Can't see getting a squib but I can see getting an over pressure round if the crimps too tight. Think I'll buy a case and give this a shot.....carefully. Anyone know the best dies to get for the 5.7 that allows for this type of precision loading?
From reading the reloading threads of the 5.7x28mm rounds, and also from talking face to face to someone who used to reload 5.7x28 brass, the risk of overpressure is high especially since just as little as a 10th of a grain too much powder could cause an overload. The guy who talked to me about the 5.7 he reloaded no longer does it. He siad it was too much of a pain in the @$$ to do so he sold off all his 5.7 dies.
As for crimping plus glue causing an over pressure, I don't know if that would be the straw that breaks the camel's back, but considering that the 5.7 round is already touchy as far as getting the powder weight right, crimp plus glue might cause a problem if the crimp is done wrong.
I don't know because I haven't attempted to reload my 5.7 brass yet. I still need to get the correct dies and all.
I've reloaded other necked sheels; .30-30, .30-06, .308 Win, and I haven't had problems from the few crimps I did which I thought were questionable.
But according to what was told to me, the 5.7 reloading process is not as forgiving as reloading these other center-fire shells.
