i have known several disintergrate while being used on a centre fire rifle , they seem more trouble than what they are worth and you still have the sonic boom anyway ,no doubt someone will have a different oppinion ,for stalking you only usually get one shot so i do not bother about the noise factor .
i think they are a pile of shite on a big rifle
hmm similar to what i was thinking, i think they come into use with 22rim fires for lamping etc because of noise reduction but as you say wilst stalking it is only one shot.. the only other benifit i can think of would be a slight decrease i
