Have you ever gotten the impression that nobody gives a shit when you say something? They just ignore you! Happens to me all the time.
Try the slugs! I did and they worked just fine. Keep an eye on the diameter or they might not feed/exit the barrel fully! Other than that, they fly better than pellets. If the Veteran’s fps is as hot as the .25 is, you will have no problem at all. They are expensive. An alternative might be the heaviest .22 pellets from JSB or H&N.
I would have answered much earlier…but to be absolutely honest with you…I didn’t really give a shit.
