No rifle is 100% reliable, but the goal is to get as close to 100% as possible.
BTW - The PH's of this world (which includes
@IvW) are considered an excellent source of information.
From real world field experience alone, not time spent on a rifle range.
Their lives, and the lives of the ones around them depend on the reliability of their rifles.
It is for that reason that an overwhelming majority choose a true CRF Mauser style rifle.
I'm not saying other rifles aren't reliable...just that the ones chosen by PH's have a proven track record.
You can take note or disregard because the need of a PH are very different than the needs of a client.
