Eastern Europe... We had a case recently when a client in eastern European country had no chance to test and zero the rental rifle.he clients were from Eastern Europe and not the best with gun safety from what he told me.
I made few comments afterwards in that thread that in my country is not common to test the rifle before the hunt (also east europe), so most probably in some countries, this problem is existing, hunters not been sufficiently skilled.
I cannot speak for all countries in general, but I am mentioning as a serious possibility. This issue exists here and there for certain.
Eastern European countries do not have gun culture comparable to united states, and many citizens dont have option to train or test rifles periodically, some time no access to the range in vicinity.
Western European countries neither have similar gun culture comparable to US, but generally speaking, with Austrians, Germans, Norwegians, Swedes etc .. that I have seen hunting as a visiting guests in my area, there is no issue. With their system of certification of hunters, tradition etc... they have achieved high level of safety.
Checz citizens, are very special positive case in eastern europe. Very much technically oriented, having numerous gun ranges, and they implemented in their constitution an article, that comes as close to 2/a as can be within EU legislative, for the right to self defense, and easy issuing of ccw.
Czechs are usually well trained.
At my place on municipal gun range, I rarely see hunters training or zeroing the rifle. The gun culture and safety is mostly kept and grown within sport shooting (non hunting) community, and it is engraved in the genes of IPSC shooters. As I belong to both communities of hunters and sport shooters, I can see the difference between the two groups.
Also, as I have written elsewhere on the forum we have statistically zero gun accidents in sport shooting community, and number of accident per year, in hunting community. Another indication.
