You have to pay good money to see the sacred scrolls at Ammoguide or go here for free (metric):

http://www.municion.org/

yeah, 4bore.. MM and I and rob, and ed put our data in ammoguide .. its less than 2 bucks a month, and comes with load data.

so, you can pay 20 bucks a year for ammoguide and suppport a great american ... or not

Maybe I spoke out of turn on that account. Good hand loading data with a name to stand behind it should be worth 20 bucks. I know I have about 10x that amount in current Hornady, Norma, Barnes manuals.

Great american, that I dont know. But free enterprise thats fine with me too. More than fine, that is the american way.

I would think dimensions drawings for any ctg what is now a std or hopes to be one some day should be out in the public domain (free). IMHO. I have found some SAAMI and all CIP drawings on line. I printed and bound the entire CIP rifle ctg library. (thanks to an AR posting) And now, this Spanish site is pretty good, errors and all, with photos and drawings.

Jack, I assume you got what you needed from Ammoguide. Thanks Jeffe. Bear in mind I am getting ready to change the case some. I am moving the shoulder forward, shorten the neck to .350 inches. In it's current most bullets are seated just above the little ghost shoulder, this produces a slight bulge there, don't hurt anything, does not cause an issue, I just don't like the way it looks, I hate bulges. So moving the shoulder forward, shorten the neck, puts the base of the bullet just below the shoulder, no bulge. I have a new reamer ordered, should be done in a couple of weeks or so now.

Yeah forbore, ammoguide is pretty decent site, not too costly and gives us all a really good place to post loads, drawings, and keep up with development of other things. It's a fairly popular site for that. I don't know as much about Mike Haas as Jeffe does, but he sure seems like a stand up guy to me, and very involved in all the shooting sports. It also gives us all a great reference to go to, just like for Jack here. In fact that is how Jeffe found me and brought me over to AR, or more like I followed him over here. I am sure he may regret that now!

As soon as the new reamer gets in for the 500 MDM I have 3 Win M70s in 300 RUM waiting to be converted to 500 MDM rifles. I have 3 Accurate Innovations stocks in the works right now for them. This cartridge requires one of these stocks with the aluminum chassis to keep from busting it. At least the most simple way to solve that issue for me.

May I ask if the .500 MDM is still using the
fairly heavy 550 grain bullet? Or, with the
penetration ability of the flat tip bullets like
CEB #13, are you going down to 500 grain weight?
Based on the 510 grain weight in the .510"
diameter 500 Nitro Express as detailed in the NEW
EXPLORATION thread, I thought 500 grainers in the
500 MDM was a reasonable idea! Thanks again.

DR, Michael determined there was zero need for the 550gr FN Solid for elephant because of the penetration of the 500gr FN Solid - so the 500gr has become the elephant standard bullet for the 500 MDM.

HI DR....

Cap is correct, there is just zero need for the 550s. The 500 MDM was designed before the BBW#13 and the new Nose Profile North Forks. But even then, I was getting incredible penetration with a bullet that JD and I worked on, which was basically the same or near same profile as a Barnes FN. I was getting 7-8 ft of penetration with a 50 B&M and a 510 gr on elephant at 2050 fps in 2007.

The 500 gr #13 has already proven itself in the field numerous times on elephant, buffalo, and hippo out of 500 MDM and 50 B&M.

I have also been working with a 450 #13 and 450 North Fork, and would go to the field for elephant, buffalo, hippo, any day with either of those in 500 MDM or 50 B&M, with zero concerns.

As for the 510 gr .510 at 2200 +....... The penetration is there, there can be no concerns with it.

Michael

Thank you Capo and Michael.

Stunning that 450 grainers at .500" diameter do the
job at .2471 sectional density! Truly amazing what
the technological advances have done regarding the
need for .300 sectional density and higher with older
bullet designs. Science is WONDERFUL!

If this is applied to the romantic favorite 577 NE, it
means a 600 grain weight bullet at 2200 - 2300 FPS
MV is as good or better than the origional old British
ammo with 750 grainers!!!!!

Pretty much says it all...

So what is this about changing the specs on MY rifle cartridge!? Are you just trying to spend all of my money by making me get a new barrel and dies and start over You are killing me here! How am i going to pay for all those extra animals this sept? Not too mention explain to wifey how my new super power rifle needs rebuilt? I hope you have extra room in the bat cave?

So where do I send my rifle is it going to go faster??

Brent.

NO NO... No changes.... Those were done in late 2009.....

HEH HEH.....

ALWAYS PLENTY OF ROOM FOR YOU IN THE BAT CAVE...... Especially when you come with Apple Pie!!!!!

I find myself having to "Ration" my remaining supply, and becoming someone concerned about your next visit? HEH HEH....... As you know, I have become rather spoiled on the Apple Pie....

Hmmmmm.... Maybe I should change the specs, taking everything into consideration?

Ahhhh, maybe you luck out, I am now thinking 500 B&M, 2.5 inch version.. Rifle is finished, sending for stock, and waiting for Hornady Dies... Which are very slow coming I am afraid. 500 B&M? Something I am playing with, full nose projection NonCons, tips added, load in magazine.... Something like our 458 B&M SA that is IN THE WORKS as we speak....

Oh yes, there we go, shouldn't be too long before that 458 BMSA is ready, maybe I don't have to ration so much of my Apple Pie as I thought! HEH.........

Michael

Michael if your 500 B&M arrives before your dies you can always short stroke you 50 B&M dies to begin load development...

Cap

I already played with the 50 dies, problem is, the RUM brass at 2.5 is a bit thinner than it is at 2.25, so it won't quite grip the bullet..... I have a few other .500 dies, I will probably try to see if I can get the top end tight enough, but no go right now.

You know this, but when Apple Pie is concerned, my priorities will not be with pink stocks..... There will be a lot of B&M guys out there Elephant and buffalo hunting with "Pink Rifles"..... HEH HEH.....

Do 500 S&W dies work? Answer is nope... Perhaps the 500 Martin but where'd you get dies for that one?
