.35-300win


Registered Users do not see the above ad.


Is there a cartridge based on a .300 Win Mag case necked up to .35 cal?

I mean I am sure there is, but what type of performance does it get? Are there variations?

A friend of mine has had one for at least 20 years. He had his 300WM re-bored after it had sand-blasted it's throat away. No problems in .35 cal. I will get some of the data and post it for you.

.

It is called the .358 Norma Magnum. It is not the .300 Win.Mag necked-up but is very close. Case capacity is 86 grains of water. It can be chambered in a 30-06 length action.

Then there is the big boy; the .358 Shooting Times Alaskan with a case capacity of 104 grains of H2O. It requires a true magnum length action.

The .358 Norma is shorter than the .300 Win. It seems to me a .35-300 would have more capacity (depending on how the shoulders were blown out).

The 358 Norma 338 Win and the 300 Norma are all built on the same case, just a pinch bit shorter than the 300WM. I would not use a 300WM cause of the short neck, it would only get worse the larger you go with the case.

I shot a 308 Norma for years. Velocities are exactly the same as the 300 Win mag with the advantage of a little longer neck.

The 358 Norma is a great cartridge if you don't want to wildcat. If your looking for maximum velocity you might consider the 35-378 Weatherby or the 35-338/35-375 Remington Ultra-mag.

The cartridges that are already out there such as the 338 Ultra-mag or the 338-378 Weatherby mag or the 8mm Remington magnum are available and give you a very flat shooting high power package compared to any 35 caliber bullets available.

If you want to go up in power and still keep a rifle that shoots flat to 400 yards plus then the 375 Ultra-mag and the 378 Weatherby are designed just to do that and give you more power and better trajectories than any of the 35's.

I shoot Remingtons 8mm mag with 220 grain Sierra boattails at 3080 fps and it's a great elk rifle out to 500 yards (the limit of my shooting ability at this time in my life). It's quite capable of any 300 magnum trajectory except for the new Ultra-mags and the big Weatherby of course. I can shoot bullets up to the 250 grain Woodly if I need more power.

I talked to Greg on the phone and he said that he gets 2900 fps with a 250 gr projectile from the .35-300WM. He said that it is not maximum for the bullet weight but is very accurate. He will e-mail me the load and any other info he thinks of and I will post them here. His reasoning for the wildcat over the other Magnums was that he had the cases and the dies were easily modified for the caliber change.

That's pretty impressive. 500 fps over the max .35 Whelen and .350 Rem loads. The Norma max is at 2800, with 2700 looking more reasonable to me.

I bet 225 Nosler Accu-bonds would really reach out there in that rifle.

Be careful of the 225gr Nosler BT and now AccuBond ... they're a long projectile. I know of one 35/338RUM built in Australia on a Rem700 action that requires reasonably deep seating with that projectile to feed through the mag box. Redding has the dies though if your after one. I've necked up 300RUM to 35cal to take a look see ... but if I ever built it, it would go into a Brno 602.
Cheers...

Good point. I tend to use Model 70s or other Mauser action weapons which usually have longer magazines. Case in point, my Model 70 7mm WSM has no problem with longer bullets, even though the same caliber in other rifles does have restrictions with longer bullets.

Bird Dog,

I don't know how much power you're looking for, but my .358 Norma factory 250 grain loads deliver 4200 ft-lbs of muzzle energy. I've had some pretty experienced gunners stop with one round.

Yeah that is an impressive round no doubt about it. I love .35s, but am leaning towards a .375 H&H simply because, if by some weird happening a Brown Bear or African encounter ever happened, it seems a more practical choice.

You might also look at the new 375 Ruger. Same power as a standard 375 H&H in an 06 length action.

Hey ... we'd all like to hunt Africa, but realistically what are the chances of getting a hunt on DG where the 375cal legality issue comes into play??? Plains game ... maybe, but then you dont need the 375cal . If Brown Bears are a real possibility in your neck of the woods ... I seriously doubt that a 310gr Woodleigh at 2500+fps is going to bounce off and if it does there's always the 310gr FMJ .
A true lover of the 35s would never consider a 375cal , they'd build their .35 and then get a magnum .416 ... actually we're an odd bunch ... it'd probably be a 0.411" .
For my hunting ... a compact Ruger 350RemMag pushed the 375H&H out of the safe.
Cheers...

There is no need for a .35, considering that the .338's and .375's are in existence.

Well I actually had a chance to go to Africa and passed. I've been in the Eastern hemisphere recently militarily where I was the hunted as well as the hunter. Parts of Africa have the same radical Islamic issues, so I passed on that trip. I have a close friend that lives in Alaska, but out of state hunting is a bit pricey for my pay grade! The .375 is just a dang classic round, but I would love a .350 Norma to be honest. So little time and money...so many guns!

Hi Bird Dog II,

I didn't get any more info on the .35-300WM but it's not hard to sort a load if you got serious about it.

Like ShootersChoice7 and Con, I'm a known .35caloholic and have my share of .35 wildcats. I like the flexibility of using pistol bullets and lead bullets at appropriate velocities, as well as having the premium heavy bullets when needed.

My confession is that I also have a .375H&H and it's more flexible than most people think. I often hunt with it loaded with 264 grain Lyman cast gas check bullets at the same velocities as my .38-55 and it's just as easy to load Big Bore bullets of 200 grains weight, and replicate the .375 Winchester. If you want to get a funny reaction, walk into a gun shop and ask if they have any .375H&H cases, when they say yes and ask "how many do you want?" say 300 and watch what happens. Very funny...They're not used to that over here.

Good luck with what ever you choose.

Well with that line of thinking there is no need for 338's or 270's as long as we have a bunch of 30 cals, along with 22's as we have 17 cal and 243 cals. I could go on, but I guess you might see the point
