As most of you know, we are making improvements on all of our SAUM based chamberings. This change will increase case life and have the potential for higher useable velocity.
Here is what you need to know:
You will need to order the new reamers and dies designated (/B) after the chambering (i.e. 7SS/B). New reamers are being cut now and new sizer bodies for the dies should be available Dec 2022 or Jan 2023. In the meantime, the old original dies work great as a shoulder bump set!
Eventually, if you choose, you can add the sizer body for full length sizing but no need to wait to re-chamber. If you wait to buy the NEW 2 die set, you would order the /B dies. If you currently have the old chamber, you can re-chamber with about ½” of barrel setback and still load with your old dies as a shoulder bump set.
Some people have been confused but, BRASS WILL REMAIN EXACTLY THE SAME!
