I have not noticed any effect on pressure of loads. I wouldn't expect to as it is way less gas restrictive than the barrel. My primary centerfire suppressor is a .30 caliber can that I use on .243, .260 and .30 caliber. The exit hole is about .325 if I remember correctly.

At long range competitions that I go to, I'd guess that 70% use suppressors.

I met a French guy the other day. I asked him "Do you speak German?" He said "No." I said "You're welcome!"
