I have some of those 2020 Sie, and I fit one into a fired 7.62x25 case, OAL seated at the canular was the same as the factory 85gr cartridges that I have. Wether that blunt nose would hamper feeding is the other question. It might pay to make some dummies and see if they will feed manually.
Lee lists loads for up to 110 gr with AA9, but I can't find anything for H110. Are you intending to use this in an semi-auto pistol?
