10mm all compatible powders load data

[Benchrst]

Something I've been working on the past few months: http://10mm-reloaded.com/

Mostly because I really enjoy the hobby, and to build a workup baseline for MY gun.

Some loads are below / above book values, some have no published data. What proves safe in MY gun may not in YOURS. Use the information linked in this post at your own risk!

It's also important to note that most loads were NOT tested (Gen 4 G20) with the stock barrel.

43 powders, 78 bullets, 811 loads

Thanks.  Very good data.

[The_Shadow]

Thank you!  The data is well laid out, good job...

[se3388]

Good job, I'm sure it got tedious doing that.

Thanks guys!

Tedious?  Not really. Once i had defined the spreadsheet format it became as easy as entering new loads, and then reporting reality after each chrono session.

OK, the brass pics are tedious!

[TSP45ACP]

Very nice.

Thank you.


Just out of curiosity, are lead bullet and plated bullet velocities close to the same with identical charge wgts?

Just out of curiosity, are lead bullet and plated bullet velocities close to the same with identical charge wgts?

Looking through the data at the 176 grain cast compared to the 180 grain plated, the case bullet was faster at a lower powder charge.  Makes sense.  Lead is included in babbit metal and in many alloys because it smooths operation and machining.

Looked at the chart , but is there one preferred powder to load 135gr HP up to 220gr RN -HP or cast ? And still work with all weights in between ?
I've done rifle loads and usually just just powder charges for said projos....never reloaded pistol before so does it work the same or do you need different powders per weight of slugs ?

[The_Shadow]

There are several that will work, LongShot has been used by many of the Commercial loaders from 125 gr up to 220 gr.
Blue Dot can be used across the spectrum but may not have the highest velocities, but very accurate in my experience.
If you are willing to take the time and hand weigh the IMR800X it will cover the spread quite well.
Accurate Arms AA#7 can cover the full range, but AA#9 runs out at the heavier projectiles.
Power Pistol has worked well but seems to pressure spike up with the heavier bullets, I see the BE-86 as being about the same as the bullet weights get heavy.
CFE Pistol and AutoComp will be usable but these too are faster powders so the heavier bullets don't get the shove for speeds.
Powders like 2400 are slower than Blue Dot and they run out of room being denser.
Unique, Universal and HS-6 can cover a good spectrum for target play.
The faster burning powders like bullseye, Red Dot, Herco, 231/hp38, AA#5 and a host of others can push a bullet for target with very small charges for the yield and make for target play at economical advantages.

Just recently I procured some BE-86 because of its yield across the board, and cartridges, while using less than some of the slower powders as a balance of performance vs. economical yield for a long haul or SHTF future. 

[Benchrst]

So far, if I had to pick one, I'd be #7.

[Sniper711]

I'll look into the Longshot or #7 then !
Like to stay with one powder if at all possible to avoid confusion ......when things got tight here a while back I bought whatever powders I could for my .223. & .308's  and wound up with about six different ones .....a pain to reset my powder setup every time I run out and have to swap brands 

[sqlbullet]

If I were going to pick one powder, I would pick Blue Dot, followed by Longshot.

Longshot will provide better velocities in 10mm, but Blue Dot has far more applicability in other loads.

[The_Shadow]

sqlbullet, I agree and Blue Dot has always been part of my on hand powders, handgun and shot shells, even as reduced rifle loads.  Accuracy and performance for the long haul!

Since BE-86 came out it too has a broad range of cartridges, so I placed it in my on hand supplies for the what if the SHTF.

However any of the powders I listed earlier could be utilized in several cartridges

[sqlbullet]

Agree 100%.  Blue Dot has just been around so long, it is hard to find a cartridge that doesn't have some kind of Blue Dot load data.  Event for large bottle neck cases there are cast bullet gallery loads and usually Blue Dot is right there.

Longshot was all I could find when powder was very short. I've grown to like it quite a lot. For .45ACP plinking loads, accuracy suffers, but hot loads and as noted 10mm, it's great. Probably I sound like a broken record, but it's my go to powder now (I have too much!!)
