There is “hearing safe” that makes some guys ears ring. There is good suppression. There is great suppression. Then there is the best suppression.
Usually best costs more money. I didn’t pay anywhere near $2300 for my 338 Ultras. But I would in a heartbeat after using them.
I’ll pay $2300 for a max suppression can before I pay $1k for a suppressor that makes my ears ring.
OP wants max suppression under $1500 for a 6.5 Creed. He didn’t say good. He said max. The 338 Ultra is the best that fits his criteria.
Can you answer his question? What suppressor will give him max suppression for a 6.5 Creed, under $1500?
