Dont take it the wrong way...When you get complaining it could also be one of two things: They are genuinely bothered by the loud noise (in which case it s their fault they got cheap ear muffs....) Or they are Jealous and possibly being sarcastic / ironic which is a kiwi way of saying I like what you have but I wont admit it....Some of these subtleties can be lost on those who have learnt english / kiwi as a second language.
I am also a member of NZHA and a 338 is currently allowed unless the rules have changed since I was on the committee. I have personally used a 375 H&H magnum out there and there was no issues there either. PM me if you have any issues and I can pass it on to those who are in charge or talk to those in charge on a Tuesday night.
Oh, and with the 338 it could well be worth asking about the 200 yard range and qualifying for that when you are out there....
Welcome.
