Ran some over the chrono yesterday and got less than impressive numbers. All rounds were between 1190 and 1255 out of a Glock 40. I thought this was supposed to be one of the warmer plinking rounds available. Maybe they changed the load recently? |

Quote HistoryQuoted: What was the temperature there in CO when you were testing? Sounds like you were at least close to their published numbers. I read on another forum where there might have been a load change. Seems the older ones with the black trays were hotter than the newer ones in yellow trays. Maybe I was overestimating this load. I was hoping to be close to 1300 fps with the longer G40 barrel. I won't buy it again given the premium over other FMJ ammo. If only 10mm brass was cheaper I would just buy brass. |

You probably already know, but most "cheap" plinking 10mm is way less than even 1,200 fps for a 180 grain load. |

I thought this was supposed to be one of the warmer plinking rounds available. Maybe they changed the load recently? Its an overall absurd situation; people buy 10mm because it's an Magnum Auto cartridge....and the factory loads them all to .40 S&W power levels. It would be like if manufacturers started loading .357 Magnum to 9mm +P velocity ie 125gr @ 1200fps from a 4". But thats what they're done to 10mm. In terms of SIG, their FMJ is actually slightly hotter then their JHP defensive ammo....adding to the absurdity. 
Ironically, the only load approaching full power 10mm is the 180gr JSP from Federal...which doesn't expand. As a basis of comparison, Underwood 40 s&w launches a 180gr Gold Dot at 1100fps from a G22. And thats a within SAAMI load, not a +p. My buddy was launching 180's at 1150-1200 from his G34 with handloads based on Quickload.

What chrono were you using and what was the configured distance for the measurement? Even with a Labradar you could have that velocity reading coming down range 10y+.
With all of my chrono testing I try to measure against a benchmark firearm and benchmark ammo to get a better understanding of everything in relation to one another on that particular day. |

Most .357 mag 158 grain loads are 1,250ish fps from a 6" barrel. That's FAR below what the caliber is capable of. The 158 grain Buffalo Boar clocked 1,530 fps from my 6" GP100, and I have no doubt hand loaders could get more than that. Now I'm not saying all .357 mag or 10mm ammo should be loaded to max, but it would be nice if someone made a 10mm load with a 180 grain load at 1,300 and a .357 mag load with a 158 grain at something like 1,450 fps for cheap (or maybe just a slight premium). Right now if you want that performance (or more) from either you're going to spend $1/round from Buffalo Boar or similar. |

This is the exact reason I don't own a 10mm firearm- I'm not a hand loader. With some exceptions, if you're buying 10mm ammo from WalMart (I guess this analogy doesn't work anymore) you're buying ammo that's at .40 S&W velocities, or so close it doesn't matter.

Whereas there isn't a single 10mm big box defensive JHP approaching real 10mm speed. |

Quote HistoryQuoted: I feel like .357 is a little better, in that the 125gr defensive loads are still hot (Remington SJHP 125gr is 1450-1470 from a 4," Gold Dot 125 is 1400+). Whereas there isn't a single 10mm big box defensive JHP approaching real 10mm speed. |

I have found the Sig 10mm stuff to be a very fun target round. It's not a fucking artillery shell, but the recoil and noise lets you know it's not .40 S&W. It's very satisfactory.

Quote HistoryQuoted:
I bet that's because of two main reasons. First, they're loading the 10mm with bullets that were designed for .40 S&W velocities. Second, you don't need to push a 180 grain bullet to 1,400 fps to get good performance on two-legged animals. A 180 grain bullet at 950-1050 fps is perfect for the FBI and IWBA protocols on handgun performance. Quote HistoryQuoted:

Whereas there isn't a single 10mm big box defensive JHP approaching real 10mm speed. Right or wrong, if anyone is carrying 10mm for defense, its purely for more power then .40 S&W offers. To carry a thicker, heavier 10mm loaded with .40 equivalent loads would be insane. This is the performance of .40 HST from a 3.4" G27 subcompact: 
Ideal defense load for a 10mm would be a 158gr JHP (same sectional density as a 125gr .357) loaded to 1400fps / 688 ftlbs. |

A 180 grain bullet at 950-1050 fps is perfect for the FBI and IWBA protocols on handgun performance. I remember reading about the development of the 10mm back in the early 80's. The original load was the Norma 200gr going 1200fps (so the OP's 180 going around 1220 is in the ballpark) |

An off the shelf 10mm load of 180gr @1220 fps is decent. It's a good shooting load. If you want more go nuclear handloads or boutique manufacturer.

5 shot string 10MM XDM 10 5.25” barrel
Speer 180 TMJ bullet- jacketed, not plated. 1184 1207 1193 1178 1198 Avg: 1192 St dev: 11.42 This is a 90 percent load (7.7 Gr) straight from Alliants website for Be-86 powder out of my Springfield Armory XDM-10 5.25” The listed velocity for the 8.5 grain charge is 1265, I’ll post the top load (8.5 or less) when I run it. |

My SIG Elite 180gr data, out of XDm OSP (5.3”)
Last string over LabRadar: Highest: 1239 Lowest: 1213 AVG: 1224 ES: 26 SD: 10 Meh. Hoping to handload 200s to 1200, but we will see what the XDm can handle.

It’s a great time for best mm, even 5 years ago pickings were slim if you wanted factory ammo at all let alone at respectable velocities. Now SD loads from Speer, Federal, and Winchester are in the wild with 10mm specific bullets. Most of the majors have at least an FMJ load. Hornady bumped up their XTP velocities by +100 FPS. A 200 gr Fusion is in the works too. |

Chronod it again and actually wrote down the info.
5 shots avg 1215 FPS high of 1242 low of 1198 I'm beginning to think they changed the load recently. I know the chrono is accurate as I was testing some 300 subs that a couple came close (within 20fps) to super yet didn't crack. but I did chrono some Grizzly brand 200gr from sportsman's that actually felt like real 10mm and it's cheap for what it is <$16 per 20 avg over 5 shots 1263 FPS by felt you know what I mean |
