The last few weekends have been busy, but finally I had some time this weekend to test the Xtreme 200gr SWC bullets.
The accuracy results were not what I expected, but it could have been me since I was fighting failure to feed issues today with the SWC bullets. I did not change anything regarding COL or crimp, but I shot a total of 60 rounds instead of the previous just 5.
It seems I will have to decrease the COL even more to see if it will help. So far for me with the P220, the Berry's 200gr RS bullets have been flawless with no failure to feed, so it seems it is a better fit for my P220.
Even though the SWC groupings were not that great, it compared well with the Berry's RS groupings. The best grouping with BE-86 was 6.3gr for both SWC and RS, and the best grouping with SportPistol was 5.3gr with SWC and 5.6/5.3gr for RS.
Following are are SportPistol results from my testing today:
