Yes I am now a member of the 10MM club as I just got one yesterday. Never thought I would own a Glock but I now own 2 of them. They are the aforementioned Glock 20 and a Glock 35. I guess my next purchase should be a Glock 17. A trifecta so to speak of Glock pistols.

You did well ! My M20 is my go to hiking
pistol. And my M29 is my bedside gun.

While I do love the S&W model 29 and own 2 of them I prefer my 4 inch model 58 as a bedside firearm. Its easier to move then my 8 3/8 inch model 29's.

Welcome to the 10mm club.....carry a Glock 20 as my EDC...have shot the 10mm since it's inception....if you want maximum performance from the 10mm, check out double tap ammo and Corbin....they load the 10mm to it's potential.

No! I meant "he typed CorBon, but auto correct put Corbin".

If you really want to tap 10mm full potential, get into hand loading. You can load down to puff balls and all the way up to the equal, or better in some cases, of the top end commercial fodder. All the time staying within published load data and pressure limits.

The 10mm is a hand loader's dream.

I agree on the reloading. We did 1400 rounds last June, 155 gr HP and 180gr truncated. Both just middle warm, and it's WAY hotter than any commercial plinking ammo. Load some medium hot, not even extreme and it's easily like Corbon, about like the Underwood ammo. I have not loaded any 10mm with maximum book charges. That would be pretty zippy.

Anyway I have a S&W 1006 and Glock 20. I love them both.

I bought a G20 a year ago and am still figuring out how to not shoot way under the target. I have let several people shoot it and they all shoot low with it. Doesn't matter what grains or maufacturer. Glock said they would take care of it. But I don't want to let loose of it until I get the groups a little tighter. Plus I am getting better gripping tighter. Never has jammed, I do love that.

Glock can send you the correct sight to adjust it, but you might have to measure or find if the current sights are marked with a number or letter, so that they have a reference. Any nearby Glock armorer or police armorer might have the sights in stock, also. A common service to correct police issue guns.

Funny your timing.

I bought my G20 in 99, sold it in 2005 and bought it back this week. After years of shoving nuclear 10mm's out of my 610 and my 1911 format 10mm's, I finally went back and got my 10mm G20 with the KKM extended barrel I put in it.

Just picked up a Delta Elite in 10mm last week. Have not had the chance to shoot it yet. It probably won't get carried a lot as I like my commander sized guns much better for that. I am trading some reloading equipment for 350 rounds of 10mm today so I might get to shoot it this week. I also have 2000 rounds of 10mm brass on order from Starline. Any recommendations on which powder to use would be great. I will start loading 180 grain XTP's and some 155 XTP's as well.

Best Powder I have found for 10mm is AA#9 for 180 and 200 grain XTPs and AA#7 for 155s. The powder meters very well.
I use them in a Delta and an S&W 1006 and 610. For mouse fart loads I use 175 grain LSWCs or 135 grain LRN and Win 231.

My those 610 are beautiful guns, my dream gun if timing of funds and availability ever meet, but my glocks will do nicely for now, I'm glad to see the popularity of the 10mm picking up, and for me since I can't reload in my present apt, underwood is all I buy although I would love some Winchester 175g silver tips I can't find them anyplace.

You carry the heavy gun and leave the lighter gun on the nightstand?

I'm plan to load my once fired 10 brass.
I'm going to shoot my G 20 for the first time Tuesday. The owners booklet recommends 200 rounds for break in.
I also have a Dan Wesson 1911 10mm Match. It is very accurate and fun to shoot. I was able to buy a 40 S&W barrel from DW. It was a drop in install and feeds the 40 cal reliably from the 10mm mag. I use it when 10mm ammo gets scarce.

As said above, welcome to 10mm. And it is a reloaders dream!

I had best results with 800x poser but it's a pain to meter. Switched to Longshot and am happy!

Save that brass!!!!!

I will give AA7 and AA9 a try. I have used them both before in other cartridges and I don't remember having any problem with metering. I got 350 rounds of various 10mm ammo including Starfire, Black Talon, Hornady, Blazer(aluminum case:() and some commercial reloads using Starline Brass and 180 XTP's. I hope to get to the range this week for a short session at least. The Delta is an awfully pretty gun as is but I plan on changing the back strap and adding one with a mag well. I will also be adding a new safety and ebony ranger cut grips.

"You carry the heavy gun and leave the lighter gun on the nightstand?"
Yep, the M29 came with night sights and the M20
has the lighter trigger and is more accurate. It works
for me. The weight difference is not noticeable.

What's an M20? And it must be a CHUNK if it weighs more than a model 29.

January 21, 2013, 01:14 PM
The m20 is the full sized 10mm about the same size and weightas the Glock21, althrough I've always used G20 or G21 instead of M20.

Ohhh ok. So I guess when he said m29 he didn't mean a big smith and wesson wheel gun.

I like the 10mm and have been loading it for a number of years. It's great to handload for, as others have stated, AA #7, #9, 800X and Longshot are very good powders for the 10, Blue Dot and Power Pistol are also popular. For AA #9 I prefer to use CCI magnum primers.

I have a G20 and G20 SF, both with aftermarket Lonewolf barrels, plus there's a 6" KKM barrel that speeds things up a bit. By summer time I expect to take delivery of a custom 1911 tactical longslide, it will get carry time at my place and on the trail.

Some things I've learned over the years is to load for the bullet and not for the caliber. It's very easy to load the 10mm to uber velocities, but it's more of a challenge to load for the bullet's sweet spot.

Not an upper end 10mm load, but obviously too fast for this 155gr Gold Dot;

http://i1103.photobucket.com/albums/g474/aztrekker511/10mm155GD1420fps007.jpg

This handloaded 165gr Gold Dot performed poorly out of a 40 S&W carbine, but I observed the same results three separate times in 400 Corbon, a ballistic twin of the 10mm in this bullet weight.

http://i1103.photobucket.com/albums/g474/aztrekker511/40cal165GD1500fps016.jpg

While these bullets were captured in water, Speer #14 confirmed later, redline for the JHPs is set at 1300fps. For those who are buying Underwood ammunition, I would strongly suggest you test that ammunition in your personal 10mm. I've destroyed a number of different JHPs at 10mm velocities.

http://i1103.photobucket.com/albums/g474/aztrekker511/10mm200WFNGC1200fps4inchsolidbone27water005-1.jpg

I like 180gr Gold Dots for JHP carry, but after seeing poor bullet performance in the 1300s, I load for 1265fps. At this lower velocity, which is actually rather fast, the 180gr Gold Dot pushes a lot of stuff out of the way when a lot of stuff gets in the way.

In 10mm, exceeding a bullet's sweet spot typically results in lower bullet performance and this will remain so until bullets are designed and constructed for 10mm velocities.

+1 There's just no substitute for good load development and using the bullet most appropriate for the task at hand.

2Z1, do you have an "after" picture of the bone or lead bullet?

I've wondered about the 165 Gold Dots, I've heard of mixed results with them. I have some lying around, but one looks different than the other, so I guess the 165gr GD has seen some slight design changes over the years.

I recently shot one of them into water too, with a muzzle velocity of 1400 fps from a 6" G24 and it held together, but could also tell it wouldn't have taken much more before coming apart. It also seems the more shallow cavity Gold Dots are better for higher velocity than the deeper 180gr GD.

Wasn't able to capture the WFN, not sure if there's enough water in Arizona to do that. :)

If you look closely at the bone joint, you can see the entrance point on the left and exit on the right.

Here's a closeup of the exit;

http://i1103.photobucket.com/albums/g474/aztrekker511/10mm200WFNGC1200fps4inchsolidbone27water009.jpg

Being curious as to the performance difference between the 200gr WFNGC and 200gr XTP (1220fps),the XTP totally fragged the bone;

http://i1103.photobucket.com/albums/g474/aztrekker511/10mm200XTPbone1220fps009.jpg

However, in doing so, the bullet never made it to the water bottles to be captured. These fragments are all of the bullet I could find;

http://i1103.photobucket.com/albums/g474/aztrekker511/10mm200XTPbone1220fps005.jpg

For my environment, the WFNs are the way to go for trail carry.

Oops. I should have noticed that strangely round hole on the left side of the bone. But, I'm a biochemist, not a radiologist! I only know how to make the bone dissolve. :)
