I don't remember the last time I didn't see the bullet strike with any of my rifles, up to and including the 30-06, unmoderated.
I don't recall any of my neighbours or landowners complaining about the noise of me using an unmoderated rifle, ever. Yes I could 'assume' they would be bothered, but I could also 'assume' they won't be!...
I'm reasonably fit, in my thirties, run 4 times a week, run a 3:30hr marathon a couple of times a year, do mountaineering, etc,,,yet, I find the unbalance and weight of moderators and harris style bipods an incovenience, call me crazy. yes, harris bipods 'do' dig into the shoulder, at leaste every one I've ever owned has.
anti-slip slings - I like my leather slings thank you...mind, the problem is not the sling slipping, it is the butt of the gun flying under your arm the second you stop supporting it due to the top heaviness.
muzzle flash - are you kidding me, you really saying you've ever noticed or been bothered by this? are you afraid of the deer counter-sniping you?
people getting bothered on the range - F-them, who cares, if you can go to the range and shoot comfortably in every other country in the world without moderators, surely you can here too.
hearing - yes, but seriously, stick in an earplug now and again. do you know how many people go on driven shoots and blast away all day long without any hearing protection, yet refuse to leave the house and sit and shiver in the shower with fear at the thought of firing a .22 without a moderator...
moderators to help concealment - see above on counter-sniping...LOL
multiple shots on quarry - am I living on a different planet? I don't ever recall not seeing the bullet strike, nor having problems with multiple shots on quarry. If I've picked my targets before I take the first shot I can usually move onto the 2nd shot pretty swiftly and without hesitation.
...hhmmm, not convinced...I still think it's a money maker that the police happen to think is good for H&S and people thinking it's a 'must'..however, please don't tell me you smoke/drink AND use a moderator, like a vegetarian wearing leather belts...LOL..
