I am reloading my 7mm WSM and I am using Retumbo powder for the first time. Going by the recommended loads from Hodgdon for a 162g bullet (66g to max of 70.5g), and I am using 68g, itfills the case to the shoulder. When I try to place a Hornaday 162g into the filled case, I have to force the bullet into the powder with a crunching sound,leaving no space at all. I have never had a powder do this. Is this powder designedto dothis?I have never had a case filled with no airspace and am concerned about pressures. Anyone else have experience with this?
