405 Winchester with a belt

https://lh3.googleusercontent.com/7r...w=w274-h600-nohttps://lh3.googleusercontent.com/ZQ...0=w184-h500-nohttps://lh3.googleusercontent.com/4h...Z=w385-h326-no
I take 9.3x66 case and run it thru my homemade belting dies and..........I end up with a 405 belted case that can be loaded with 405 dies
I also rebate the rim to .473".
Waiting on a Shilen Barrel.......and I also need to grind a reamer.
The case holds 78 grains of water.
I like the cut off 260 grain X bullet, but with deeper free bore I can load the 300 to a length of 2.530"
The ole Axis test gun is getting a work out!
Also working on a 444 Belted using a 9.3x62 case.

More pictures! More story!

It was late and I got confused.....again.
Hope this one makes sense.

I have the 06 mag ordered. Bought the shorter trigger guard. My 243 HB will soon be a long action.

https://lh3.googleusercontent.com/3k...T=w337-h600-no
The 405B mag is long enough to let me seat a 300 X out another band, making plenty of room for powder.
I just need to throat the bore deeper. Not sure about that, yet.
Shown with a 268X.
And,
The Shilen .411 barrel is being shipped, now I have to make the reamer.

The finish and die reamers are ground round. Just need to relieve the cutting flutes.

And either buy or make the pilot bushing. .252 pilot.

I did not make the belt step, I will cut that separate.

8 degree taper, .100 freebore ].313] and 1.1/2 degree throat. It is like having .200 freebore.

While I had the taper set, I decided to cut the die reamer also.

And the best part is, you can also shoot belted 06 brass.

This is so very cool! You are a DIY’er to look up to my friend!

More please!

[ UPDATE ]

Just ran a starting load thru the new chamber. Hodgdon calls for 55.0 of Varget at 2079 fps. with a 24" barrel. [starting load ]
I made a 23" barrel and got 2039 fps for my first test shot. [ Hornady 300 FP ]
So I am right on par with 405 Winchester load data.
Plastic stock and steel one pc. base weigh in at an even 7#s.

Sounds promising.

So what do belting dies look like.

I have wanted something like the .450 Marlin but fitting a std bolt face. Looks like these are close enough.

Just working up loads, 2393 fps with a 300 Hornady FP. Mild case Pressure, but starting to get some KICK!

Just shot a case full of Benchmark and a 270 Barnes TSX..............2569 fps.........just shy of 4000 ft #s of energy!

The factory plastic stock is still doing fine, but keeping an eye on it.

Now to mount a scope and do some group testing.

Should have the brake installed next week.

They are just tapered dies that reduce diameter .010 each [.007-.008]. Takes 2 dies, then the third one has a sharp edge to help seat in the belt.
Third die is used in an arbor press.
Then I finish them in a lathe.
All home made stuff.
CH4D use to make these, might contact them.

targets?

The lower shot was a scope adjustment, then fired the next three. 2545 FPS....300 TSX.

Both the 210 TSX and turned down Monoflex 208gr, will hit 3000 FPS!

That is a point blank range of 300 yds.

I have a high scope at 2".

Picture of the rifle. Factory stock is doing OK.
