Use the 348 gr PB's in my sidelocks with 70-90 gr of Pyro RS depending on the rifle. Works very well, usually bang flops inside of 50 yards. Usually recover the bullet on the far hide, so not so great on the blood trail. I don't think I will buy more when they are gone, though. The price is just too high on them. I am going to try the 350 gr FPB when they are done, since I bought several packs at Walmart clearance prices.
