375 Ruger Reduced Loads for deer and black bear Hunting

[shortstuf92]

I have a couple of 375 Ruger rifles and would like to find a reduced load using either the 235 grain Speer bullet or the 270 grain Speer bullet. The reason is I would like to get more usage out of these rifles. I would like to get around 2500 to 2600 fps out of these bullets. Has anybody tried these or has any good load data to achieve this? Thanks

Maybe take a look at H4895 data. It can be downloaded to about whatever speed you want with little to no danger. No experience downloading that big Ruger case though.

The following site has load data you can buy for the 375 Ruger with Hdy 225 gr Sp bullets:

The following will provide load data for the 375 Ruger with the Speer 235 gr Hot Cor:

These loads are hotter than the Hdy loads.

Hope this gives you some starting points.

For a similar comparison:
I have a 376 Steyr (21" barrel; in a mannlicher stock), so less case capacity, but performance not far off from what you are looking for.
Hornady provided ammunition with the 225 gr load, but down loaded it to the same velocity as their 270 gr ammo (2600 fps), to try to match point of impact for both loads, in the event that someone wanted to shoot smaller species when opportunities presented themselves on hunts for larger species.
The lighter load produced 1.125" 5-shot groups at 100 yards. The 270 gr load, produced 0.625" groups at 2507 fps. Unfortunately, I do not recall if it matched poi, and I did not chrony that ammo.
I have not tried to load either the 225 gr Hdy or 235 gr Speer, as I stick to one load per rifle for hunting.

I also tried a load with H-335 and the Sierra 250 gr SBT, and got 1.250" groups at approx 2754 fps (sorry, did not chrony this load at the time).
I haven't hunted with either as I have a good load with H-335 and the 260 gr AccuBond, at 2632 fps and 0.535" groups, and a SD of 7. It has accounted for elk and bison so far with this load.
