WR: I agree with your logic; I don't have 'regular TP' to compare overall length to the THP. Side by side the RN and the THP of the same weight, shows considerable length difference. Not in front of me currently, I don't have the actual measurements.

My concern was how that shorter OAL would be affected in chamber pressure & groove engagement, from the standard RN.

Tomorrow I will do further measurements & probably just load what I got already.
