Well im fixin to order a M700 BDL LSS .375 RUM and I have some questions for people who have one of these beasts.

1. Have any of you had problems with stocks cracking?

2. What Scope do you suggest it gets topped with?
( I was thinking that the Luepold VX-3 2.5x8x36 with 2 piece dual dovetail mounts would work...any comments?)

3.Just how nasty is the recoil???

4.Suggestions on a muzzle break.

Thanks!

Trap Shooter,

another option would be to buy a cz550 or in .375 H&H and run a .375 RUM reamer up it. I feel you would have a better rifle than a Rem 700, also plenty of room to seat projectiles. The .375 RUM seems like a good round.

1. Have any of you had problems with stocks cracking?

No action is better suited for big recoil than the Rem 700. Very big action recoil lug and lots of stock material behind the recoil lug. Rem don't use a barrel lug on the 375 Ultra African Big Game and unless they have changed the 416 Rem does not have a barrel lug.

2. What Scope do you suggest it gets topped with?
( I was thinking that the Luepold VX-3 2.5x8x36 with 2 piece dual dovetail mounts would work...any comments?)

Dual Dovetails with the bases epoxied to the receiver is about as good as it gets. Use a "glue" epoxy rather than filling type epoxies like Devcon.

3.Just how nasty is the recoil???

I have never shot one but have fired plenty from either side of the 375 Ultra, that is the 375 H&H and 378 Wby and I would say it will be quite heavy going.

4.Suggestions on a muzzle break.

I don't think the 375 RUM needs a break.

I agree with everything thak Mike375 and PC have said. I have both the 375 RUM M700 LSS (26") as well as a CZ 550 Magnum action with a Winchester barrel that had its threads cut off to 23" then rechambered as 375 RUM. I like the CZ-Winchester hybrid best.

The CZ action was an AHR without the CZ billboard rollstamp. The Winchester barrel had the "H&H" obliterated and re-engraved by a master engraver to read "RUM" pretty as you please, and a custom walnut stock to boot.

It sort of looks like Axel's dad reworked an M70 custom rifle to make it look like the CZ 550 Magnum, but the only identifying engraving or stamping is all Winchester and AHR. Maybe AHR that means "Axel hunting Rifle?" Great resale value, not! Well it was a good and accurate barrel as a .375 H&H, and I hated to see it go to waste.

The M700 is accurate and will serve as a shop mule for load development, whenever I run out of factory loads, which the Remington ammo factory did a very good job on.

I appears that my load to duplicate the great Remington factory load will be:

Remington .375 RUM brass (of course)
Swift 300 grain A-Frame
Remington 9-1/2 primer
IMR-7828 at charge of 93.0 grains

This load gives just under 2800 fps in the 23" barreled "Winchester-CZ hybrid," and just over 2800 fps in the 26" barreled M700.

The Win-CZ has almost no freebore, just a leade. The M700 has about 0.175" freebore (standard 375 RUM ?)as best I can tell.

Did I say that I like the Win-CZ better than the M700?

ovis,
Good point. I think the .375 RUM and the .375/404 Saeed are within one grain of water case capacity, nearly identical. Saeed's loads should be a good guide for use with the usual handloading precautions.

I'll leave the choice of CZ or Remington to the other posters. As to the recoil, it will be felt from the bench and not in the field - just like any big bore. If you get a muzzle brake, make it a detachable one and don't plan to use it in the field. I have a 378 Wby. with this configuration, as well as a 358 Norma and a 338 Win Mag. None of them get to wear the muzzle brake when hunting,or when doing the final sighting in. But for practice, they ALL don the brake.

I've liked the KDF brakes. You might also want to consider a mercury recoil reducer in the stock.

My 375 ultra is a 700 SS SYN. It kicks like a mother----er

I don't mind the recoil from standing but it knocked the crap out of me last time I shot it off the bench. The scope hit me in the head four times. Only a little blood.

To me this rifle is no fun off the bench.Even with speer 235 grainers.

I can shoot my m70 300 ultra all day from the bench. 200 @3200, 220 @3050,240@2850

I was shooting with a carboard box under the front of the rifle and no rear bag in my t-shirt. Did group well though.

My rifle needs a better recoil pad for shooting with a t-shirt. And I am considering getting it breaked with a Vais.

-------------------------

I would like to put a m70 classic together with a little more weight to it and a good recoil pad. I don't think this would need a muzzle break.

------------------------

I like the cz-550 idea but to me those rifles are huge.
They are built for a 6'-6" 300 pound man.

I am only 5-10 200lbs.

Trapshooter - check into the Leupold VX 2 2x7 scope, has lots of eye relief - for sure, use he Leupold dual dovetail mounts as suggested. Off the bench, use a Past recoil pad and maybe a bag of shot between you and the buttpad. KMule

1. If you crack the laminated stock that came with mine you will also have medical bills that exceed the cost of a new stock.

2. Your scope choice is fine, but give my recoil suggestions below some thought.

3. 375 RUM recoil is too heavy for good work from the bench without additional protection. My solution to not only protect myself, but my optics, was to simply acquire and modify a second stock to achieve a total weight of 12.8 pounds. Both stocks have Limbsaver pads and an additional pad can be worn at the bench. The heavy stock is simply a joy to shoot, and I now carry it in the field when there is not a lot of climbing involved. Knowing how to use a good sling in the field solves most of the flatland carry problems.

4. It definitely does not need a brake with the heavy stock, and is still fine for hunting with the light stock. If you use the light stock for extensive target work with heavy loads, the chances that you will change zero is pretty high, even with the optics set up you suggest (If you do add a brake, this will make it worse). However, it takes only about 2 minutes to swap stocks and with a little work, you will be able to predict changes for
poi when going from the heavy to light stock...mine shoots 2 inches high with the light stock.

Finally, it is worth noting that the 375 RUM retains its accuracy very well with reduced loads, and you can get fine results loading to 35 Whelen through 375 H&H energy levels. The 375 H&H loads recoil a bit more in the light stock than the heavy 375 RUM loads in the heavy stock. The H&H loads in the heavy stock are a dead ringer for factory 30-06 loads in an 8 pound sporter.

What is the max velocity with a 270 grain bullet in a .375 RUM? Like a rihno or woodleigh?

The Nosler manual 5th ED says a bit over 3000 fps.
