Sitka Deer;
Good evening to you Art, I trust this finds you and your fine family well tonight.
As you likely know about me, I've never waded into the pucker brush for anything larger than a decent sized interior black bear - so I'm in no way commenting on what might or might not work on coastal grizzly.
I can say however with a great degree of certainty and confidence that many if not most of the guides I know and have talked to absolutely HATE braked rifles.
It puts them in danger of receiving long term, permanent hearing damage - I know of more than one case where this has occurred.
Personally I had enough poor experience with them at the rifle range that I don't really like them much myself, but absolutely do acknowledge there are reasons for using them - arthritis or permanent muscle damage in the shoulder comes to mind.
Anyway if anyone out there does choose to do a guided hunt with a ported rifle, please be extra careful of their hearing and thanks in advance.
All the best to you and yours Art and good luck on your remaining hunts.
Dwayne
