What are 375 Ruger users doing for loads?
what are the purposes for various loads?

This week I am loading up 100 rounds for my wife's 375 Ruger. She is aiming at comfortable H&H levels rather than chasing Weatherby levels.

One load that may be new to those on the forum is a 200grain GSC HV in .375". Her 20" barrel puts out 3183fps with 83 grains of IMR 4166. She may decide on 81grains of 4166 for 3117fps. The 4300ft# is a typical factory level for the H&H and comfortable in her little Ruger Alaskan.

Maybe even more remarkable is that components for the 375Ruger were available on the shelf in a place like Fresno CA. Imagine that. We could pick up an extra set of dies and brass without a special order. That should testify to the growing acceptance of this great little round.

And what use for the 200-grain GSC HV?

General plains game. It shoots flat like her 270, at least to 4oo yards, and the mono-copper construction will be enough for anything shy of ele and hippo, which we don't hunt. Gina of GSC says that SA farmers have been favorably impressed with this little bullet. It will do in a pinch for broadside or facing buffalo, but LadyT will be looking to 250TTSX and 260gn Nosler flat-point solids when and if she does her first Mr. Nyati.

I am using H380 with a 270 grain TSX. I have not chronographed the load.

Other than applying a light crimp with a Lee Factory Crimp die, it is straight from the Barnes #4 manual. It is one grain under the book maximum.

This load shoots very accurately in 3 different rifles. Two of the rifles have been used on moose.

This is my one and only load for the 375 Ruger.
Eventually, I may attempt to fine tune. But as is, it works well for me.

Edited to add:
The 375 Ruger is one of my favorite cartridges, along with the 338 Win Mag and 416 Ruger.

I used 80 grains of IMR4350 with a Hornady 270 grain bullet. I killed an interior AK grizzly with it this past June.

250 grain Sierra Game King over 71 Gr Varget. My to go load for pigs and white tail. Very accurate in my Hawke eye Alaskan out to 400 yards.

375 Ruger Guide Gun 20" barrel

78.5grs. of RL17 powder with 300gr. Nosler Accubond traveling 2590fps average this is my elk load. 1/2" 3-shot group

73.0grs. of RL17 powder with Woodleigh 350gr. PP traveling 2391 fps average this is for dangerous game load. 1" 3-shot group

Both using Winchester Large Magnum Rifle Primer and both bullets seated 3.385" COAL. Lee factory crimp die used with heavy crimp.

Barnes 300 TSX moly
80 gr RL17 COL 3.10"
Mildly compressed
Average 2676 fps
Sub-MOA

CEB 275 Safari Raptor TSG
80 gr RL17 COL 3.30"
Mildly compressed
Average 2657 fps
Sub-MOA

Both loads are very comfortable and easy to shoot
in the 375 Ruger Guide rifle. RL17 is the go-to
powder for the 375 ruger.

250 gr. sierra gk over 72.5 gr re 15 accurate and easy to shoot. My black bear and anything else in NA load.

Would like to see if anyone else has loads - in particular I want to shoot trailboss and some 285gr lead rn for "practice". Maybe use them on whitetail next year, as a full 375 seems like overkill. (Part of me feels like I am just going to duplicate a 20 guage shotgun slug, which we were able to stop using about 10 years ago when rifles were allowed in my area of NY). So any reduced/ trailboss loads/experience with lead?

So we made a decision on the 375 Ruger loads.

We loaded up 50 rounds of the 200gn GSC with 81 grains IMR 4166 in new Hornady cases and Rem9.5Mag primers. Velocity of 3100fps in the 20" barrel means that this load will shoot much like a 300Weatherby out to 300 yards.

For those considering a softer deer load, this should fit the bill. The recoil with a 200 grain bullet is quite a bit less than with 260, 270, 285, and 300 grain bullets of standard H&H fare.

We also loaded up 40 of the 250gnTTSX (85gn Rel-17 for 2820fps) and 10 260gn Nosler solids (83gn rel-17 for 2780fps) for larger game (i.e. eland and buffalo) should the opportunity arise. The heavier rounds shoot about 6-inches lower and a bit to the right of the 200 grain rounds in my wife's gun so a person needs to sight in and hunt with one or the other on any given hunt.

I load 79 gns of R17 behind a 300 gn partition in my Satterlee arms 375 Ruger for a vel of 2710...24 inch barrel

M-98 How does that load work on Aussie Buff ?

I think the answer to your question is very simple...ask yourself why and what's the need for a .375HH since both are very similar cartridges performance wise.

The biggest pro in favor of the Ruger cartridge is that there is no need for a long action, making a more compact and light rifle. This is a very desirable aspect in my book.

Other than that, I'll never use one.

IMHO, A .458WM is suitable and better than any .375 load of both chamberings.

Well, my wife is 110 lbs and much prefers her 375 Ruger over bigger stuff. (She has only shot a 416, never considering my 500). And you know what? Her 375 might be easier for hitting the heart of some hartebeest at 235? 260? 285? yards. Sometimes it's hard to tell just how far a shot is and a good cartridge allows one to still place things right on the top of the heart.

PS: we went with the 81 gn 4166, 200 gn GSC at 3117. It'll do whatever she wants on PG.

i have not used the 375 Ruger on our buff down under...i used a 375 h@h with jack carters 300 gn bear claw bullets , and used the 270 win with some 140 grain soilds that jack made for me how ever i would not hesitate to use it
i got 3000 fps with 82 gns of R17 behind a 260 gn nosler
R17 seems to sing in the 375 RUGER

I have always used the 270grain interlock on boar, elk, and deer. I did use a 300grain DGX on a deer.

I much prefer the 375 Ruger if I may need Shoot at any range that needs a scope.

I have treated it like I think most people have treated the 338WM.

It is my favorite cartridge and caliber.

Good call.
In truth the 338WM and 375's are very very similar for practical hunting, but the Ruger is Tanzania-legal for my Lady.
