I'm not here trying to start an argument, just relaying information.

I shot probably 3-400 rounds of the Super through my 625 before calling Sierra. I was not calling for loading info, I was asking if the bullet was suitable for the velocity I was loading to. I liked the gun so I quit.

My friend said he ruined his, I never saw it. I was doing this way before my internet days but I have seen conflicting reports about this through the years, I do not know the answer.

Al I know is my 625 still knocks down pins and I still shoot my V16 with Supers but I went to a heavier spring than Springfield recommends and hate putting it back together. Cheers.
