I'm not a big fan of how "cupped", or rounded, these are on the bottom, compared to other makes, but I can live with that.
It says they are to fit "very tightly on a .468 shank' and they were not kidding! They are too tight to my liking. with the ones I received freely accepting only a .464 gage pin. The .004 press caused more shaving than I like on the shank, and certainly needed more pressure to seat them. I ended up making a die to expand or "flare" them out to easily accept the bullet shank, and now they work just fine. This was not a big hassle for me, but others might not have the luxury of doing this.
That being said, they are a nice heavy gas check, and I will continue to use them.
All prices are in USD.
