OFFICIAL: 10mm recipe thread

[UberMCoupe]

I'm interested to hear about your favorite 10mm reload recipe.
Powder type, bullet type, bullet weight, powder measure, OAL, fps, etc.
Are these match recipes or "plinking" recipes?

What's worked? What hasn't? Have you successfully pushed passed published data?

I'm interested to hear your set up, successes and learning opportunity experiences.

[Turo]

Sure, I'll play.

My favorite load so far is a 180gr fmj or jhp over 9.8gr of Longshot, with new Starline brass and CCI LPP No. 300.
I get an average of 1260 fps out of my stock glock 20sf barrel and when I tested them, the extreme spread was only 6 fps out of 5 rounds.


Be advised, this is above Hodgdon's maximum listed load, so be careful and work up to it if you're going to try it.

[Glenn H]

Shooting cast lead 155 gr SWC over 9.9 grains of HS-6 in Starline brass with WW LP primers.  That is my IPSC load.  I've also had some success with 180 gr FMJ over 8.2 gr HS-6 in the same brass.

[Taterhead]

All of the usual disclaimers apply here. If you chose to work up to this load, please reduce to 12.0 grains and work up on 0.2 grain increments. This load exceeds currently-published load data. Accurate used to publish a max load for a 200 TMJ of 13.5 grains, and Speer had a max of 14.0 when they still produced a 200 grain TMJ. This load data falls in between the two. This is a hardcast bullet so cast lead data is not applicable. There are no indications of excessive pressures in my setup. Of course things run differently in different rigs, so please work up carefully.

This is a hard-hitting load for the wilderness that cycles fine in my Gen 3 G20 with stock barrel and RSA.

Bullet: Double Tap 200 gr WFNGC hardcast
Primer: CCI 350
Brass: Starline
Powder: 13.8 grains Accurate no. 9
COL: 1.26"
Average velocities (not corrected to the muzzle): 1205 fps; 645 lb/ft ME

This load is pretty devastating on anything you shoot with it. It will blast through at least 7 water-filled gallon milk jugs and keep going. I recently shot it through a 2x4, a leather work glove, and 4 layers of denim. I only had 5 water-filled gallon jugs behind it. It cleared all five and was not recovered. It causes noticeably more damage than a 200 gr XTP at a similar velocity.

I sent a sample to a contact in Louisiana who shot a nice feral hog. Complete pass through with substantial trauma.

Now for a range load:

I have recently discovered PowerBond plated bullets. They are a substantially superior product to typical plated bullets like Berry's. The "jacket" is thicker, and they seem to be of overall consistent quality. If you cobble together a few guys to do a group buy, substantial cost savings are possible. I bought my last batch for $100/1000 with my local club group buy. Reach out to Matt@powerbondbullets.com for info.

Unlike Berry's, PowerBond does not call for the typical reductions in charge weights vis-a-vis jacketed bullets. They act more like a jacketed bullet than a plated. Please do not substitute Berry's or Rainier bullets for this data.

Normally, plated bullets require "kid gloves" treatment when reloading or groups get nasty. Also I have not been able to get Berry's to group well beyond about 1050 fps. No such problems with PB. I loaded them just like I would any jacketed bullet. No problems.

This is a medium-warm load that has proven to be a good every-day range load.  I also run it in IDPA with a definite handicap in power factor. It is nice and loud, so the SOs don't love it. 

Firearm: Glock 20 with stock barrel & RSA
Bullet: PowerBond 180 gr FP "copper bonded"        powerbondbullets.com
Primer: CCI 300
Brass: Starline
Powder: Accurate no. 9, 13.5 grains.
COL: 1.25"
Average velocities: 1175 fps

Outstanding groups. 10 shots within 1.5 inches @ 15 yards is pretty good for me. I could never get that consistent with Berry's, so for the same price, the PB bullets are a no-brainer.

EDIT: Substituting 9.8 grains of Alliant Blue Dot (all other data constant) gives a noticeably softer-shooting, nice-grouping load too. Velocities for the Blue Dot load are about 1110 fps. I tried LongShot, but have not found a charge weight that groups as well as A9 and Blue Dot.

[Taterhead]

Oh heck, why not post another favorite...

Firearm: Gen 3 Glock 20 with stock barrel and RSA

Bullet: Hornady 200 gr HP/XTP
Brass: Starline
Primer: WLP
Powder: 13.0 grains Accurate no. 9
COL: 1.26"
Average velocities (ten shots not corrected to the muzzle): 1200 fps

Outstanding groups. No problems cycling the Big 20.

This data lands between the maximum from Accurate Powders (12.5 grains) and Hornady (13.2).  This was safe in my firearm. Please reduce this load to 11.0 grains and work up in 0.2 grain increments.

Over at GT you were doing a primer comparison with the CCI 300 & CCI 350 with Accurate powders and I am curious as to the details with AA # 9. My loads with AA #9 (14.0 gr w/ 180 XTP, CCI 3000 and average 1,190fps out of a completely stock G20sf) have seem to burn a little dirty. Did you notice any difference with the CCI 350 vs the CCI 300 as far as a cleaner burn? I have a batch of test loads ready with the CCI 350's but have not had a chance test them. I am a little concerned about about a pressure spike also.

I did for the 155 XTPs. My results are posted in the Accurate sticky. The standard primer runs a bit slower (as expected), but the brass looks way less taxed at the top charge weights.  The temps were lower so that is part of the reduction in velocity. The Belgian-made A9 was more temp sensitive than current lots.

As far as cleanliness, I have not noticed much, if any, difference. Accurate seems to burn clean in that it leaves almost no soot. It does leave some tiny yellow flecks here and there though.

Accurate switched manufacturers a while back. The made in USA lots might be a bit sootier than the older Belgian lots from what I have seen initially, but nothing like other powders. My testing of 180 XTPs with CCI 300 primers yielded 1215 fps @ 13.9 and 1225 @ 14.1.

I have used CCI 300s, CCI 350s, and WLPs. The mag primers seem to speed up the burn speed of the powder a bit. I think the most important thing with Accurate no. 9 is good neck tension and high bullet pull.  200 XTPs actually run faster than 180 XTPs for comparable charge weights in my testing. I attribute this to high bullet pull of the long bearing surface of the 200 grain XTP allowing the slow-burning A9 powder to build up a head of steam.

No harm in trying mag primers (or in-between WLPs). I would reduce at least a grain and re-work up if you do so.

I posted this in a new thread as well, but I am hoping for some input and feedback on this one. My goal was to replicate the original Norma loadings as well as the current Buffalo Bore loads for the 10mm. I have no intentions of re using the brass on these loads, nor of using them a lot. Just a nice true 10mm power level carry  and hunting load. I am using 180gr Gold DOts, new Starline brass, WW primers, and AA#9. I started with 14.0 grains and worked up in .2gr increments but stopped at 14.8 which was the highest powder charge I could find in any manual (Accurate's old manual, for a 190gr bullet)

At 14.6 gr I had exceelent accuracy, and a SD of only 11FPS. velocity measure 1375 average from the 5 inch bbl of my Colt Delta Elite. 14.8 grains still showed no indications of high pressure like smiley faced brass but also yielded no more velocity so I have settled on the 14.6 load. The 80 I just loaded up will likely last me te rest of my life and then some as other than some function testing I do not plan to use them unless there is a crisi looming i.e. legitimate self defense although I amy try to shoot a deer with that load once as well. Those of you who load and shoot the 10mm a lot, what do you say about this load and my methodology. I am an old hand a rifle cartridge loading but a newbie in the world of high pressure semi auto cartridge loading. THANKS! Mark

Not sure why you'd toss the brass after one with those loads.  I do at least that, and get 10 or more from the brass.  If you have no indications of overpressure, there's no reason to not reuse it.  If you're still concerned, use them for low power target loads.

That's pretty fast for Gold Dots.  Too fast.  Maybe go to XTP or hard cast for more than 1200-1250.  GD's just go splat at that speed. They're designed for .40 S&W.  Overspeed, and the terminal performance falls flat.  They fly straight and have excellent performance, until they hit something.  I wouldn't use them for hunting anything bigger than a coyote.  Great for 2-legged critters.  Certainly not deer.

[sqlbullet]

I am conservative.  New brass for max loads, then it gets used for practice loads until it splits or gets lost.  But I certainly don't toss brass unless/until it is split.

[loadedround]

My info has been posted in the reoading blog.

I disagree 100%.  Not too fast...they don't just go "splat"...their terminal performance is great...they're great for Whitetail Deer.  Look at it this way;  10mm 135gr Nosler bullet loads, at higher speeds yet, have demonstrated plausible results in Whitetail Deer hunting.  To suggest a heavier yet Gold Dot at even less velocity wouldn't makes no sense.  My completely unscientific backyard testing with 10mm 155gr Gold Dot loads at ~1350 fps also support the idea of them being a perfectly acceptable for a Whitetail Deer hunting load.  Not looking for an arguement, just my own thoughts and findings.

It depends on your desired results for terminal performance.  Overdriving the GD's doesn't provide ideal terminal performance, according to common accepted standards.  That doesn't mean it can't or won't provide your desired result.  By "splat", I mean they expand much too early, and decelerate very quickly, while shedding mass.  This is not a Nosler bullet.  Different design and terminal performance at comparable velocities.  Comparing bullets of different design and weight provides data showing how different they perform.  Once a bullet is applied outside of its ideal velocity, intended use, design, or target selection, you rely too much on conditions you don't control, and luck.

I don't see anything wrong with the load, per se. If there is one quibble, I would say that any load that I would want to depend on has been tested in volume in my setup. All my mags. Slow fire, rapid fire, etc. I want to know that a round will cycle when it counts. Sometimes hotter loads have ways of finding ways to trip up an auto-loader.
