[QUOTE="Mram10us, post: 1820840, member: 111667"] Took out the ultra X for the final time today. Here are the final findings: 1. It seems the flat in the chamber from the beginning of the chamber forward .700”ish is too much. It makes chambering tighter than it should be 2. After firing 5 times for each case, the case needed to be sized to the base. The 300wsm FL die wasnt Long enough 3. The growth on the sides of case was too much for Rem brass, but Norma and Bertram did well. 4. Accuracy was great. Very happy there 5. Learned a bunch about alternative fireforming methods, so that a plus Next tests will be on chambering with cases that have less case growth on sides and less flat near the base [/QUOTE]
