I have the belt shoulder started and am
waiting for a die to hone out to swage the
bottom half of the case to the final
shape and dimensions. Hopefully be here
in a week or ten days.Ed

damn...its like waiting for christmas
thanks so much for you help in this endeavor

it seems empire rifles is delving into a belted 505...

we will need the 2.85" version to match the velocity

Got right die here and will have a
couple cases ready to photo in a week
or so. Was asked about making belted case
with just swages or sizing alone. It's not
the best as it kinks the inside corner of
case. My deal for making cases
doesn't kink the brass and cases are strong.
If everyone likes this concept and wants to do
a few guns I will recommend that they have Jamison
make a run of brass. Easier and cheaper than everyone
getting belt swage die sets to kink up cases.Ed

thanks for the update...
cant wait to see them

ed will post the pics but the best way to describe them is a scaled down 550 magnum and 550 express.
minimum taper but functional to get maximum diameter bullet on a belted case.

the 505's can be done on 375 ruger brass thanks to ed's expertise and the 510 would need to have brass manufactured at .555" belt dia and 540 casehead.

if 5 people join together and split a run of 1,000 pieces @ $1.50 a pop the 510 could get off the ground without any forming or headstamp issues. and it will have a decent taper.

thanks again to ed for his help

Boomie,
I'll be shooting the (at least fireforming) the 500 AR on the 21st

woo hoo! (in my best homer voice)

This is good stuff, Boom! It is a heck of an idea, strange it has not been done before! Will you still make that .470 AR, or go for this one, you own creation? You deserve this one!

the 470 ar is still happening...
glad you like it.

the 505 is doable today but the 510 needs to have brass made.

cant wait to see the pics from ed

Here is pics of case with 505 bullet.
Empty case second and a sectioned
case after belt put on and base swaged.
Case was expanded with expanders. It is
2.8" long. If expanded by fireforming
it would be .050" longer. Made from 375
RUM, belt is .546, base .532, mouth .526.
It has minimum taper, I like more.
It fits right in between 458 Lott and
550 mag.. Uses regular H&H bolt face, case
easier to get mag width built for. Works in
regular actions.Any action set up
for Rum cases will do. Get 535gr 505
slug out at 2150 easy.

To get more taper we got
another case to try and maybe 510 bore as bullets, barrels are easier to get.And
still work in RUM actions........Boom
has a wildcat.If it catches on its is easier
to have Jamison make run of brass.Ed

thanks ed!

the easiest over 50 bolt action to make! (gun wise) and with a run of brass even easier to shoot.

it is a scaled 550 magnum or 470 capstick!

ed...

what do you think the best name for this is?

505 capstick?
505 magnum?
505 me?

505 BUM ..
belted ultra mag!

You cannot call it magnum, as it is smaller than the already existing .505 Gibbs.
I went away from the Capstick, it just got confusing.
Don't be afraid to put your name on this baby, Boom!
It is a helluva round, .500 on H&H casehead, delivering .500NE ballistics!

But that belted, straight cases should be the vouge this summer.......!!!

505 bum...
belted ultra micro?

LOL.. just playing boomie...

well if we do the .555" casehead/belt to get the .510" it will be a new case and not be a rum anymore...the thing is it would require $2,000 in tooling...i know to some that aint much

what should i call the new case???? megamag? bolted nitro/express?

soooooo until i am wealthy the 505 and .500" will have to do. the cool thing about the .500" is cheap plinking like the 450's and using 45-70 bullets also with the ability to swage down 505 bullets. the .500 can come in up to 700 grains from ranger rick in alaska.

the next step is making the lazzeroni brass to size for the .510" prototype.

anyone got a few 416 meteor cases?

so then do you still need a belt to do .500 pills?

yes...the 500 on off the shelf rum brass can be done today...we need true spec brass to do the 510 and the 505 can be done but minimal taper but spec brass is best.

Yes you'd need a belt, as it would have
only .011" taper with .500 cal bullets.
A better taper than .505 with .006"
total taper on both sides. Maybe we need to
get someone to make heavier .500 cal dangerous game slugs of 500 gr. May be easier than
trying to get special cases. The 395 experiment has found some bullet makers. Jamison is not going to get to any wildcats or small non
government orders for couple years
it looks like. Ed

having .500 bullets made is easy...

flat nose solids in the lathe...

swaging down 505's

the .500 barrels can be had already.

someone offered to make some .500 bullets already.

hornady makes 500 grain .500 bullets.

redo the canalure...

500 grain .500" bullets s.d. is .286

spewed out at 2200 fps these might be fun

Boom After the last couple weeks I figure
the .500 is the way to go. Jamison
is tied up with gov contracts he couldn't do
my order with him for another year, and
it started two years ago.So if you get a run
.500 big bullets made send me some and
round up a few more 375 Rum, and I will get
you a few made. Ed

i think a 505 to 500 swage die would be the cheapest/easiest route...

since this is not a nostalgia round we can make it up any way we like.

temporary we could re canalure the 500 grain .500 bullets and lathe turn some solids down.

maybe a custom mold for some cast bullets we could lob 600 grains out at 2150+ would be good.

what design for cast ed? round nose? flat nose and make them hard cast?

there are some awesome bulletsmiths here.

I see the .500 cal 500 gr on net for
37 bucks for 50. Good price and has cannalure
and you can add extra cannalure. I with my
spinner lathe and others with
cannalure tool can do 50 in 20 min.And they
are ok for load developement, practice,
deer, hogs, etc. In these times of great
pain in ass of getting things done,
that's the way to go, using .500 slugs
at a decent price and using 375 Run case.
Most(95%) guys won't need heavy jacketed
bullets anyway for uses I listed above.
If you cast takes a lot of equip. And should be hardened, More equipment, Better at 75 cents
to buy .500 jacketed an put on cannalure
or use as they are. They will take 2200
easy. Ed

ed...i have 5 more 375 rum pieces left. should i send them?

Yes please send them. and find yourself box
of the 500gr .500cal cannalured slugs.
I will get them belted and straightened out,
to go with others here. Get you started.
I'll get reamer dimensions finalized for you.
You just got to do a gun.Ed

i will send them and i have a source for more if he wants to make himself be known?

ranger rick from alaska casts bullets in 600 and even 700 grains.

i will see about getting some samples from rick.

http://www.lsstuff.com/ranger-rick/

here is the 600 grain bullet...

use the top grease groove as a canalure.


he has an awesome web site full of good stuff!!!

Boomie,
call CH4D and ask them how much for a belt forming die for rum cases... i htink it's only about 200 bucks... well, it will be a set of dies, but you know what i mean.

$200-$250

after looking at the Pac Nor site, what twist for those 600gr flatties would you shoot? 12" or 18"?

ps...he paid it a great compliment too...

he said he had not seen a wildcat that he liked as much since the 458 socom...i hope he didnt diss the a.r. carts

great guy... we ended up talking for 2 hours about all kinds of things. his 45 years in the biz will help out for shure. he wants me to send him a cross sectioned piece and a few extra to try it out.

i would do a 12 but jeffe would say 18

actualy i would get whatever you liked and kept it a secret since all the twist war wounds have not all healed here

dave said
"so tell me, why in the h### are you using rum brass?"

"its big, cheap, and available everyday"

"good enough"

600gr .500 bullets? 18 would be fine, as that's no works no better than a 500ne with 570gr, based off length.. but it is user choice

jeffe

The swages if they can make the cases
properly would be real timesaver. And anyone
can do it that way if they are making cases.I could send him the 5 I have now
one being sectioned, 3 fully formed
and one with belt and not expanded.
This should be enough pieces
to let him make swages. Now the ones
he can make with swages may be slightly different than mine for size, so we wouldn't
determine reamer size until then. If we did this
I wouldn't need the other 375 rum but just send
Dave the 5 I have. If swages make case right
it would be 20 times faster and worth
the money..Ed

he wanted to play with it a bit but said he could not guarantee the outcome due to all the unforseen issues of putting a belt on a case that he never put a belt on before. he thought the lathe would be the best former and the dies to act as a finisher but that is still a lot of work. knowing the process of how the brass will be formed and taking the repeatable brass for the specs is key. i cant order dies just yet but for it to be repeatable and uniform i see that diea or having a swage die or having brass made (300 for $500 at qual cart) is the best way forward.

any input?

Tht's the way I do it- Start belt step
on lathe/spinner, and swage to final
shape. If Quality can do them for less
than 2 bucks each that's best way. ed.

I have 24 about to go in the mail tomorrow morning to your place Boomer. Do you still need them if we are going to go with Qual Cart? With only 5 in hand I figure you guys might destroy a few making a prototype to send to them. I would not mind paying $1.66 apiece, but like I had mentioned if we can -easily- swage a belt I could go that way too. whatever works, let me know.

Tim

Well, looks like I am along for the ride. I happen to have a donor rifle waiting for a new barrel. Ed you should have a PM or two.
