It is impossible to load a ML without covering some part of your body with the muzzle, can't be done. Blowing? its been done untold millions of times and I have heard of one accident caused by the guy loading for his wife and not paying attention to what was going on when she had a misfire and did not keep the rifle pointed down range long enough. NO RANGE SAFETY OFFICER apparentlu either or not enough. Probably no safety briefing before the match either....
Safety? Where is it?
American ML shooters are notoriously cheap. They will pay 250 for a barrel made of cheap materials by someone with a 9th grade shop class mentality (and workmanship) but will refuse to buy a barrel for 400 that is made of certified steel by someone who makes world class barrels that are carefully rifled, lapped and TEST FIRED. Trust me I KNOW this is true.
People are statistically more likely to be injured shooting the substandard barrels that are far too common in MLs in America (in American "custom" barrels are virtually all made of a steel the steel makers specifically say is unsuitable, documented way back in the 1980s and there are failures and INJURIES some life changing, but the average "expert" thinks its from loading improperly because "barrels don't blow up with BP" a myth that has maimed people over the years). Then we have the "re-enactor grade" guns, the unbelievable crap coming in from India, two failures I know of with BLANKS. Then we have the improperly assembled percussion and flint guns that puke out nipples and the drums break off, flint guns made by people who should know better (and do but don't care) with vent liners that blow out perhaps only held in by the lock plate, cause the fool that made it does not do things in a workman like manner (don't care) and will not even proof the barrel.
But people will gleefully shoot this cheap crap but then tell me that blowing down an empty barrel is unsafe. There is no choice if its the rule for the match so one makes do. But there are far more dangerous things done every day, shooting the pipe bombs for example, than blowing down an empty barrel which is about as dangerous as a kid blowing bubbles in chocolate milk with a straw. In general its safer to shoot an Italian reproduction than a $5000 American custom with a barrel made of leaded screw stock. The Italians at least use better grades of steel.
So tell me again about "safety" when a lot of people here put a cheap piece of steel that is mill run, not certified in anyway, not recommended for gun barrels or any other "pressure" vessel use being designed to make cheap screws in an automatic screw machine, right next to their face then shock load it to 10000-20000 psi. The steel generally used is also SHOCK SENSITIVE BTW (one of many reasons its unsuitable for barrels).
Most ADs I have read of come frome heavy fouling accumulation in the breech area, poor quality locks, thinking a percussion is "unloaded" after the cap it removed or doing rapid fire re-enactments and dumping powder on a hot ember in the excess fouling produced by shooting blanks.
Yeah blowing down the barrel is dangerous...
