10mm loads for Delta Elite

[Notavictim646]

Hey Guys.

Looking to work up a load for my Delta. I plan to use Accurate #9 and 180 grain projectiles. Intend to run up to 1200 fps. Does anyone here have experience providing a steady diet for a Delta? What weights? Velocities? What do you think is a safe ceiling?

Thanks in advance,

Do you plan on reusing brass?

I wish I had some experience with which to help you, I'm just tagging this to monitor the responses for my own awareness.

Is your pistol an older model?

As in - the era of pistols that would crack the frame near the mag release?

I think the newer "re-released" once have bolstered frame strength in that zone.

I can't help you with your load development - other than to keep things mild if yours is an older pistol.

Hopefully shibumiseeker will see this thread and chime in. I know he's a big 10mm fan and reloads for it. And I THINK he has a DE.

I have an older Delta and it has a non ramped barrel, those loads you want to achieve sound find to me as I have had no issues with that weight in MY gun. I tend to keep my loads at 1200FPS for 180Gr and 1100FPS for 200Gr bullets. I know higher is possible but since these loads do what I need them to do (including hog hunting) I see no need to stress the shooter,brass,or gun. Let me know if you need anything else.

Tagging this for when I am back home tomorrow and can look up my loading data. I know of all my 10mms, my current generation CDE I don't fully trust with really hot loads because it has the least supported chamber out there in my entire collection. It handles my regular loads just fine but it really works the brass and brass life is reduced dramatically. I have 8 different models of production 10mms and a few custom built

Hey guys,

Answers to questions are it is a mid-90's "enhanced" pistol so it has the cutout. I do plan re-use brass, so any tips on what I might look for in my fired brass would be helpful. I am also full length sizing my used brass with a Lee Bulgebuster setup.

Thanks again for the help,

It's been my experience with MY delta that if you stay within published book molds you should be fine, just work up slowly and watch carefully for a bulge in the brass at the 6 o'clock position. I still feel there isn't a lot of need for the fire breathers in the ten mm. a 200gr WFN leans bullet at 1100 fps will do a lot of damage to even 350lb boars.

I shot a 10mm Gold Cup for several years in 50 ft. bullseye league. I started off at the very low end and worked up to a mid velocity range and found it to be the most accurate and comfortable to shoot. When I upped the charge to near the maximum I found it to be somewhat a waste and my score began to fall off. I did the same in .45 acp and .38. For me nothing is gained when pushing the upper limits of the charge in competition.

But 220gr hardcast at 1200fps does it better!

Do you shoot these loads from a Delta?

Do you shoot these loads from a Delta?

No, 3rd Gen S&W (1006/1066). I think the pressures of that load would be too high for a Delta.

Bump for some info? Shibumiseeker you out there?

Just got back from hiking in Morgan-Monroe for the weekend (where I was OCing my G29 on the hip stabilizer of my pack...).

My standard plinking round for all of my 10mm pistols is 8.5gr HS-6 under a 180gr Rainier Plated with a Wolf LPP.

I was heading out to the shack to do a little shooting, so give me a few minutes and I'll chrony them and see what they are running out of my G20, G20 Long slide 6.6", CDE, and RIA 1911-10mm.

 

[shibumiseeker]

So, 5 shots each, Chrony F1 12' from the muzzle, outside temp 80f, 500'ASL:

RIA 5"bbl= 1089fps, 1063-1111fps (48fps spread)
Colt 5"bbl= 1095fps. 1062-1123fps (61fps spread)
G20 Long slide, 6.6"lwd bbl= 1157fps, 1148-1172fps (34fps spread)
Stock G20 4.6" stock bbl=1022fps, 989-1056fps (67fps spread)

Clearly this load likes a longer barrel.

FWIW, I load 20 of these at a time and shoot them over a day or two then reload. I replace one piece of brass every 2-3 cycles now, so the average brass life is around 50 firings, this is consistent with my previous brass life tests I have published. All different manufacturers of brass, and almost always the failure mode is the base flattening and widening and getting too big to fit in the shellholder when I reload. I haven't tried using the CDE or RIA barrels exclusively to see if I get cracking as a failure mode.

My old plinking load was Power Pistol with the Rainier 180gr plated and I am trying to find my load data for that.

I use Power Pistol and 800x for my 180 and 200gr nuclear loads, but as they are above published data I am not going to post them.

Thanks Shibumiseeker! Just out of curiosity, What kind of recoils spring do you run in your 1911. Also, is the RIA 10mm bbl fully supported? Again, I plan to load my Business loads to about 1200 - 1250 with 180 grain XTP's.

Thanks again for Sharing,

 

[shibumiseeker]

I'm running stock springs on both 1911s. You shouldn't have any problems getting 1200fps, my HS-6 load is pretty mild which is why I get such long brass life. The RIA bbl is better supported than the CDE but not as well as the Glock.
