now if iam shooting the 10mm loads like the 165 grain gold dot out of the g-29 can i expect a little less expansion and a little more penitration? is that the norm?

coltrane679 · 01-27-2005, 01:01

Good stuff, Mike!

Quick question--are you still planning some .450SMC (aka .45 Super) loads? They would be sweet out of my S&W 625.

agtman · 01-27-2005, 10:26

Mike: GREAT information and a big "thank you" for all the time and work you put into producing it! ;c

T***10mm: I'd ask that this thread get a sticky pronto, since it contains answers to penetration & expansion questions that get asked regularly here and on Caliber Corner about Double Tap Ammo, in particular the 10mm loads.

Plus, because Mike used the scientifically-accepted test media for developing the penetration & expansion data on DT 10mm ammo, it secondarily provides valid documentation pertaining to the issue of "overpenetration" when using DT's full-power 10mm HPs - those specifically designed and intended for defensive use against human assailants (i.e., the Nosler, Golden Saber and Gold Dot HP loads).

Thanks again, Mike!

***MCNETT*** · 01-27-2005, 11:42

From a G29 the 165gr GSHP went 15.0" and showed expansion to .84" The petals were folded further back on the bullet fired from the G20.

Excellent! ;f

hollow10mm · 01-27-2005, 16:06

so would the 165 GD expand to like 1.0 and penitrate a little farther out of a g-29? i think iam gonna have to go with 165 GD.

i vote for sticky as everyone always wants this info.

a1b2c3 · 01-27-2005, 16:16

Information much appreciated. Those results are better than I expected and why I carry your 10mm ammo on-duty.

maximum · 01-27-2005, 17:10

Mike, do you have any penetration results for the 200 gr BTB @1400 FPS?

Brasso · 01-27-2005, 18:11

I hope all the .45 is King crowd doesn't see this. There might be a DT 10mm ammo shortage.;f

hollow10mm · 01-27-2005, 20:25

the 230 grain GD out performs all minimum requirments for Hand gun cartridges for S/D it more than doubles its size and penitrates 3.25 inches past what is considered "atequite". with that being said iam going to use 165 grain GD in my g-29 it will expand to 1.0 and penitrate 15.5 inches, but it takes a LITTLE longer to open up out of a g-29 compared to g-20

bac1023 · 01-27-2005, 21:26

This data is the reason I carry the 135gr load. It should deposit most or all of its energy in the BG without overpenetration.

i'll second that question!

mark77418 · 01-28-2005, 09:37

These results are very impressive. The 200 grain XTP penetrated 19.5 inches. I think that is what I will use for carrying in the woods in my G20. Do you guys think that would be a good choice or do you think the 180 grain gold dot is better?

I use the 200 grain XTP with 13.0 grains of AA#9. Average velocity is 1113 with s=7.3. I gave trying to get to 1200fps for various reasons. Pressures were getting to the edge. If I need more power the 44 Mag is pressed into service.

I'm with you brother - thats what I'm packing right now too! ^c

hollow10mm · 01-28-2005, 13:16

go with the xtp.

Chainsaw Maniac · 01-28-2005, 23:59

In the woods? XTP for sure. McNett recommends it for animals up to 400 pounds. Gold Dot opens up too quickly as a hunting round.

Steve A · 01-29-2005, 07:19

Any pics?

sparky315 · 01-29-2005, 15:23

Excellent, Mike! Are those .45 loadings standard pressure? I've never been a fan of bullets lighter than 230, but I might have to switch from the Ranger T to your 200-grain GD load.

Never mind on the pressure question, I looked at some other threads and found the answer.

PaleGreenHorse · 01-30-2005, 04:03

All this Gello talk should have made this thread "Sticky" by now. ^c

frank4570 · 01-30-2005, 07:14

How are you guys getting 1400fps with a 200gr lead bullet. Is it simply because it is lead instead of jacketed? Is this a normal velocity for the doubletap ammo?

Sabot 23 · 01-30-2005, 14:23

I would also like to see this thread stickied. Great-to-know info!

One surprizing detail, though: 165gr GD has better expansion than the 155gr load? Is this due to the petals peeling back farther on the 155s? Is it possible that at some point in the bullet's travel through the gelatine the 155gr GD actually had a greater expanded diameter, and then as it continued through the petals peeled back farther, in effect reducing thr final expanded diameter?

Or, to put it another way, is it possible that the 155gr loading may actually cut a broader wound channel and permanent cavity than the 165gr GD, at least through a portion of the "target". Do we know anything about the "wound channels" carved out by these loadings?

It seems to me that everyone should have a mag loaded with the 135gr and/or 155gr loads for inorganic barrier penetration, and a mag loaded with the 155gr and/or the 165gr loads for flesh and bone penetration. Or just have three mags handy, one with each load. The 10mm is truly the most versatile of all auto-pistol cartridges - awesome! Thanks again, McNett!!!;f

**Tazz10m** · 01-30-2005, 15:26

Hey... so i'm a little slow......;g

Btw, MCNETT ROCKS!!!

***MCNETT*** · 02-01-2005, 00:06

Yes, the 155gr petals were "peeled back" further than the 165gr load.
-Mike
The 200gr BTB travels at 1300fps from a G20. It penetrates 25" in pine boards.
