Wow! Way to go el jeffe! Nobody needs to light a fire under you!!!!!!!
Now, was it tiggertate, that had an action itching for a bigbore?
First dude with a new 50 cal. Lots of fun potential!

WELL I AM AS HAPPY AS A KID WITH A NEW TOY!

awesome work jeffe!!!

jeffe...you forgat to add the quick load data on the 300 grainers

also can we paperpatch 500 s&w pistol bullets for plinking/economy???

i laughed pretty good when jeffe reffered to the 500 a.r. today as "a mean little bastard" when reffering to its potential performance with 600 gr woodleighs

yup...mean little bastard...

bastard of the rigby

with DaveC's information on the 600gr woodlieghs, I am going to revise and republish the 500AR drawing and speculations...


looks like it is going to be 2.65" and 135gr which will add ~60-75 FPS accross the board.

i'll get to that tonight, i guess

Sounds good, any extra case length will help me in the .375 length action I will be using!

how about a 2.5" and a 2.65" with the 2.65 just having a longer neck???

pick yer poison!

"mean little bastard" and "fat bastard"

so, if i get 2150 with a 600, I am running with a 500 NE in a 9.5# bolt gun, 92ft-lb recoil, and very low (for a bolt gun) pressures...

Looks good,

How does this round compare to the old .500 jeffery in terms of pressure with your "guesstimate" loads...

Or given the same bullets and velocity, which one has less pressure?

No boomy, everything moves forward. Same lenght neck.

o.k.

i am just a hair farmer doing air guitar in the basement and jeffe is eddie van halen ripping up the fretboard on stage

i still like the nicknames "Mean little bastard" and "fat bastard" but the working name 500 a.r. is still good

soooo it will be right on par with the 495 a2!

no belt or rebate big boomer economical big boomer

wes,
the 500 jeffe is 163gr, mine is going to be 125-135 gr.. i listed presures at an estimated 57500psi, quite a bit higher than the jeffe's 44k, but still not bolt sticking high pressures

jeffe

New 2.65" case

I dunno...

is it worth is for 5 grain to go to a 2.65 case? I know it's on the design stage, but I am not wild about it just yet.

jeffe,
Will you be building on an M17 action? I have 2 I'm contemplating what to do to. Interested in what your planning to do with the magazine boxes and how they're modified for the bigger case.
Cheers...
Con

Con,
yep, my first one will be a m17, and I haven't begun work on it yet, as I am still "figuringout" the design.

modifying them for a bigger case is goign to be about the same as making them work with a 416 rigby, except shorter, which is not a big deal.


i am not really really pleased with a 2.65 case.. so I am thinking on it

jeffe,
Many thanks for the info ... you've got me thinking about my sporterised Winchester M17 .
I'm still digesting the 2 pages of info ... but why in an effort to help you "figureitout", are you displeased with the 2.65" case length, and as boomy suggested have you considered 2.5". Perhaps ala beltless 460 A-Square short? I've pondered why that short case hasnt been 50'd before. Perhaps "AR" something around its length???
Cheers...
Con

although i think the 2.5" will have more actions to fit in and more appeal... i'll be happy either way.

a two canalure bullet is in order i think with the 2.5" case... you can load long but you cant load short if you get my drift. fwiw

the gain in capacity sn't all that great, and .100" doesn't SOUND like alot, until you try to stretch an action to feed milsurp bullets, and 3.9 OAL just MIGHT be possible (hard) but 4.0"" aint happening

I think i am going to go back to the 2.55 case.. I like 2.55 cases.. but I haven't made up my mind

jeffe

2.55

2.55 should be fine, I'm not looking for the most powder and velocity just a "soft" shooting 500 to go with my other big bores. I haven't ever read any complaints about the killing power of the 500 Nitro....

i dont think .510 600@2200 is "soft"

jeffe, go head with the 2.65" case. When shooting mil-surp bullets, a separte follower in the mag box for single shot loading makes more economical since to me. Than doing all of the extra mill work to go to 3.9" on the action.

Sounds like a coin toss is needed.

how about the longer shoulder and still a 2.55 case? that's a .410 neck, which fits the bullets, and a 3.35 oal, which will help with milsurps

in a rifle built for it, a 26" barrel and a 3.85 (CAN be done on an enfield) thats nearly 2200 FPS with 643 milsurps (2125 is FAR lower pressure).. FROM THE MAG

or 4.1" single feeds with hornady 750s at 2000 fps...

there's a long range plinker


jeffe

that would be interesting, kinda like a mini-unrebated 500 jeffe that is a do all cart.

but i dont think there are no flies on the reg 2.55" with the cal lenght neck.

i do like the 2.55" case length thing so it has the most appeal and even though you can put it in a m98 and not the best platform, it still will work. people put 500 jeffe's in them so this will be a better choice and no feeding issues.

you know i have to go there but you could do a 2.65" for a full length neck and just trim down to 2.55 for the uber multi purpose dg long range plinker

2.55" cal neck my vote but hey, you are the maestro

with MUCH thought and planning, I have decided on the 2.65 case...

and have ordred the reamer, gages, and die reamer!!

jeffe

verrry happy to see this move forward!
can you fill in the unwashed masses on the basis for the 2.65 decision over the 2.55?

i guessed you wanted to keep uniformity of length with the other a.r.'s...

i am guessing it will have a cal length neck...

soooo 495 a2 performance in a shorter beltless cart...perfection!

Boomy,
the 2.65 is the same length as the 550 express, and while an intermediate length, the OAL on the crimp is 3.35, and fits in the other actions.. I then kicked the can around about a .41 subcaliber neck, and said "nah"....

biggest bang, no downside, and PERHAPS even hornady brass, as well as jamison!!


stuff is on order... should be several times faster than bauska in delivery.. so about the same time.


put a cock on open and speed lock in the enfield... will wait till have a couple fireformed cases before I make the box

soooo headstamp brass and maybe a dare we dream factory round??? good going jeffe! please tell...

noo!!!!
hornady 416 rigby brass and perhaps jamison unheadstamped brass

oh,

Go Jeffe!!
I think you will be happier with the 2.65" case, let me know if you need a few more cases...got to do my part!

Rick,
thanks.. if i can't get jamison to make I run, I was going to hit you, rip, dave, and neal up for some

any revised case capacity for the 2.65" version???

Jeff,

Can you do a 50 AR on a Tikka action?

not an action i work with... i understand that a tikka action varies from a reworked nagant to something designed 3 year ago...

so, I have no data to make a projection
