        What type of objects can you reasonably expect green tip ammo to penetrate? I saw in another thread that using green tip exclusively (outside of training) is a good way to go, but I just want to understand what green tip can do for me since the Internet seems to be full of conflicting answers. I know that level 3 armor can stop it, but I’m also curious about other objects…say, not-too-small-to-hide-behind trees, cinder blocks, etc…things someone might try to shield themselves with. In short, what are scenarios where having green tip might tip the scale?

          I would say that the majority of rifle plates out there in civ and LEO world are only level III which green tips will defeat. From that stand point, having green tips is a good idea in SHTF since these plates will be most likely used. Green tips go through stuff better than 55 GR FMJ. Remember all the internet blah blah blah about terminal effects of 55gr FMJ, well those effects are great when you shoot someone without armor in your home, but those effects are not so good when you shoot stuff like structures, vehicles, etc. Green tips are better at penetration for just about all current building materials for housing in America.

              I think M855 green tip is an excellent choice of combat ammo. I think a lot of all that static on line about it being ineffective was more due to shot placement versus it’s lack of effectiveness.

              As to body armor. Well, I think it has a very good chance of penetrating it. According to some combat vets that I trust, practically any armor can be penetrated by repeated hammering in the same spot. Even level IV armor is tested with multiple hits at least 2″ apart. If you shoot someone into the ground, keeping all your rounds in the upper thoracic region, you stand a very good chance of blowing right through his armor. That’s if you have the time and skill to do so.

              If you hit even level IV stuff with 5, 10, 15 rounds of green tip, hammering in the same spot (not a failure drill), you will stand a very good chance of breaking through. I know that sounds pretty unbelievable to many, because you were always taught to do failure drills. But I have talked to guys that have done just that, and wanted to pass that on, for your consideration. Note #1: If you are ever in NC, stop by and I will try to arrange for your to talk to one of them in person. Other than that, I cannot “prove” it to you. Note#2: This is also why you see top instructors insisting on accuracy and tight groups in training.

              But back to green tip, and other objects. Again, I would say “cover” would depend on who is shooting at you: as in how accurate they are, and how many rounds they send your way. If most any object is no better than body armor, and by that I mean repeated, accurate fire will eventually defeat it, then it would behoove you shoot and move! So most trees, cinder blocks, autos, etc. are probably temporary cover at best. Probably hold up to a few scattered rounds thrown at them, but if someone really knows what they’re doing, they will try and blow through it. If they have the time and skill.

              Inside structures, like typical houses, it’s a crap shoot. It can penetrate but then again it can hit plumbing n shit and deflect. I have read that 5.56 does not “over-penetrate” any more than 9mm in house firefights. Green tip would probably a bit more effective than typical FMJ, but then “over-penetration” might be an issue, depending.

              So yeah didn’t mean to go off into the weeds, but I think most folks assumption of effective protection from small arms fire is probably off a bit.

              Bottom line, yeah I think green tip is a good idea. I’m stocking up on it myself.

                That’s quite helpful. Thanks, guys. Guess I’ll also have to test it out myself on trees and things around.

                  This goes to your estimate of the situation. If you are expecting inner-city gang-bangers, I wouldn’t expect their marksmanship to be up at these standards (worst-case scenario), but, as the man said, I train to beat my evil twin, who is (almost) just as good as me.

                  Same with an active shooter incident. What would his marksmanship look like? Possibly somewhat better than your average gang-banger. Possibly even a lot better.

                  There are evil dudes out there practicing as much as righteous ones. Count on it.

                  In training we typically put IPSC targets on stout trees, around 20″ in diameter. They will typically contain single rounds.

                  Dirt berms are very effective cover. I would want around 2′ thick, for overhead cover on a position.

                  Sandbags usually work, with densely packed sand or earth. But they will start to tear up after repeated hits. I would stack 3-4 deep.

                  Steel plate is iffy. Good AR 500 (level 3 ) and such will take repeated hits. A good plate will take over 100 hits. But much steel is unknown and green tip will punch right through it.

                  Ceramic (level IV) will take initial hits; as long as they are at least 2″ apart, it will take repeated hits. But you can hammer through it with repeated hits in the same spot.

                  But at the end of the day, I think your best “cover” is to put effective fire on the enemy. And then maneuver on him. Cover may not just be available in any given situation. You may be maneuvering with a team and be forced to take up a position to stay in alignment with them, rather than the perfect spot of cover. You may be assaulting (or breaking contact) where there is no cover at all. You may have to drop to kneeling (or even prone) positions to lower your profile because that’s all you got.

                    DiznNC, not to get to into the weeds technically, but how do you account for the drop between your “practice” 55 gr ammo and the 62r stuff?

                    When I start thinking about different loads, things like BUIS, DBALs and Scopes that need to be adjusted for each rifle come to mind. I am sure I am overthinking it (at least a bit), but I am an engineer and have a little LR shooting background that I have to overcome to be practical sometimes.

                      The velocity and ballistic coefficient differences, and thus the trajectories, are not that great between 62 grain M855 green tip (3000 fps, .304 BC) and 55 grain M193 (3165 fps, .251 BC) to affect point of impact that much at typical combat distances. At least not for “battle rifle” accuracy.

                      With a 100 yard zero and a 300 yard target, M193 will drop about 2.5 MOA. M855 will drop about 2.1 MOA. That’s less than an inch difference. Even considering the 100 yard zero offset between the two rounds, you’re still well within a couple MOA. That’s plenty effective for the typical rifleman (but maybe not for the DM or and certainly not for the sniper).

                      I’ve found this to be practically true. My scope is calibrated for M855. I can zero at 100 yards with M193, switch to M855 and hit near the center of a head and shoulders D target at 300 yards using the reticle holdovers. Good enough!

                        I chose M193 back in the day and stuck with it. Most people in my AO use m193 and so its an option and I stuck with it due to ranges banning m855 in the area. Do I feel underarmed, not really. I could be the one out of many with m855 but, I do have 2 cases in the basement from when it was the same price as m193 for a few months, of it but when I could buy 1500 rounds of m193 for 1000 rounds of m855 it was an easy choice. We all have reasons why we pick certain rounds.

                        I have a stash of M855 at my family ranch that is just that…a stash. It is getting harder and harder to find anywhere to shoot it except the local outdoor ranges and then only into the dirt. I have not bought any in a few years and I think my supply is ample. I have been buying M193 variants and Wolf Gold almost exclusively for shooting and hoarding over the last couple of years. My rifles like the Fed Fusion MSR so I am building up a stash of this also. Food is at 3 months not counting the ready stuff. I always have and always will do something every payday to prepare for emergencies.

                          Also to add to BrianGA, most of the 55gr FMJ ou there being used is not M193. M193 is Lake City Federal. So most of the training 55gr is PMC and such. It’s velocities are less than the M193. However, as BrianGA says, it is not significant enough to worry about. At 300 with a 100 zero, it drops 2-3 more inches than M193. Doesn’t matter, you still hit your man. Minute of Man (MoM)

                            As others have said, the difference is not enough to worry about.

                            I do the same as others, my BUIS, ACOG and DBAL are all zero’d using Federal LC or Winchester M855. I use M193 for all my training. I will periodically shoot drills with M855 to keep myself familiar with my hold overs.

                            As hellokitty said, there is a difference in real M193 and what some company calls M193. The same goes for M855.

                              Hey Texas:
                              Yeah it’s like they said, for me and what I’m doing, it’s still minute of man. I don’t think you’re over-thinking it as much as you just have to switch gears depending on your role. If I was a designated marksman, doing more precision/long range shooting, yeah I’d be more concerned with it. But for GP work, where I’m shooting at generally 100m or less, the differences are pretty much are negligible.

                              I will zero, and validate zero with 62 gr green tip, most every trip to the range at 100m. But when I move in closer CQB distances for training, I will switch out to 55gr. Or when I do a class and shoot 1,000K rds.

                              Technically you are right, in that it does affect my accuracy, but again at the distances I’m shooting it’s not enough for a miss. Now that being said, when I move out to farther distances, do things change? You bet. There is a noticeable difference at 300m. If I aim at the top of the head, the green tip flies “flatter” and will hit high thoracic area. With 55 gr I am aiming over the dude’s head to get a hit. So yeah, it’s a little anemic once you start getting out there.

                              I have recently converted one of my rifles to a “designated rifleman” type of config, with a free float bbl and a 1 x 4 power Loopy scope. I shoot 77 gr though it because it has even better performance at longer ranges.

                              So yeah I hear ya, it really depends on what I’m up to. If I’m doing strictly marksmanship training, then it’s green tip. If I’m doing tactical work then it’s 55 gr.
