I have one of the older "overbored" ones. it shoots Hornady LE's all day just fine. Thanks to Tim, Quidkdtoo, it's now a .445 Super Mag and it shoots all just fine....44 Special, .44 Russian, .44 Mag and .445. They are an excellent 100 yard deer rifle, and with the right shooter are good for more than that.
Do it, you'll like it.
