All major ammunition manufacturers use primer sealant and if you want
the power and reliability of factory loads, you should too, especially if you
hunt or shoot in wet weather. Each 1/2 oz. bottle seals up to 1000 primers,
making them watertight so moisture doesn't hinder performance.
This stuff applies easily and seals out any possibility of moisture impacting your ammo. The sealant is very inexpensive insurance for today's ammo which is insanely expensive.
I treated bullet and primer , put them in a plastic garbage can under a foot of water for eleven days. All shells fired great ! Been useing George and Roy's for something like twenty year's. But I put it on AFTER reloading, not like the NEW directions say during primeing.I Put it on wipe off.
