10mm ammo

PLINKING.40 · 05-03-2012, 15:26

Hi Yall, I am looking to buy some 10mm bullets from underwood, and saw the Hot stuff at 1400-1600 fps,that I would use for maybe Zombies or Hoggs, but the lower 1250-1300fps for EDC, "Q".? is it going to be ok on the factory G20 barrel (little under supported) to shoot the high power stuff without getting a more supported barrel like KKM or such..would like to stay stock..was going to ge 50rd boxes for stock pile...

Hello!

I don't really understand your question. But will make a few comments that may ast some light on your decisions.

Generally speaking when looking at pistol ammo the higher velocity equates to lower penetration. This is because pistol bullets are more fragile and lack sectional density to provide deep penetration.
SO such vel will only be attained with the lightest bullets. These bullets will likely profuse horrific shallow wounds on "Zombies". The will not penetrate a much tougher hog adaquity you may well kill them, but I doubt you will recover them.

Pick a good bullet a proven bullet. Then be sure it functions and shoots accurately. Then practice with it and carry it.

For hunting I recommend the Hornady XTP in 180 or 200 loaded to 1300+ and 1200 respectively.

If hunting I would look hard at a good art mkt barrel then hand load it for optimal performance.

I thought that the hotter stuff in the 1600fps range was the harder hitting round, but mostly refering to the "smileys" bulge on the case end, don't want a KB out the back of the case and blow the mag and sides out. I was thinking the 135gr and the 185gr rounds..

Let's cut to the chase here...

ALL Underwood Ammo, (and anything else on the market today), is just fine shot through a stock G-20 barrel!!!!!!!1!!!1!!!

I'm sick of this dis-information coming up again.. and again... and again... and again...

FACK an aftermarket barrel, except for the most discriminating of re-loaders.

Clear enough?

The stock Glock barrel is fine.

Merrixs · 05-07-2012, 05:09

The bulge you are talking about with the stock barrel and factory ammo is just a bulge from the stock barrels generous chamber, it is not a smiley. Smileys are caused by over pressure rounds, not from the stock eat anything even when it's abused barrel. A smiley is a distinct grove in the case.

The stock barrel will safely shoot any factory loaded ammo, unless said ammo specifically states "fully supported". I think Swampfox was the only one to do that anyway.

Underwood has a caution on using his 1300 FPS ammo in Colt Delta Elites due to an unramped barrel. He has a 1200 FPS load for DE's. No such warning for other pistols.

A while ago I contacted Glock on this sort of issue. They stated very clearly that all factory ammo within 10mm spec is safe to shoot in all Glock 10mm pistols.

Yeah there is. No 200 gr. XTP in a G29. Get a lighter load, IIRC.

Is Underwood Ammo considered factory ammo?

it's a serious and as heavy a load as i'd recommend for the smaller pistol, as long as you've got some strength in you why don't you like it? my girlfriend even says these rounds aren't too strong!

PLINKING.40 · 05-07-2012, 14:52

Thanks Gents, I guess I will save $165 clams on not getting a KKM barrel, I just wanted to be safe on the fact that if I went Hog hunting with the hot stuff, I didn't have to worry about a BlowOut, from the case not being fully supported at the bottom...Kool.

No worries man, you, (and your Glock), will be fine.

I thought there was a disclaimer on one of the UA rounds that didn't recommend a G29.

I think that was Swampfox for the 29.

Underwood has a Delta Elite specific load.

yeah just for the 'Colt Delta" pistol, something about not having a ramp

i'm going to switch on my next order to the 180 grains, it's just the 200's weren't nearly as hurtful to the hand as i though (they where on sale!) so i felt i should stick up for them!

I never got my Swampfox. I ordered at the worst possible time.

Kevin emailed me and said those DE loads are loaded to about 1240fps instead of 1200. Still safe and still powerfull.

Cwlongshot · 05-08-2012, 04:09

There is another reason for the aft mkt barrel besides support... the extra length will get you some velocity and energy...

I have a KKM6" in route. Its going in my G20.

The Glock barrel MAY be fine and a safe, a better supported barrel WILL reduce wear and tear on brass simply because your not working it as much. Years ago I was shooting "race" guns in 38 stupid and you simply could not achieve "major" power factor with out a supported barrel. The simple fact that a barrel produced "smiles" shows its improperly supported. Unsafe, maybe maybe not. But a prudent loader will drop the powder, change the load or buy a better supported barrel.
I completely understand what post-apocalyptic, is saying. I also do not like misinformation. Or information thats mimicked because people continue to read other people posting about it. Yet have zero first hand experience with the topic. Its a bad situation and has led to some good products getting passed over.

Now will that barrel be as reliable? If shooting good loads I say yes.

People in general will always blame the equipment and them selves LAST. Even tho more times than not they have allot of "ownership" in those problems...

In my case, I wanted the longer barrel to get some extra performance first, better support in the chamber second.

If your just gonna buy factory offerings your really hamstringing the possible choices that are available to a hand loader...

Good luck,
CW

Nonsense. I load 200 grain XTP's with 7.9gr of Power Pistol and carry them in a G29SF. Absolutely no problems. KKM barrel and 23# Wolf spring.

swinokur · 05-08-2012, 11:06

The late Mike Wollard who owned Swampfox, did have a warning about using his 1400 FPS loads in a G29 IIRC. Underwood has no such warning for his ammo in a G29. He does have a specific DE load however.

PLINKING.40 · 05-16-2012, 10:59

I bought some 135g,165, & some 200gr speer & Nosler, ammo that are rated at 1300-1400 & 1600fps, is it still safe to stay with the stock factory spring, or bump up a lb. or so..

the OEM spring works perfectly with 200 Grain Underwood ( don't recommend going heavier then that).

I bought a Wolf Spring (19 lb) and it ruined my day of shooting, failed to load, failed to eject, stove piped, DO NOT change the spring poundage! (just FYI, they let me return the spring without difficulty)
