 0.75mm wider all around, but will be multiple times greater volume than a .22.. What thread is the 7mmRM? Your main concerns are that if you have the .22 threaded in the same thread as your RM, is the .22 barrel profile appropriate for that thread: ie enough shoulder to seat the suppressor up against? And, if you ever decide to sell the .22, with a weird-for-rimfire-thread, will it make it harder to sell? (If you aren't planning to sell, who cares)
