[QUOTE="YZ-80, post: 1800511, member: 109229"] Well, cohunt is right on the 85 dBA deal. The ACGIH used to list the OSHA PEL for chlorine at 1.0 ppm, but the average odor threshold is 3.0 ppm, so by the time you smell the stuff at the community pool, you're overexposed from an occupational standpoint. From what I've seen, it's the least of anyone's worries at a public pool, anyway (think Caddyshack). Unless the DNR is going to come out in the field with noise meters, I don't think we need to worry about it unless we run a guide service and employ more that 10 people. Anyway, I don't think a 6.5 PRC needs a break @ 17.5 ft/lbs. recoil on the average. It's still less than a 30-06 w/ a 150 grain bullet, which is kinda where I draw the line. I routinely hunt with "un-braked" rifles without hearing protection and would like to keep it that way. So my vote is for no brake and a 6.5 PRC and I may just get one. I'll have time to mitigate the temporary threshold shift in the off season. Cheers [/QUOTE]
