So I've had my Spanish Mauser for a few years and always hated the way the sights were 2 feet high at 100yds. The Pyramidal front sight was also stupid, so I've decided to replace the sights with a Williams ramp with brass bead and a peep sight so I can ring the best accuracy out of this almost 100 year old Guardia civil carbine.
Heres the obligatory pic of it in its original form. With some of its straight stocked stablemates.

I tried reloading 140gr for this rifle and accuracy was shotgun like, However once I switched to 175gr Federal factory loads accuracy was very good, about 2" at ~100 yds with the old iron sights. My reloads with Hornady 175g bullets also showed promise. This would suggest my rifle is twisted to like the heavier bullets.
This was a few years ago however and I have since misplaced my load data.

Anyone have any good loads for a 175gr in the Mauser?

I would like to replicate the Factory Federals listed MV of about 2400fps (obviously a bit less in this shorter barreled rifle) as I intend to use this rifle for some tree stand hunting this fall.
I noticed a pretty disparate data on the Hodgdon site for H414 vs. my Lyman 49th edition. The Hodgdon lists a max of 37.0gr for 2119fps and Lyman 44.4gr for 2464fps. Do you think 44gr of H414 is out of line for this 1893/95 Mauser action?

I do have quite a few powders around and would like to use one of the ones I usually stock, H414, H4895, and Reloader 15 are my preferred choices.
 
I think you should start with a 40 gr load of H414 and work up, checking for pressure signs. My Hodgdon Reloader's Manual says that 44 grs of H414 with a 175 gr bullet generates 48,400 CUP. That's on the high side for a 93/95 Mauser.

The Hodgdon Data Manual list a starting load of 35.5 grs of H4895 with a 175 gr bullet (2164 fps) and a Max of 39.5 (2466 fps).
 
Thanks for the info
I'm surprised by that H4895 load, as the Hodgdon reloading manual doesn't list one for 175gr in the Mauser. I think that 39.5 would be way too hot.
Trouble is I can't really work up to pressure signs in the Mauser as it's action is really only designed for a max of 45000 CUP and nothing will really show up until far past that pressure.
I think I will work up a load with H414 using my Chronograph with the aim of getting 2200 fps out of the 21" barrel and consider that good enough for my purposes. I agree that 40 is a good load to start at, I'm thinking 42gr would be as high as I should go.

That H4895 load was from the Hodgdon Data Manual 25th Edition.

It also has loads for H1000 with a 175 gr bullet:

50 grs gives 2309 FPS for 36,600 CUP

53 grs gives 2419 FPS for 41,400 CUP
