New Project - 375 Ruger
With very helpful advice from fellow AR member joester and also from Biebs I am going to build a 375 Ruger on a Browning BLR.

A browning BLR in 243 was my first rifle that I sold to buy a f*cking Glock - how stupid am I. It was the only gun I ever sold - now I just and hold.

Just ordered a 7mm rem BLR that will become the foundation of the new rifle.

BLR in 375 Ruger will come as close to getting a crocker on a rifle than buying a blaser.

Sounds like a good build.

You'd better start working out now. If you're determined enough, maybe by the time the rifle is done you'll have shoulders adequate enough to stand up to it :-)

Biebs - Some of us are man enough to shoot big bores without a 3 pound Mercury backstop in our 11 pound blasers dancing

I hope you are going to use one of the older BLRs with a steel frame instead of the later models that are aluminum alloy.

That said, we want videos of your first trip to the range; and be sure to start with factory loads from the bench to sight in. :-)

This will be a neat build to follow. If I remember correctly, someone else on here did a 416 ruger on a BLR?

Ruger 375R alaskan weights 8 pounds

Browning BLR weights 7 pounds 12 ounces

Should 4 ounces matter than much for recoil.

The straight stock on blr might not be good for recoil.

It depends on where the 4 ounces is. A straight stock shouldn't matter as long as it fits you.

I will point out that Ruger is now adding their "Ruger Muzzle Brake System" to all their 375 Ruger rifles, still at 8 pounds. A brake is an option for you to consider. Still, that's a lot of recoil for a rifle weighing less than 8 pounds. You might consider a slightly heavier and/or longer barrel. A little weight can be added to the stock to balance. I would try for 9 pounds but that's me.

A 9 pound rifle firing the 270gr .375 Ruger load will still generate 41.3 ft-lb of recoil at 17.2 fps. That's the same as a 400gr bullet from a 9 pound 458 Win Mag with 41.7 ft-lb of recoil at 17.3 fps. Shooting a 7-3/4 pound 375 Ruger without a brake would really, really smart.

This is a 416 Ruger on a BLR. I never had a problem with the rifle except that it would only hold two in the magazine. If you put the third in the magazine the recoil would shift the shells forward and would not allow it to feed the next rounds. Also, It would not handle the same loads my 416 Ruger bolt will handle. The tops loads for the BLR 416 Ruger would cause a tight stiff opening lever for the BLR. Recoil was not as bad as one would think. The load in the video was a 350gr Speer Mag tip @ 2350fps.

This reminds me of an article I read about a 458 Winchester magnum BAR. The gentleman that built it started with a BAR in 338 Winchester magnum. He said the rifle performed well but he did complain about the recoil. Anyway, it couldn't have been too good an idea because I've never heard of another one since.

Nice video - made my day.

I am okay with recoil up to a 458 lott - I actually like shooting my 375 H&H and 375 Ruger - the recoil is very manageable. I have shot my 375 H&H a fair bit.

When the BLR comes in - I will take it to the range and shoot some 7mm to see the recoil. The only gun I hate for recoil is a custom 7mm rem alaskan wilderness rifle. My most accurate rifle that I hate to shoot.

This ruger 375 project should be fun - if it turns out well as I expect - I will most likely build another gun.

I also figure adding a scope and mounts would add a pound or so.

The practice shots with the 7mm will give me a good idea of recoil. I hate 7mm - have a sharp kick recoil versus 375 which is more like a push.

Sounds like a follower/spring issue...both moving to the rear under recoil which allows cartridges to tip nose down (caused by heavy weight if bullets) rather than ride level.

I read about the same issues with the larger caliber B&M cartridges in the M70 WSM magazines. Solution was to pin or JB Weld the spring into the proper location on the floor plate so that it wouldn't move. FN has resolved the issue by revising the floor plate on the SC manufactured M70s so the spring can't slide rearward once installed.

Likely wouldn't be a huge market but I foresee a ready market for aftermarket BB magazines for the BLR.

Got the 7mm rem blr - no issues with recoil. Lighter than the recoil of my Remington 700 that I hate.

This will be a fun project.

Only think I don't like is the magazine - not sure the latch is super secure

Really like the safety - there is none - you need to cock it with the hammer to shoot - perfect observable and manual
