Just bought a Glock 20, and they only defensive rounds avaible were the Hornady 200 grain XTP at 1050 fps? Is this a good round for home/self defense?
 
The performance is almost exactly equal to 200gr .45ACP+P load, therefore suitable for use. The lower velocity makes it particularly good for HD. For better bullet expansion I would favor 155gr load for self defense outside a dwelling.

Thanks. I do like the idea of a subsonic load for indoor range and self defense use. These rounds seem similar to the 180 grain Hydra Shock.
 
If you have to shoot it indoors you will not even notice how loud it is. I was right next to a police officer when he fired three rounds from a .40 indoors......it sounded like pop, pop, pop.
 
Having a 10mm that is equal to a .45 load is a bit like getting a Corvette and turning off two of the pistons in the engine. The whole point of having a 10mm is to have a hotter, faster bullet.

Better yet is to have the versatility to load as needed. Just because a Corvette will do 150 mph doesn't mean you have to always drive it that fast.

This is a mild load, and not my 1st choice, but perfectly acceptable. One of the negatives of 10mm is limited ammo availability. Once ammo is located, stock up, or reload. Part of the beauty of 10mm is being able to shoot 135 gr bullets over 1500 fps, mid weights of around 155 @1400 fps or even some of the really hot stuff pushing 200 gr bullets over 1300 fps. Pick what you need as conditions change.
 
Do yourself a big favor and order online. Underwood Ammo is as good as it gets. Buffalo Bore & Double Tap are also good. If you're gonna own a 10mm (the alltime greatest handgun cartridge ever btw), shoot the good stuff. The ammo available in stores is marginally hotter than .40 S&W.
 
175 grain Silvertips run 1290 FPS (which is 50 FPS faster than the 175 grain 41 magnum Silvertip Mid range load) with tolerable recoil. They are older bullet technology yet still give decent performance and excellent accuracy. They are not difficult to find and reasonably priced.
 
The 200gr XTP is probably best left as a field bullet. For defense, I prefer the 180gr Gold Dot. It expands nicely but still holds together, even if driven 300fps faster than designed.
 
Thanks for the replies. I know all about the hot stuff from the smaller companies. I will use those for field use. I just want a a good, subsonic load for home defense.
 
Hey CraigC do you have a 10mm?
Two, sort of. I have a Ruger Buckeye .38-40/10mm convertible and a Uberti 1873 Deluxe Sporting Rifle, the first 10mm. I've been turning cannelures in .40/10mm bullets and testing them in the rifle. The 135gr Sierra at 1600fps makes a great varmint bomb!

I've always wanted a 6" 1911 in 10mm.
 
That loading will do fine, especially if thats all you have. Not a full on loading, BUT it is hotter than 40 SW you will normally find.

Gold dots are great, but they are tough to find now. The silver tips are tough to find too at a reasonable price. FWIW I use the 200g xtp in my 10mm when i am in the woods. Mine is running just under 1250 fps and it seems to work very well on deer. I think the 200g xtp is great as a compromise round for outdoors. If I carry my 10mm with that loading it is for animals and possibly people outdoors. I am not sure how it would perform at 1050 fps though…

The lighter 165ish, 150ish or even 135ish grain loadings can be very very fast and might be worth a look if you are concerned about over penetration.

Personally I would not worry about subsonic for indoors unless you are running suppressed. A supersonic round will tend to perform better most of the time since that bullet is designed to be supersonic. The sound of any "normal" round will not bother you if you need to use it.

If all you have for now is the 200g loading I would use it and not feel bad about it, but I would probably keep my eyes open for the lighter faster stuff to try out. That is the whole fun part of the 10mm, especially if you hand load.

Standard autopistol rounds such as the 9mm, .40, and .45 ACP are very much on the LOW side for the intended purpose of "stopping" an adult male human. The 10mm with REAL 10mm loads has the capacity to add something useful to the equation, however, the load you quoted it by no means a "10mm" level load...as another poster stated, it's a .45 ACP equivalent load.

Underwood makes THE BEST 10mm ammo available today at any price. For self-defense you simply do not need a 200 grain 10mm bullet, but Underwood makes 10mm loads in every conceivable weight.

I would suggest the 155-165 grain weight delivering 750-800 lb-ft of KE...which is what the 10mm was originally developed to do.

If all you want is .45 ACP power, then you didn't need the spend your hard earned money on a 10mm.
 
I've got a 6" KKM in my G20. The ammunition from the boutique companies, BB, DT, and UW, are top of the line for velocity performance and bullet variety, but the old 175 Silvertip is still a very good choice. It was specifically designed for the 10mm and is not a .40 S&W bullet loaded into a 10mm case. Somewhere there is a great thread with photos showing how much better the 175ST is on feral pigs than some of the HP bullets used by the boutique companies. For man or most beasts you would take on with a 10mm, the 175 Silvertip should be more than adequate. Where the boutique loadings excel is with heavy HC bullets with great penetration.
 
In the original .45ACP loads "silvertip" meant aluminum jacket. In 10mm loads, "silvertip" means copper jacket with nickel plating to simulate "silvertip" appearance.
Any so-called 10mm bullet being launched at speeds below 1,100 fps SHOULD be suspect...if you see a 180 grain "anything" going slower than 1,200 fps KNOW you are not getting all the power the round can deliver.
 
My main reason for subsonic for home defense for the blast/noise. Same reason I was always advised to use .38+P FBI loads instead of .357 125 loads for home defense.
 
If you have to shoot it indoors you will not even notice how loud it is. I was right next to a police officer when he fired three rounds from a .40 indoors......it sounded like pop, pop, pop.

What you "notice" is irrelevant to hearing loss. Also, you won't notice the difference in the sound of a subsonic or supersonic round, when fired indoors. A subsonic round will damage your hearing just like a supersonic round.

My nightstand piece is now a suppressed G17. I'm going to load up some 147 subsonics for this purpose.
 
Be careful of double tap ammo. The last 10mm rounds I sent through a chrono were 100fps below advertised velocity. Plus it was overpriced @$.85/round.


+1 on Underwood. Top notch company with a top notch product
