50 ae primer

[sharp tooth]

So i reload s&w 500 and 50 ae and a quite a few others I kind of mucked up a bit when I was slamming in primers I used Cci 250 in my 50 ae brass …… because that’s what I used previously in the 500 which it uses.
Now large pistol magnums/ large rifle magnums aside I can only find 2 differences and that’s cup thickness and oal large rifle being slightly taller yes?
I used w296 so of course I use magnum either way the load data is
27.8-33.8 grains with a 300 grain xtp bullet “Hornady 8th edition” with a LARGE PISTOL PRIMER!
I loaded Cci 250 30.5 grain w296 and the 300 grain xtp
The primer actually sits just inside the pocket it’s not quite level and definitely does not protrude. Is there going to be different burn rates for Cci 250 vs the Cci 350? Could this be safe given I did not get these loaded max?
Lack of data for this cartridge stresses me out but it’s very fun to shoot also very expensive for factory loads.

Anyone?

 

[AJC1]

A primer swap is normally around a 5000 psi deal. If your not within that limit of max I would not be overly worried.

Anyone?

I have no experience with what you propose.
I am glad I caught this thread, because I have similar questions about this.
A similar thread that may be of interest to you can be found here, Federal Primers and Their Softness.

If I were in your situation, if the primers are truly set below flush, I would try it. That is a lower charge than I use for the same weight bullets, though mine are softer plated than the jacketed XTP.
Be certain they are flush! I just watched a full auto Eagle video. Not an experience I want to have, even on purpose!

In my own situation, I didn’t even think of using rifle primers!
I didn’t even measure to see if they would!
I even have some to try!

Leave it to me to find the most expensive and complicated way to try and solve a problem.
I ordered some 50Beowulf to cut down to maximum chamber depth in my 50AE Desert Eagle.

May I ask what brand cases you are using?
All mine are Starline.


I wish I could be more help. It must suffice that you have helped me immensely! Thank you!

Half the cases are nickel half are brass not sure off the top my head what brand. I’d likely load one round pop it off and mix one round with one of my previous rounds just so if it did slam fire it won’t try to empty the mag just for curiosity when I do get to reload more what’s your powder charge/ bullet

 

[Demi-human]

just for curiosity when I do get to reload more what’s your powder charge/ bullet

A just over Hornady maximum, yet worked up to and safe in my pistol only, 34 grain load of H-110 and a Berry’s 300grain, but loaded longer than book COAL.

Magazine length is my limiter for COAL in my generously cut chamber.

I have lucked into a few hundred Rainier 335 grain plated hollow points. These I am just working on now.

I am interested in your findings when you get a chance to shoot them.

 

[sharp tooth]

So brass is imi or Hornady and nickel is speer I did get a side picture of brass so you can see the primers aren’t really sticking out.

 

[Blue68f100]

The only real way to check is run a straight edge over the base. If you feel anything it's high. I see several that look high from the last photo. Another quick test is set the round on a hard flat surface and see if it rocks, only good for the really bad ones. The straight edge is the only real way to check that fast.

not that I know a lot, but curious on how full the case is with 30.5 gr of W296?

Not so full that another three and a half grains won’t fit fit in mine.

You use 34 grains of h110 in your 50ae?? My manual says max in the red is 33.7 anything past that is probably over reaching no?

I loaded some 50AE for a 6" Desert Eagle. I used Magnum primers with a stiff load of H110/W296 under a Hornady 300 grain XTP. I forget the grains of powder offhand... but I did chrono a shot and it went 1424 fps. I was up near the max, so I don't think you have anything to worry about. Have gone through about 100 rounds without issue... except it likes ejecting the brass right into my face.... which seems to be a common issue with these guns. lol

You know or remember the fps but can't recall the charge?
Check your notes , inquiring minds want to know!

I loaded them a couple years ago... and blew up the occasional milk jug or 2L with the kids... but never bothered to velocity test. They ran great, and never showed any signs of pressure. It was only a few weeks ago that I was testing some 300BO, and decided to take the Desert Eagle. I ran three rounds of 50AE, and it averaged around 1400 fps... a couple just below 1400, and the 1424.

Alright... Definitely magnum primers and I'm pretty sure the charge was 33 grains of H110/W296. At 30.5 grains, you're well under anything that will cause issue. One guy here said he was at 34 grains.

My 50th edition Lyman Reloading Handbook uses a 6" Desert Eagle for their tests with a CCI 350 Magnum primer, 300 grain Hornady XTP bullets and a Speer case loaded to 1.580" OAL. The velocities shown vary from 1284 fps with 29.7 grains to 1398 fps with 33.0 grains... which agrees with what I got. You're WELL into the safe zone, regardless of your primer choice. Time to add a little more heat!

Good Luck!

PS... You mentioned 500 primers... The Lyman manual lists CCI #200 Large Rifle primers in Starline cases for it's 500 S&W load data.

[n2omike]

Well you said berrys 300 grain which typically 33.7 is limit and past that is dangerous. But your using a different bullet completely View attachment 1082438

I did not say Berrys... I indicated Hornady 300 grain XTP... which are part number 50101... Same as the original poster.
My Lyman manual only went up to 33.0 grains... which is what I used. Your data shows 33.7 grains for the same bullet. At 30.5 grains, he is WELL below any pressure issues, regardless of primer choice.

 

[Demi-human]

So, after reading my post, and all its caveats about my pistol being mine, you think three tenths of a grain in a case load of thirty four grains is in dangerous overload territory, @C4AJ?
Please, explain.

Yup!

My bad I thought you were the other person and you weren't didn't realize it until abit ago.

Going off of my manual it warns to not go past 33.7. knowing how h110 is why I asked isn't that risking it? Was more of a question then a saying don't do that

 

[Demi-human]

Was more of a question

Gotcha.

Because of my larger chamber and longer seating depth, as well as softer bullets, my chronograph showed it took more powder to make the same pressure.

As well as good testing procedures and loading practices to be sure to stay safe at elevated temperatures. (I only make book speed in the summer with that load.) Or even at cold temperatures, as the inverse temperature reactive Silhouette is.

I always start low and work up. Only two haven’t found a nice spot below maximum, out of many.

It’s not really entirely true that reduced loads of H110/W296 in large cases is always dangerous. Reduced loads are less efficient and less predictable. That’s the danger; unpredictability. The thing you really don’t want is for the powder burn cycle to transition from deflagration to detonation.

Thing is, he's not in the 'reduced' load category. He's within the recommended range.

Sorry been busy kids wife work life…. So bottom line is it should be good to go. Check primers 1 was slightly dinged from seating maybe and maybe 1-2 others seated a hair above flush I may try to single shot those. Also taking notes to slowly up my charge rates however this gun is not extremely fun to shoot hot loads out of no need to push the 34 grains….
As for the few comments regarding the s&w 500 yes it calls for large rifle primers however everyone says use mag primers with h110/w296 so that’s my reason on that topic.
