457-170 RF

These are just what I was hoping they would be. They shoot super tight groups at 30 yards through my Seneca 909 air rifle.
I've been using the 166 grain slug from Hunter's Supply which is just a bit loose and can fall out of the chamber even when seated. These arsenal bullets are a snug fit and now I can cast them myself.

I use this rifle for groundhogs and this is gonna be the slug I keep in the chamber from now on.

They don't seem to change at all going through a Lee .457 sizing die.

The mold is of high quality. Drops pristine bullets and fit right into a pair of Lee handles.
