.416 Rem Mag: Information For Building A Budget Big-Game Rifle ( 416 Remington Magnum )

[Grumpy gumpy]

Something to be aware of, you need to watch the shoulder position of the cartridge, magazines often have a rib in them to stop the cartridge they were designed for moving forward, this may stop the longer shoulder position of the 416 from fitting in or interfere with feeding, they can be modified, but not always and it will depend upon your metal working skills

Thanks for the heads up

I will likely have a better understanding of your information once I get the Accurate-Mag bottom metal and magazine and can then do some basic test runs

Gumpy,

Did you happen to notice the screen capture that I uploaded several pictures back?
Its of the Accurate-Mag website where they listed their .338 Lapua Magazine.

There is a drop-down selection box for the options of "Overall Length"

The options to choose from are as follows:
1) 3.715
2) 3.775
3) 3.850

I dont know why there would be 3 choices of length unless maybe there is a common situation of manufactures or reloaders who use abnormal length and grain bullets which makes the rounds longer than the standard OAL for a .338 Lapua Magnum

Can you tell me what those choices would be for, and do you have any input on what choice is best for my particular situation of going to be trying to use that 338 Lapua Mag magazine for a 416 Rem Mag

The .338 Lapua Mag has an OAL of 3.68" and the .416 Rem Mag has an OAL of 3.6"

In case it helps somehow, I will upload again that Accurate-Mag website screen capture of the 338 Lapua Mag magazine and the 3 choices of overall length:

That would just be for people who custom load to the maximum length to suit the projectile chosen, and how the chamber is cut ( throat etc) Shortest would be factory loaded ammunition, in the picture that shows the mag from an angle you can see the groove I’m referring too, this forms a dent on the inside of the mag body to stop the ammunition moving forward, that is the bit that could cause issues, don’t know if it will without trying it, just something to think about.

The measurement in blue is the approximate position of the mag inside ridge to stop movement, the bit in red shows the rem case is smaller at the shoulder, but that measurement is 1/4 inch further forward on the rem case

Thanks for outlining that for me

I definitely see what you mean, and so for now I searched and found some close up images of the .338 Lapua magazine and trying to compare the .416 Rem Mag's bottle neck to the follower and feed lips to see if there's a likely problem with it not holding the 416 Rem Mag in a proper location.

So far I'm not see anything significant on the follower or feed lips but I'm not saying its not there... I know you're right about there likely being something that would need to hold the cartridge in position, but its just difficult to see more detail from the images of the 338 Lapua magazine.

Yeah, looks like I will just need to wait until next week when I can order the Accurate-Mag bottom metal and magazine, and then wait for it to get delivered to then do actual test runs to see how all the parts interacts with each other.

The following couple pictures are some of the best angles I could find to help show if there are any areas of the follower or feed lips that make direct interaction with the area of the bottle neck in the cartridge:

ORDER AND DELIVERY UPDATE: ACCURATE-MAG BOTTOM METAL AND MAGAZINE

On March 1st I place the order for the Savage bottom metal and 338 Lapua 3-round magazine, and I made CERTAIN to choose UPS for shipping even though it cost more to go with them.

Today I received the notification from Accurate-Mag that my order is processed and UPS is in possession of them.
Tracking is saying will be delivered this Thursday the 6th .... cool cool cooooool !

I also got the actions screws delivered,
and starting to look like the USPS LOST MY PACKAGE AGAIN !!!
The recoil lug been saying "In Transit To Next Destination" for the past 5 days!

Did anyone else also see Louis DeJoy (Postmaster General and Chief Executive Officer) of the USPS when he had to appear before congress 2 months ago?
He literally held his hands over his ears like a toddler, denied any incompetence, and blamed their extremely poor service on everything and everyone but himself and anyone else at the USPS

!!! DELIVERED YESTERDAY MARCH 7th !!!

ACCURATE-MAG'S SAVAGE LONG ACTION BOTTOM METAL, the 338 LAPUA MAGNUM MAGAZINE, and the ACTION BOLTS

So far I'm seeing very good prospects for the 338 Lapua magazine being adaptable to use the .416 Rem Mag rounds in it
Looking likely that it just needs some basic modification of the feed lips for helping to adjust the cartridge's angle whereby being held in a better position for when the bolt slides the cartridge forward to chamber it. I probably wont know more on the issue of how well the cartridge chambers until I receive the barrel.

The Accurate-Mag bottom metal is a DIRECT fit!
Very nice fitment all around the magazine well and the trigger guard.
I'm definitely impressed but for 185.00 it better be a direct fit without ANY need to remove material from the stock or bottom metal for it to make a very nice fit.

Was surprised when I opened the package from Accurate-Mag that the action screws came with it when had said in their descriptions the screws dont come with it.
The screws are 1/4" x 28 tpi (threads per inch) which are the National Fine Thread and were NOT made to proper length.
Accurate-Mag threw in extra long screws and the user is to then shorten them to proper length. I made the screw's length so their tip would clear no more than 1 thread from coming in contact with the action's bolt. This allows that additional space for if the torque specs should have me tighten the screws more and therefore the screws will still be short enough that they wont ever come in contact with the action's bolt.
The Savage action's screw holes for securing it to the stock are thru-holes (like many other manufacture's actions) whereby the drilled and tapped holes go straight through the action's rear tang and also straight through into the action's chamber where the mounting screws will directly hit the action's bolt if they're too long.
I provided the measurements for the front and rear action screws further down in the pictures.
