Anybody own a 350 Remington Magnum?

[Rem280]

Try Superior Ammo.

TY! So many nice rifles in this caliber I need.

@Rem280
Just use 7mm mag cases and a set of forming dies and you will have all the brass you ever need for the 350 rem mag

Try Ammo Seek

Looks like $7 to $10 per cartridge. If you are serious about using the 350RM, you might consider reloading for it.

Or get a 35W and call it a day.

.350 Rem Mag has been a favourite of mine for decades... I have owned many rifles so chambered. I have taken a great many bears and moose with various .350 RM rifles. I currently have two Stainless Ruger M77 Mark II rifles that left the factory as .350 RM's, but converted one to 6.5 Rem Mag... they make a great pair of rifles for most game... certainly everything in North America.

Can factory ammo be found anywhere? I need one of these and ammo is nonexistent

For .350 RM, your best bet in finding NOS factory ammo is on one of the auction sites. Otherwise, unless a custom ammo outfit is making it, you’ll just have to source the necessary components and handload it yourself. Brass is the biggest issue but it’s out there occasionally.

Since my earlier post detailing my M600, I acquired its successor sibling the 20” model 660 in .350 Rem Mag.

We did a similar upgrade package as on the former: a well-fitted, black Kick-Ezz recoil pad; a steel trigger guard to replace the warping plastic factory guard; replaced the factory front sight with a Williams fiber optic sight and then zeroed the rifle @ 100-yds with factory 200grn ammo and an equivalent 200grn handload.

I’ve since added a low-powered, low-mounted Leupy scope and will add pics at some point.

Following up on my previous post for the Remmy 350 Mag fans, here are a couple of recent pics of my models 660 (20” barrel) and 600 (18.5” barrel). Both have been ‘lightly’ customized by my ‘smith as described in earlier posts.

The M600 (bottom) is a dedicated iron-sighted bush/brush carbine intended for short-range hunting where shots will rarely exceed 100-yds, let alone 50. It’s light, compact, and perfect for tree stand use in thick-timbered areas.

For the M660 (top), after getting the iron-sights zeroed an inch high at 100-yds with 200-grn factory ammo, I wanted to keep to a light, compact optics set-up as much as possible. We used a Weaver base, Leupold QRW2 rings (low, 1”, matte), and a Leupold fixed 2.5x20 FXII UltraLite scope (sku # 58450).

That set-up yielded plenty of magnification for a 200-yd zero, but a 150-yd zero is really the more practical max for the species and areas I might hunt with a .350 Magnum, which obviously won’t be sniping at Montana prairie dogs at 600-yds.

In the pics, the stock pak on the M660 is an old Eagle Industries unit. It’s somewhat padded and the comb height allows for a perfect cheekweld with the UltraLite. The zippered pouch keeps the ammo and scope ‘dope’ handy. (Not shown is a 2-pt QD Galco Safari sling for the M660. The M600 runs a 3-pt QD Ching sling)

The M660’s 2.5” longer tube over the M600 puts it in the category of what used to be called a “short rifle.” That bit of extra length increases projectile velocity for more down range punch. I’m stupid-busy this month but when I get back to my reloading bench in September I want to work up a 250grn load for this one. The 200grn handload (over Varget) that I developed for the M600 essentially duplicates the factory ammo and shoots just as well out of the M660.

Awesome rifle and caliber. I lust after one in a BLR

That would be a custom rifle, I don't think the BLR was ever made in .350 Rem Mag... I am open to being wrong in that, but I have never seen one.

Yep, and aside from being the world’s first short magnum, the real genius of the cartridge is that it can be loaded up or down as needed, with a good variety of .35-cal bullets, for the particular species of game you’re hunting.

That means you can shoot Midwest deer at mild 30-30 levels, or step it up a bit to the old school .35 Remington level, or for the really big stuff like bears, moose, caribou, or elk, run it full-throttle at the magnum level.

Any cartridge can be loaded down... the .350 Rem Mag cannot be assigned "genius" for that. Many caliber accept pistol bullets and have a wide range of bullet weights available. As for powders, most can be made to work with filler, or the newer bulky powders can yield lower velocities with a full case. I feel the real power of the .350 Rem Mag was in the attribute for which it was originally designed... namely, achieving tremendous power in a short case. I load mine to the hilt with 250 grain Partitions and have witnessed dozens of times how it drops the Hammer of Thor on large game.

I have a Remington Model 600 in 350 Rem Mag. When it came into my possession, it had been modified quite a bit from its original configuration. It sported a nice hardwood stock with a schnabel forearm and aftermarket bottom metal. Though the wood was pretty, the forearm length and barrel length were not proportional to one another, which really detracted from the aesthetics of the rifle. The vent rib had been shortened and the front sight moved rearward in order to accommodate magnaporting near the muzzle.

As received, the only thing the rifle had going for it was its light weight and easy handling characteristics. It was not pleasant to shoot and accuracy was very poor. The cold bore shot could be placed predictably. The second shot would normally stay within 3 or 4 inches from the cold bore shot. The third shot would not reliably stay on a paper plate @ 100 yards. This was, by far, the worst case of "heat walk" I have ever seen.

Working with a friend of mine, we removed the vent rib, replaced the atrocious factory trigger with a Timney, and fitted a picatinny rail. With tuned handloads, we were able to get the second shot down to about 2 inches from the cold bore shot, but the third shot still would not reliably stay on a paper plate @ 100 yards.

I decided that a re-barrel was required to get that rifle shooting to a reasonable standard of accuracy. I got the rifle back from the smith yesterday. Initial, very informal, shooting shows promise with factory Remington Core Lokt ammo. As mentioned by others in this thread, it seems the mag length is the limiting factor for bullet weight and overall ballistic performance. I am thinking this rifle will likely be at its best with 225 grain lead core bullets or 200 grain copper bullets. Barrel length is now 20 inches. I am planning to do load workup with Ramshot TAC and Winchester Staball Match. Will share results as I have them.

Here is my rebuilt Mohawk:

 

[benchracer]

Remington factory 200 grain CoreLokt ammunition averaged 2682 at the muzzle. Handloads developed for the previous barrel averaged right at 2700 with the same bullet.

I am getting ready to begin load development with the 200 grain CoreLokt bullets I have on hand. I also plan to obtain some Sierra 225 GameKings and some Barnes 200 TTSX for load development. I am looking at testing the following powders: AR COMP, CFE 223, Ramshot TAC, Staball Match, and N540.

Based on initial QL work, accuracy with the 200's should show up between 2840ish and about 2900 with the various powders. Accuracy with the 225's should show up between 2630ish and 2690ish.

@benchracer
I get superb accuracy out of my Whelen with 225s pushed comfortably to 2,900fps with cfe223. You should be able to push those 225 gn Game Kings pretty hard out of your 350 REM mag.
The beauty of then is they are a short bullet compared to the accubond so don't take up as much room in the case.
Just my thoughts

I liked my 660 so much that I bought the model 673 in the same caliber when it came out. It is one of a few guns I have bought that I haven’t shot or handled before buying. I picked up two more boxes of ammunition as well when Remington started making it again. That was in 2004.

 

[hoytcanon]

I use the 250 Hot-Cor's in my Whelen's and mostly 250 Partitions in my .350 Rem Mags...

Why?????

[Ruraldoc]

I owned a tang safety Ruger in 350 magnum.

I used 200 grain factory ammo on deer and handloaded 225 grain Bear Claws for elk.

Not sure why I sold it other than my 35 Whelen which was pretty much the same thing.

Now I use a 9.3x62 which is also in the same class.

You don’t appreciate how hard these rifles hit game until you see it.

Decades ago, my dad bought a Rem 600 in .350 Rem Mag. A couple years later he sold it. A few years after that he decided he missed it and started tracking it down. It passed through 2 or 3 hands before he eventually found it and was able to buy it back.

I inherited it a few years ago. I can't say it's fun to shoot, but it's a really nice gun to carry in heavy timber. Along with the rifle came plenty of brass, dies, and bullets. I don't really "need" it, but it will always have a spot in my gun safe.

Thanks dad!

@BryceM
Who cares if you need a rifle or not. It's a matter of want not need.
Your 350 should NEVER have a spot in your safe it should ALWAYS be out hunting not hiding in a dark dingy safe.
