At the shop where I bought the XTP's today the owner had some .451 Speer bullets that came in a plastic yellow box of 100 that looks exactly like the box TC round balls come in. It didn't say Deep Curl or Gold Dot or anything but Speer on the box. The bullets looked similar to the XTP. Does anyone know what kind of Speer bullets they are? He said they don't sell so I might be able to get them at a reduced price.
