I had CEB make a 350 Raptor in .510, primarily for the 510 Alaskans I have, but this bullet you can also use in that 510 Wells too, seated deep and using a Talon Tip, it is a wicked Bullet, and I suggest strongly you try some if you ever
decide to hunt that rifle for bigger critters, moose/bear and such...........
But otherwise you can get by with the cast. I don't care much for cast bullets, but fine for shooting and playing around, and for deer/pigs and such.............
