I've been shooting the jsb ko's in 13.43 in my RTI Prophet Performance for a couple of months now and the thing is deadly with them. Accurate, hard hitting ( sometimes hilariously loud "thwack" when it hits starlings and/or pigeons ) - I've no complaints with them. They're going about 980-985'ish fps. I'm down to a couple of tins left . . . I either need to re-stock *OR* . . . . try something a little heavier / beefier like the nsa 15's??? (( or do I? ))
Those of you shooting .177 slugs - opinions on the nsa 15's ( or some other brand that is heavier than the ko's? ) - OR - just stick to what I know works and leave it be? The wind does still move them around some ... yeah I know - .177 - small & light - what do you expect? ;-) Thus - sort of toying with possibly playing with something a little heavier.
