375 Ruger in Mossberg Patriot

[Shawn.54]

I have one of the Mossberg Patriot in .375 Ruger and I'm looking for more information/ other owners to compare loads problems.

This is a hard cartridge rifle combo to get information on at times I think I have the only one.

Thanks
Shawn

A number of articles have been written on the .375 Ruger in "Handloader Magazine". It's an easy cartridge to load for.
With the 200-250gr bullets, RL15 is your powder. Good in the 270 for slightly reduced loads.
With 270-300, it's H4350 (though RL17 should do equally well).

Check in on the Ruger web sites for better responses.
For deer loads, 225gr Hornady and 77.0gr RL15. Accuracy not max at 3,000fps. Ditto 235 gr Speer.
250gr Sierra, 75.0gr RL15, 2,800fps. Sub MOA accurate.
270gr Hornady 72.5 RL15, nice shooter load, 83.0gr H4350, factory published load duplicate 2,800fps.
300gr Nosler 80.0H4350, anything in N. America load. (Most of Africa too, or 300fmj, for everything else.)

BTW, my rifle is a Ruger M77 "African". I'm told it's been to Africa and took numerous plains game including a Cape buffalo.

I started out with GS Custom 200gr HV and they have worked great and with Reloader 15 grouping well under a inch at 3213fps average in my avatar it is the black bullet.
I doubt I'll ever get to Africa but if I do that is what I'll be taking they are used on every thing up to and including Cape buffalo.
The other cartridge in the avatar is .35 Whelen which I gave my son for graduation present so I had to buy the .375 .
