375 Ruger in a Flat Back receiver

[noyb72]

Good evening,
I am a fan of flat back receivers. There is a lot of nostalgia in hunting and I've had one for over 35 years. I am now in a position to collect / build a series. They will be right handed, blind magazine, wood stocked and blued steel. Most will be on a 06 case (25, 280, 30, 8 or 338, Whelen (35, 38, and hopefully 400) with the skinniest barrel I can convince someone to make.

I would really like one big one in 375 Ruger, but I am not certain that can be done. I know that ll of the flat receivers have small shanks, can you put a Ruger chamber reamer into a small shank barrel? As I understand it, the chosen rifle should start as a Magnum due to the unavailability of magazines, is there anything else I should consider in choosing the donor rife?

Thanks for the help!

The Small shank receiver is just fine with the 375 Ruger. Several have done it.

Great,
Just what I want to hear. I think a 20 inch barreled 375 will be just the ticket if I ever have to take on a brontosaurus.

Just make sure you make it heavy enough. I have a factory model 116 in 375 Ruger. It was extremely light and I got a major eye brow cut the first time I shot it. A little more weight and a scope with longer eye relief and it is much more manageable now. That thing is pretty fierce in a 7 pound rifle though.

That’s the case with any of the Super /Ultra Magnums with no Brake.

Oh yeah, I forgot to mention, I did have a brake made for mine too. Now weighing around 12 pounds, a brake, and a scope with plenty of eye relief, it's very manageable now.

Thanks for letting me know about your build. I have a weird eye issue that makes long eye relief scopes much more useful, so that is covered. I don't believe I will want to carry around a 12 pound gun, I'll be shooting for around 8 or a little more all up. I fish in black bear country, and will start spending some time fishing in brown bear country soon and I like having a long arm on me just in case. The 375 Ruger seems like a natural for the big bears and will certainly do for any black bear alive regarless how unfriendly it is feeling.

Thanks again

Enjoy the build. The 375 is good bear medicine for sure.

A while back, I built a 375 Ruger on a Savage flat back control feed small shank action, 22" barrel, with a Bell and Carlson stock and it was great.
Then like a dope I sold the barrel. Then dopey #2 move, I sold the action.

I oogeled and augelled the Ruger 77 model .357 bolt action rifle. But I think you are suggesting necking a .30 .06 case to that caliber? There should be some small shank barrels in big 30 cal calibers available on a short action.

I have one of those round front/flat back actions, played the dickens finding the correct set of scope bases for a rifle scope and it would be much better shooter for my eyes with a scout scope.
