not reloads.
sticky bolt is due to difference betweeen 7.62x51 and .308 win.
.308 win is actually hotter, higher pressure, and it extracts fine.
I'm having some stickiness using a few different types of 7.62. CBC Magtech has brass thickness issues and my chamber REALLY holds onto that crap, to the point where i need to smack the bolt handle up. ZQI generally unseats fine on the up stroke of the bolt handle, but requires a strong tug reardward. Was shooting some south african the other day and while it wasnt bad, it was still sometimes hard to unseat and sometimes sticky on the rearward stroke. then fired some federal .308 and it was noticably hotter/louder and it all extracted like butter.
