10mm powders?

Registered Users do not see the above ad.

So, I picked up a Colt Delta Elite.
I am looking to try and achieve something like what Double Tap and Buffalo Bore are doing with their 200gr hard cast loads. Kind of a 'woods' load.
Also, I would like to load some jacketed RNFP at more modest velocities. Maybe 180gr around 1000fps? Basically want a 10mm 'special' load, I'm still looking in to it. These are for practice, and are the bulk of what I want to run through this gun.

I will not ask for specific loads. Just, what powders are you guys liking for 10mm? Both heavy and light loads?
I've got Bluedot on hand, but I'll buy something else if needed. Both Hodgdon and Alliant powders or readily available locally, at reasonable prices. So my preference goes to them.


For a bonus question...it looks like a Wolfe 24# recoil spring is a good idea for the hard cast loads. Would my proposed practice load cycle with that? Or, am I going to be swapping springs for loads?

For 180 grainers around 1000 I've used unique with good enough results that I've not looked for another load. 2400 is what I used for the hotter loads although I saw similar loads with blue dot. I have yet to try the 200 grainers in mine so have no experience to share. My 10mm is a Glock 20 but have enjoyed the round enough that I would like to find one in a 1911, congrats on a good gun!

Bad idea. Specialized springs are made for specialized uses in specialized guns. Such springs work great in competition guns that shoot one load only. For all around use the factory springs are best. The more special parts that are added to any gun the more limited in use it becomes. I have tried every spring combo known to man and have concluded that the only one who benefits is the parts seller. Save your money.

Blue dot will work for heavy loads and Bullseye, Power Pistol, or Unique should handle the light stuff.

Blue dot or AA#7 have worked well for me in full power loads.

I have used WW231 and Bullseye with the Lyman 401638 for my target loads.

My favorite is Blue Dot, and I've had some real success with it and lighter jacketed bullets. 135s over a no where near max load of around eleven and a half will do close to 1250- accurate and not jumpy.

I've used Blue dot with the 200 grain Beartooth, and the starting load gets 1000 fps. I've punched the charge up some from there, although I have not chronographed the new lot yet. I'd be tickled plum to death with 1100 fps, and I'd say that its pretty close.

These bullets function well, although care has to be exercised to make sure the COAL is very fine and specific, there is not a huge margin for error length wise. I've found them to be reliable, on average just the odd stoppage here and there, although I tend to load just a few at a time for a hog/ bear backup, or similar field duty.

Buy Beartooth.

Experience is a hard teacher, because she gives the test first, and the lesson afterwards.

Thanks everybody.

JBledsoe, I was under the impresion that for the heavy loads (200gr @ 1300-1400fps), a 22-24# recoil spring will keep the gun from tearing itself up. I'm willing to swap springs, to suit the load, to save wear and tear. I suppose my target velocity for this load is a bit more modest at 1200fps. Of course accuracy and feed/function will dictate the final outcome. I do appreciate your advice, I would like to keep it simple. It would be better to have one configuration to handle all loads.

Kind of makes me appreciate revolvers a little more.

Do any of you have any experience loading for the Delta?

I'll look into Bullseye, PowerPistol and Unique, for lighter loads.

What bullet weight are you guys liking for light loads? I assume jacketed is the way to go? I think there's some 155gr Oregon Trail hard cast locally at a decent price.

Thanks again!

How long has Colt been making auto loading pistols? Do you think that Colt does not know what springs work best? Think about it.

JBledsoe, you've got a point. For what it's worth somebody already replaced the original guide rod with a full length stainless one. I have no idea of the spring weight?
I've been reading up on it, the original dual springs equaled 23#.
Some people like the 22-24# single springs. But they may cause more harm than good, by pushing the slide forward with too much force.
Some people are running a 20# variable. That kind of makes sense to me.
I can use a buffer for practice, and I don't want to run alot of heavy loads.

Right now I'm going to apologize, this thread is veering away from reloading, fast. Maybe I should start a new thread pertaining to springs. What area would be appropriate?

I shoot two powders, Blue Dot for heavy loads and 231 lighter loads. 12gr's of Blue Dot behind 165gr golden sabers gives me 1270 fps from a Glock barrel and 1,420 fps from 6" Lone Wolf barrel. I use 11.4 grains of Blue Dot behind 180 grain Golden Sabers, don't remember the velocity but it has a whole lot more than 1,000 fps.

Shave a little velocity off the 165 grain bullets with 231 and they make a little more accurate load. I use a 40 S&W Lone Wolf barrel for most of my practice with 135 grain bullets and the 231 works great with those.

Oh, and I also use a heavier springs for heavy loads. I have springs from 12 - 24 pounds for my Glock 20. Just be extremely carefull about going lighter than the factory spring, the slide may not fully lock up and you can have a bad experisence when fired.

Mine loved Blue Dot in the light weights. And The midweight stuff(180 or less) I LOVED 800X

Blue Dot and AA7 for most loads. Raw power almost demands 800x.
38 Super and the 38/44. Two great rounds still today.

I've used AA-5, 7, 9, for 98% of the loads I run through mine. It meters great and it gets top end velocities with good accuracy. The 135-155 use the faster powders and the 165-180 get AA-7, then 180 - 200's use the #9.

Recoil is not bad with any of them and they can be taylored to get very accurate loads.

Ok, so I looked around, narrowed it down to 800X, Blue Dot, and AA#9. I know there are others but, these best fit my criteria.
Then I got some info from powder and bullet companies.
800X wins for velocity but, meters poorly. I can't buy it 'off the shelf' locally. That's important to me, so it's out.
Blue Dot and AA#9 both are readily available locally for the same price. They both have similar velocities and are comperable in regards to metering. Both are close in economy, as in loads per pound. However, AA#9 has a little lower pressures. Plus Accurate has better load data available. As do various bullet makers using Accurate powders.
Quite frankly, Alliant was my first choice. Their website stinks, they won't respond to e-mails, I had to wait 6 weeks to get a load manual,and unless you want to load Gold Dots they have no load data I can use.

So going ahead with AA#9. I've got 500ea of new Starline brass on the way. As well as 200rea of BTB 200 gr WFNGC and 500ea of Bear Creek's 200gr moly coated wide nose, all via my LGS.

Are you guys liking CCI (not magnum) Primers for AA#9?

Alright if any body cares...
I'm using WLP primers (not magnum), Starline brass, Bear Creek Supply 200gr TC moly bullets, and Accurate #9.
I've worked up to the max load listed in Accurate's load manual. No signs of pressure, flawless function, NO lead or moly fouling, and is more accurate than I can shoot. I really like #9, it meters perfectly and burns clean.
I want to work up the powder charge some more but I'm going to wait until I can get access to a chrono. I'll also start checking accuracey from a rest before I go any further.

Unless there is a compensator or muzzle weight, a full-length recoil rod makes as much sense as a bicycle for a fish.
Almost all I have shot in my Deltas are cast lead bullets, as-cast and hand lubed.
Best is to shoot your gun and determine what loads you like. Get a box or two of factory ammo (if you can find any) and use that to compare recoil. Then you can think about changing recoil spring to fit the load. I sometimes paint the recoil spring weight on the slide so I know what is in the gun.
In general, you probably won't want or need to shoot near max loads.
I quite enjoy shooting 155-180 gn bullets at whatever load makes my Delta Elites happy, and I haven't changed a spring yet.
If you don't want to batter the gun, don't load hot.
The gun can handle a fair amount of pressure, just not for every shot.
5.3 grains of W231 or 8.6 grains of Power Pistol and a 180 grain FMJ.
9.5 grains of Longshot and 180 grain JHP.
Longshot and AA9 are accurate and versatile.

I like the full length guide rod. It certainly makes spring weight selection easier, given Wolff's available variety. My gunsmith, who is excellent and I trust by the way, recommends FLG's.

I'm working this load up as a woods/hunting/dangerous game load.
I shoot the same components with the minimum data listed in Accurate's manual. This gives me an easy shooting practice load.
Quite frankly, the maximum load shoots pretty easy, on me, on the gun, and on the brass and primers.
I may just leave well enough alone and stick with the published data.

My gunsmith has done some work to 'tune' this gun to handle heavy loads. Including a EGW flat firing pin stop, appropriate springs, and I am still working on finding the best balance for a recoil spring. I'll try a 22# next time I go out. I want my recoil spring just strong enough to keep my slide from slamming back to hard. That way it will minimize how fast it returns forward. I'm also using shock buff's for practice.

Lot's of bases to cover here congrats on the Delta.

I shoot a 4.25" Dan Wesson and use a 22# recoil spring with the standard FPS, but I don't push the gun. I shoot quite a bit of mild loads and I find this spring # will work well with either. If I was expecting to shoot heavy loads only I pop in a 24#. I also run Wolf XP springs in my mags to catch up with the slide.

I've been using Double Taps 200 grain WFNGC with 8.1 grains of 800x, I don't know the velocity yet, but I'm guessing it's 1050 fps or so. With a 5" barrel you could get that bullet closer to 1200 fps, and that's about the limit to expect. 1300-1400 fps ain't gonna safely happen. I load them to 1.255" in new brass and they run fine.

I use CCI-300's, 350's have been reported to give erratic results with several powders in 10mm.

I have some of Beartooths bullets on the way now and plan to work my way back up and maybe even push it to 8.3 grains, but that's about it for me and my gun. I'm hoping to get close to 1100 fps.

For a mild load check out Accurate Arms 3.5 Edition for 170-185 grain hard cast bullets and AA#7, I've been shooting these for years with about 9.0 grains of AA7 which is the start load, I'm guessing velocity to be about 900 fps. Accurate, cheap, and can shoot them all day with the 22# spring. Point of impact just doesn't seem to vary much in the 10mm, with either screaming fast 135's or slow 180's or fast 200's.

I do intend to try some Unique in the future and reduce bullet weight even more. I'm looking to mimic a 9mm with a mild load and a 135 grain bullet.

As far as dangerous game, I've been carrying the 10mm for almost 20 years in the Central Rockies, but I don't think of it as any more capable then a 180-200 grain H.C .357 from a 4" revolver, my opinion is that the .357 and 10mm are essentially ballistic twins. The 1911 is a quicker reload and has other personal benefits over the revolver, I like the flat 1911 and SA trigger.

Under 500 pounds I carry the 10mm, over 500 pounds it's a 4" .44 Magnum and I think 500 pounds is really pushing it for a .357 or 10mm.

Jitterbug, I've found that WLP primers work great. Plus it's what Accurate lists with their data.
I haven't had a problem with my magazine springs. All (6) are factory Colt's, one used, five new.

I agree with your comparison between .357mag & 10mm. I know alot of people say the 10mm is closer to the .41mag. I think if you push it hard enough, it kind of gets close to low end .41mag loads. But, at the expense of tearing up the gun.
That being said, I like shooting and packing the Delta better. I also shoot it better. Mainly though, I just like it, better.

I agree with your 500# theory for dangerous game. I would still rather, and usually do, have a rifle or shotgun with me.
