How about a 300 Win Mag “Modified”?

It seems, there are, stupid questions.

One thing I love about the internet is the ability to research and evaluate tons of information and opinions. Notice I didnt say blindly follow others research and opinions.

I just bought my first 300 win mag this month and here is why.....

First, it is time tested. This cartridge has been vetted and it's a known quantity. Flat shooting and hard hitting.

Second, it's available. You can get cartridges and components in most places.

Third, versatility. This cartridge has a wide range of bullet types and weights available for it. It easy to reload for and there is tons data availabe

Drawbacks, or should I say points of discussion.... it is designed from an old case that headspaces off a belt (even though the 300 win mag does not), the neck is shorter than most, it burns powder, has stout recoil.

Honestly, this cartridge has been "improved" and redesigned so many times that you have oter .30 cal magnum options that will address your concerns.

It's really like buying an older cj5 vs a new jeep. Yes some of the old problems are no longer there, but both will get you there, one is alot easier to work on and has proven reliable in every weather. But....the new one is more comfy, has a better stereo and handles a bit better.

My opinion, buy a new rifle in one of the newer 30 cal magnums, compare and contrast our old 300 win mag, and report back to us!
 
300 WIN modified, why would you do that, when there are other 300 Magnums, specifically, what is being described as the 30 Nosler or 300 PRC etc. The short neck on 300 Win is a non issue! The belt, which is stoopid, on shouldered cartridges, is unnecessary.
 
how does shooting the same weight bullets at same speeds equate into out performing it!!??? :confused::confused::confused: I can do face thingy too! :D:D
So you are running a 225 grain ELD at 2800+ from a 24" 300WM? I would love to see a pressure trace read out on that.:eek:

The 300 PRC is doing it at 65K PSI.

...but let's jump all over Hornady for their marketing hype.
How's that .260 Rem run in an AR, by the way?


Actually, back when the 7 rem and the 300 Win mag was brought out. (1962 and 1963) Reloading was for match shooters and common distance for shots was less than 400 yards for most hunters. Most of them would buy a box of ammo and it would last for several years.

They had no interest in buying a complete loading setup and normally shot and ejected there cases one time. Saving brass and case life meant nothing to them, and the ease of feeding was the selling point.
Also for the time some factory loads would produce 1 to 1 1/2 MOA, and if you were lucky you could fins a factory load that could best 1/2 MOA.

There was/is an advantage to the belted case in strength in the case web area due to the added thickness of the belt, especially for the primer pockets longevity.

Now that we strive for better ammo, longer distances and better accuracy we have to re load. for those that still just hunt and don't re load a box of ammo every two or three years it is still a good idea, So for them, the fully sized belted cases are still a good idea.

Before the belted cases came along, it was common for the prudent hunter to try every loaded round in his chamber before going on a hunt, especially a dangerous game hunt. the belt solved this problem without dangerous amounts of head space.

Belted cases still have there place and the internet experts cant change that. There are many different designs for different uses, and if they are loaded and used as intended, they will give many years of excellent service and accuracy

To much effort finding the perfect set-up...

Grab hunting gear, fuel up truck and stop at grocery store to fill the kooler. Stop at gun store,,, buy gun and get them to attach optic... Buy ammo...

Drive to hunting grounds,,, sight in and go kill $4!+...

Its just that easy you know. Ha
 
I love the 300WM and have been shooting it for years. Gotta admit two things I don't like are the belt and the short neck. Any such thing or any way to eliminate the belt and lengthen the neck? I don't want to move up to the R.U.M. Because the WM burns enough powder as it is and supplies all the power and distance I want.

Set back i.e. cut back your barrel and rechamber to a 300 without belt but with longer neck...in your second reincarnation you might breakeven financially and in your third reincarnation, you would be money ahead...then there is your time without a rifle while it is at the gunsmith AND the time and expense of working up a new load. Find a real problem to solve and shoot a great round as is.
 
For a hand loader building a custom rifle the difference between the 300 PRC and 30 Nosler is academic at best. They are within a couple grains capacity and produce near identical velocities. The real difference between the cartridges is factory ammo and factory rifles.

30 Nosler - designed around hunting, essentially slightly faster .300 WM without the belt. Most factory rifles are limited to the same 3.4 COAL with 10 twist barrels as the WM while factory ammo offerings slightly improve the WM loads from 150's up to 210gr.

300 PRC - Designed around using the 210+ class .30 cal bullets for long range hunting and target shooting. Factory ammo is currently limited to only 210+ class bullets and factory rifles have 3.6 COAL and 8.5 twist.

So if your the custom and handload route flip a coin, if not evaluate the purpose of the rifle with the available options and decide accordingly.
