brasstacks;
Well you've most definitely been given a variety of opinions on this subject, which if past history is any indication, was to be expected.
My standard warning on any muzzle braked and/or ported hunting rifles is to please make sure all the folks in the hunting party are aware of the potential for hearing damage.
A good friend from the Yukon used to guide a bit in northern BC - back in the day when brakes were just becoming a fashionable accessory. Anyway, a chap from Alabama touched off a braked .340 Weatherby when my friend was, as I recall, about 10-12' to one side. He related it was like being hit on the side of the head with a 2"x6".
He also said his ear "rang" for several days after, indicating to me the good possibility of permanent hearing loss.
As another thought as well, after teaching a couple of horses to not be gun shy when shooting, I'm not certain that I'd be shooting a brake equipped rifle too close to a horse.
For those who've not hunted solo using a hay burner, my circumstance sometimes dictated shooting whilst kneeling on the 15' lead rope. While I generally tried to tie them off further away from the shooting, it wasn't always possible and with a non-braked rifle they were OK with me being 15' away as long as they knew the noise was coming.
If one was hunting with a guide on a horseback mountain hunt and one intended to use a braked rifle, I'd think perhaps it would be wise to discuss that detail up front and eliminate "unpleasant exchanges and situations" after the fact.
Shooting prone has been discussed already and while it's not legal to do so here, some jurisdictions allow one to rest over the hood of a hunting rig to shoot. I'd suspect that a braked rifle may rearrange the paint scheme on the hood more than desirable?
Thanks for the interesting opinions and information all, it's been an interesting read.
Regards,
Dwayne
