POLL: SD Ammo For A Glock 29 (all stock)

[Overkill338]

I hear 135 and I think 9mm not 10mm. The 10 was designed around the concept of pushing 200 grain bullets at great speeds.

I think of the 135 in a 10mm like shooting a 110gr at a deer from a 30-378 Weatherby. The muzzle velocity will be super impressive, but all you're going to get is a nasty splash wound.

Just curious as to why no one considers the 135 grain in 10mm.  It seems it's ballistics are above the old 357 mag 125 grain ballistics and that has an awesome track record.  I have my 10s loaded with 135 grain and have one mag of 135 and another of 180 XTPs for backup.

I use the underwood 135gr for my G29, it is my EDC ammo, I do use 200gr hard cast and XTP's for woods carry in my G40, but for two legged targets the 135's are tough to beat. Very manageable recoil, 13 to 14 inches of penetration, massive wound channel. I personally prefer my EDC ammo not to penetrate much more than 13 inches.

I know this wasn't mentioned, but the Underwood 165 grain Gold Dot is a very manageable round. It might work out well in the G29.

Good luck with whatever you choose.

Thanks 4949. I'm waiting on Hornady to email me back with info on the 200 XTP. Ideal expansion window, suggested MV, and is it a good bullet for SD.

Some here like it. 
I can't  speak for everyone else but personal preference is to limit carry ammo to those that have been shown to penitrate a minimum of 12" in FBI spec ballistics gel,more preferrably with heavy clothing in front.  I've never seen a 10mm 135gr. projectile consistently do it.  YMMV, and not interested in starting another handgun hydrostatic shock debate. 

One guys opinion:  The 135gr. 10mm hit with a ton of energy but lack mass & sectional density to penitrate as deeply as My minimum. 

[sqlbullet]

The 125 grain 357 mag has a sectional density of .140.  The 135 10mm has an SD of only .121.  It doesn't penetrate nearly as well as the 125 grain 357.

A better comparison would be a 155 grain 10mm which has an SD of .138 and can be loaded to very similar ballistics.  The Underwood 155 gr XTP runs 1500 fps and would pretty much duplicate the 125 grain 357 mag load, but in a .400 bullet. 

The 135 grain 10mm is more like the 110 grain 357 loads.

The 155 XTP from Underwood seems like a great option actually.

T Glock the 155 grain XTP from Underwood is super hot. At least it was...I don't know if they changed it at all.

Intercooler might have an idea on this.

[Overkill338]

I've been doing a lot of thinking, and I think to be more responsible, until I get the beast tamed, and used to the recoil, I'm going to carry the Georgia Arms 180 Gold Dot. They've been chronoed at 1180ish from a stock Glock 29. After a few months of practicing with hot loads (my new friend at Underwood  says they are coming out with a new line of target ammo), then I'll move up to the UW 180 GD, 180 XTP or 200 XTP.

So do you guys think I'm being smart or overly cautious?

Just fired some Underwood 155xtp's today. First time shooting "full power" loads in my Delta Elite. Definitely more noticeable recoil(I really like it!!!) but wayyyy manageable. I need to find more creative targets than clay pigeons and gallon jugs. I guarantee they would put a hurting on 2 legged critters. 

[Overkill338]

Thank you Shogun! I've heard recoil is a lot more noticeable in a 1911 platform vs a Glock. Not having shot both, I have no idea. The 155 XTP might just be the perfect SD round.

[Overkill338]

Out of curiosity, I figured free recoil with a 29 and UW 180 GD & a 33 with UW 125 GD.
29 = 10.51 ft/lbs
33 = 9.28 ft/lbs

There isn't THAT much difference in what I'm already used to shooting.

I calculated the power factor for both and the G29 is around 216 and the G33 around 171(I subtracted 100 fps from both bullets).  10mm for the boom!

[Overkill338]

Very nice!

I just used the numbers off their site and not chrono numbers from each, so the free recoil would be less.
If you want to figure power factor for sure, Olgo got 1231 fps from a G29 with the UW 180.

I like the 135g. BUT... I carry the 10(G29) thru the winter months as its larger and bulkier than I can conceal in a t shirt of summer. (But I prefer the gun) So its also a time when heavier cloths are worn by bad guys too. Under these conditions, I fear over expansion and under penetration.

BUT, I have dusted a couple coyotes from my mec tec using Nosler 135s and BLUE DOT powder at 1600+ fps and I can tell you expansion is VIOLENT!

I like a 155g in the 40 (HOT) and 165g+ in the 10MM with the lion share for carry going to 175/180g and hunting going 200gs.
