I am with Will, if you short stroke a bolt action rifle then you probably can't chew gum and walk at the same time...

I don't accept that short stroke therory at all...You pull the bolt back until it hits metal and won't come any further, to stop it in midstream is ludicrus if not seemingly impossibe IMO...Not saying who is right or wrong in this issue, just putting my perspective in the thread...

Mudbug,
I know Harry Selby and his son Mark very well.. Harry only used the 458 for a very short period at a time when nothing else was available to him and he couldn't get ammo for his 450-400-3" and he didn't have the money for a 416 Rigby..He correted that situation shortly thereafter when he came into some chips in the form of tips...That is from the horses mouth...He didn't care for the 458 or the push feed M-70...
