Really hot 10mm ammo?

That is a consideration, but I don't think as much of the recoil comes from the slide hitting the frame as we imagine. For instance a light load that doesn't fully cycle a gun still imparts a decent amount of recoil. Same with limp wristers wherein the whole gun moves rather than restraining the grip/frame enough to allow the slide to adequately move relative to the frame.

Watch high-quality slow motion video of a semi-automatic in recoil. The majority of the gun movement comes at/after the slide landing at the rear of the stroke.

Like I said, if you restrain it well, that is true. If not, not so much. Here is limp wrist videos of a Glock. It does get an extra kick when the slide reaches its maximum rearward travel (ie all of the momentum has been transferred to the gun as a whole), but as you'll see, the gun does plenty of recoiling prior to that. Pretty much exactly what I said in the prior post.

When one's life is on the line, it is apt to happen at night. There's nothing positive to gain by shooting a flamethrower round. It won't impress the person attacking you, for all he's thinking about is surviving too. You'll just blind yourself so your eyes can't adjust for a while . . . and that's never good to hear, or feel your attackers bullets while you can't see where they are or focus on your sights.

Ultimate velocity is, in itself, not much to desire either when it is life or death. I want a round which will allow me to control the firearm as fast as possible for accurate, follow up shots. Truly, you'll never know how the the recoil can twist your firearm out of its normal place in your grip until you are shooting fast strings against the clock and discover you suddenly can't hit the target because the gun changed a bit in your hand. Yes, the gun HAS to fit you properly . . . when firing a lot of rounds very fast.

Go to some serious handgun matches and watch who wins. Nothing beats speed and accuracy, and high velocity and muzzle flash contribute to neither. Certain rounds have a reputation for being able to get the job done extremely well with lower, more manageable type recoil characteristics. .45ACP is one of the very, very best in this regard.

I handgun hunt (deer and hogs) with a 6" S&W Model 29 .44 Magnum. My round is the 300 gn. Federal Castcore . . . but I wouldn't use it in a bowling pin match or a steel match.

10mm proved not best for most shooters in gunfights, it was too hot until loaded down to velocities of the .40S&W. I do know one S. Carolina trooper, a big man, who carried a Glock 20 on patrol and in LEO matches back "in the day," but that's very, very rare. I only could wonder how much faster and more accurate he'd have been with a Model 21 (same grip frame in .45 ACP).

Just food for thought!

The G21 is a smooth shooter, very controllable. I really like them.

I have wanted a G20 and also a .40 S&W conversion barrel for cheaper practice in the same gun.

The DoubleTap 200 gr hardcast is advertised at 1300 fps from G20. I have some and my chronograph showed 1315 fps from my Glock.

Curious about the year of manufacture for that DT ammo. Is it a recent batch?

Good old Winchester Silver tips come in at 649 ft-lb. Your chart seem a bit on the mild side.

Here are the 3 Buffalo Bore loads:


I got tired of playing the bullet lottery with Buffalo Bore (buy 3 boxes of the same load get 3 different bullets) and have switched to Underwood even though they are a little more mild.

While at local Cabelas I have seen 'Bear Load' by company called HSM. I have not looked at info on box but I would guess it should be rather powerful load.

However it got me wondering if there is a snappier/hotter round maybe a hollowpoint weighing less and moving faster? Like a 135 grain travelling at 1500 fps?

If you want to take it down that road you can get a 9x25 dillon barrel.
That is necked down 10mm brass shooting a 9mm bullet at high velocity.
If you reload you can get dies to make it yourself from 10mm brass.

It is really loud though, and the barrels don't last as long.
But it is basically what you want. You could easily put a 135 over 1500 FPS.
Or a 125 1700+ FPS
Better than the best defensive .357 magnum loads in a platform with less muzzle rise and felt recoil, and no cylinder gap.

The lighter you go the more it benefits from a longer barrel. With a 6" adding 100-300 FPS over around a 4" depending on how light you go.

A six inch barrel, helps get maximum power out of the cartridge, the glock 40 mos, does make a difference when shooting the full power loads.

My reloads with 14.6 gr of aa#9 with a 180 gr XTP out of a Glock 20 go about 1300 fps. It stopped a chipmunk last bear season.

I've settled on the 200 gr 10mms. I carry 200 gr XTP JHPs @ 1250 fps. The current load I am carrying is made by a co called Grizzly. I know there are others with similar loads. My dad loads me up 200 gr WNFP FMJs at the same velocity for practice, and I also carry these when I am packing in bear country. Testing in gel I have seen seems to indicate those XTPs deliver what I consider to be nearly ideal performance for a combination defense/medium game round, expanding to about .65 to .70 caliber and penetrating 16 inches or so. I love the 10mm Auto and am glad to see it has a decent fan base. It doesn't have a lot of commercial support, but it does have plenty of performance. My G20 is among the last of my possessions I would ever part with.
