Finally found a load my Shadow Systems MR920P doesn't like - IDPA - 12/21/2024

Today's IDPA match at Cleveland Hunting Rifle & Pistol Club went great, aside from several malfunctions due to a lower powered 135 grain competition load that my Shadow Systems MR920P obviously doesn't like. After the first malfunctions, I assumed it was because I was shooting a dirty gun, so I cleaned & lubed it between stages. After the next malfunction, I decided to switch to a 124 grain load, which ran fine the rest of the day.
