This could go on for days but the bottom line a suppressed rifle is the answer here. Get a rifle you like in a 6 to 6.5 chambering and carry on. Forget watered down loads brakes pistol chamberings and all that. The easy button especially if you wish to use factory ammo is a 6.5 creedmoor in a rifle you like with a appropriate suppressor and barrel length. A 16-18” barrel is fine the recoil will be managed and you still have good ballistics should you need them.
