I just got back from Bass Pro where I picked up two boxes of Remington UMC 9mm Luger Mega Pack for the next few times I go to the range. I have read a few bad reviews and seen some youtube videos. The bad reviews said that a few rounds were pushed too far into the casing and others said they had a lot of no fires. Both however gave a decent star rating of 3 of 5. Overall the Ammo has close to a five star rating. Some say the rounds where it is pushed too far into the casing will fire fine, other people say it could make your gun explode. What do you think?

i won't buy UMC anymore. had too many problems with it over the years in the form of uncrimped rounds sunken into their shells, squib loads, duds, not to mention how dirty it is. i've gotten entire boxes where not a single round was crimped and easily sunk into the shells.

it's not going to hurt your 9mm, check it though by leaving the rounds in the tray, and check their heights to make sure they're all uniform.

Cartridge OAL (overall length) is a very critical factor in the pressure of the case. A bullet setback which produces a shorter OAL can easily increase the pressure beyond safe levels. I would not shoot a round that has bullet setback. Even a 0.01"~0.02" difference can cause a pressure spike depending on the powder used and the original OAL.

I shot a decent amount of UMC before I started reloading. I did not have any issues with bullet setback; however, I found the ammo to have inconsistent velocity. It was also fairly dirty. I wouldn't hesitate to shoot it again but I wouldn't pay a premium for this ammo.

I have shot a significant amount of UMC without any problems. Nice to hear that others have had trouble so I can scrutinize but all in all no duds. However some of the federal ammo has been really bad at times

not a major concern with low pressure UMC 9mm. obviously, you still want to toss out the setback ones, but if one slips through it's not going to blow your gun up.

I've shot just one Mega-box of this stuff and lots of the Green & White boxes of 50 rounds in both 9mm and .380 ACP. I've had zero problems with it.

If it is dirty (and I've not noticed it), it doesn't matter much since I almost always clean my guns when I get home.

I've shot a few boxes of it in the past. I don't recall anything particular problematic other than being dirty. I have read of the issues others have had and therefore won't seek it out. If it's all I have then I wouldn't hesitate to shoot it though.

The worst of the commerical ammo!
The Russian ammo works. This stuff has the most failure to fire.

I've used this stuff for years, mainly because it's cheap and available, when Winchester is often not available at any price. The problem I've encountered with this ammunition is that it has a low Power Factor, and can present a variety of feeding malfunctions in pistols (such as early Glock Gen4 9mms) that have heavy recoil springs.

To repeat from other postings, Power Factor (PF) is the number you get when you multiply the bullet weight in grains times the muzzle velocity in feet per second, and then divide the product by 1,000. The PF for their two 9mm 115 grain loads and their 124-grain loads are all below 137, and in another thread we (at least I) came to the conclusion that new 9mm Glocks want a PF of at least 136 to function correctly. That is, before the new Recoil Spring Assembly came out and solved the problem, at least on the G17.

Here's the ballistics data from Remington for this ammunition:

Happily, my 9mm competition pistols are set up with light recoil springs, so I can use this ammunition without problem. It also works fine in the Gen4 G17 with the new "0 2 1" Recoil Spring Assembly.

I don't recall any misfires, duds, or other problems, so the quality has been OK, but I do take the time do dump out all new ammunition on the table and then rebox it, inspecting it as I put it back into the box.

I would use this ammunition for practice only, in a pistol that is set up to use "light" practice ammo. If your purposes are primarily carry or self-defense, I'd look for something with more power.

Shot a hundred rounds of 115gr UMC this weekend with my Gen 4 17. No problems at all. I do have the 0 2 1 spring.

I wouldn't buy UMC if it was ON SALE. Some things aren't a bargain at any price.

I shoot these. Cheap cheap cheap at local Walmart. $52.00 per 250. I can find reloads from Atlanta Arms for about the same price but then have to pay shipping.

I have used this before for my 9mm and have gotten 3 boxes of 40cal for my wife and never had a problem.

picked up 2 boxes of 100 round WW and had 3 bad rounds in one box.

based on all the issues i've i had, i would say this as well, except sometimes UMC is the only 10mm target ammo i can find at the local range. however, i will check it before buying it to make sure there aren't any uncrimped rounds. however, the UMC 10mm is not very accurate, and extremely dirty (and underpowered).

generally though, 10mm blazer aluminum is available. that's great stuff. very accurate in 10mm

i'm rather unimpressed with remington products in general. their R1 1911 is a steamy piece of crap. in fact, they just lowered the price on it by $100 in order to try and sell a few lol

i just snapped a pic of 6 rounds of UMC 40cal 180gr from the 100 rounds megapack. i bought these during the obama buying freanzy when that's all i could find lol. they were all shorter in OAL than then rest of the box. this is how they were out of the box. no setback from repeated chambering:
