Best pellets/slugs in polygon barrels

Which pellets and slugs work best in their polygon barrels?

both .22 and .25

i usually try sticking with jsb, even though there seems to be a shortage of them right now 

in .22 there’s jsb .216 and .217 knock out slugs, monster redesigned and beast pellets

in .25 there’s jsb kings and mk2 heavy, and knock out slugs 

I’m trying to buy the ones which are most likely going to be good in my raw .22 and .25
