I am pretty sure that the WSM and WSSM both can use the .532 bolt face. I have a BAT with a number of tubes, including a 6.5 WSSM and a 300 wby. Both work just fine.ab_bentley said:Also the WSSM bolt face, Wildcats/ Calibers are as numerous as the sands, If you had a complete list, wow that would be a volume. PTG offers a book with all standard and wildcat reamers they have produced, I think it's 43$ from Midwayusa. Adam
