7.7 Jap Loads

I have an original 7.7 jap. Just wondering if someone could look up the min/max load for a 174/175 gr sierra MKHP bullet tip with IMR3031/IMR4895 powders. I do not have a current sierra book.
If you have a pet load and wouldn't mind disclosing it that would be appreciated too! It will give me a starting point!
I know factory ammo in WWII was 175 gr bullet at 2400ish FPS. I will be trying to match that load so the sights will be accurate for at least 200 yards.
I believe that the 175 gr MKHP will have a better BC than it was in WWII so the sights might be wrong pass that. Giving it a more flatter trajectory. Wouldn't shoot a deer past 200 yards with that rifle any way!
Thank you for your help guys!!

Any bullet designed for the .303 Brit, 7.62x54R Russian, or 7.65x53 Argentine Mauser will suffice. The Rem 180gr RNSP is an old personal favorite.

I've had no trouble running a 180 gr round nose with 45 gr of 4895. This still is by no means a real rip snorter load, and you could use it with the 174 gr as well. In fact it is 1 grain UNDER a max load for a .308, a significantly shorter cartridge. Usual caveats apply, start at 10% under and work up.
