Has anybody reloaded a 375 Ruger and if so did the fps equal the factory loads? Thx

The short answer is no and yes.

You can reach 2783 fps at 58,400 PSI, 57 fps short of the factory 2840 fps, using a compressed load of 83.5 gr. Hodgdon H-4350 with the 270 gr. Hornady SP bullet. Hodgdon no longer lists loads as compressed/maximum on their website so I don’t know how much additional powder would be required to match the factory loading.

However, the factory loading of 2660 fps with the 300 gr. Hornady bullets can be reached at 59,600 PSI using a non-compressed loading of 80.7 gr. of H4350.
