BEFORE.....doing anything else
Concur with MEHavey's advise, 15 gr 296 with a 110 bullet is possibly an over max load for your M1icon. The residual pressure in the chamber still has the case gripping the chamber when extraction begins. This is no doubt what is causing the malfunctions. Suggest dropping at least to 14.5 gr 296.
