Sweet 10MM goodness

Thanks for the reloading info
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.

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;
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.
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.

All is not lost, this was a 200gr WFNGC test, handloaded Double Tap bullet at DT velocities, 4" of solid cow leg bone, left to right;
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;
Being curious as to the performance difference between the 200gr WFNGC and 200gr XTP (1220fps),the XTP totally fragged the bone;
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;
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.
