Know another guy who picked up a custom rifle with a very
light trigger in 270 Win. Next day at the range after he
had sighted it in, he was trying his luck offhand at 100 yards
as he was chambering a round and bringing it up his shoulder
it went off and gravel flew everywhere about 15 feet in front
of us. It just about jumped out of his hands from the recoil
and he jammed his finger bad. Later on after he cooled off
and did several function checks, the gun was not the issue and
he admitted to having his finger on the trigger while bringing
the rifle up.
