2 pellets at once?

[Airgun-hobbyist]

I've done this a couple of times on accident its fine until the bind up in the barrel at some point making a nice lead wedgethat's never happened to me but I worry about it

You definitely do not want to do this double shot with a bigger bore slug gun that can potentially lodge a slug. With a slug lodged in the barrel, the next shot will not be good on the barrel when it slams into that lodged projectile, at the very least. Moreso, with airguns like the first gen Impact and it's not so secure probe, it could be even worse because the probe screw is a weak link that has been known to allow a probe to be blown out backwards.
