I’ve been back and forth between a Sierra 5 and a Polonium K. Price is negligible between the two with keymo. For use on a dedicated 13.7 p&w with A5H2. Weight advantage to Sierra 5 but not drastic. As a dedicated can I will tune my gun as necessary so gas blowback isn’t a huge concern. I know there were some early reports of weld failure on the Sierras but according to Deadair it was limited to ~10 samples and the rest have been good to go. My LGS has a Sierra 5 keymo in stock so small advantage that I could shoot at their range while in jail, vs Polonium would be via Capitol Armory.
Thoughts? Anyone here been able to shoot a Sierra 5? Bonus points if you have familiarity with both cans
