[@j.till_z]

He has done a video on a 25/300, 50/200 and 100 yd zero. From zero to 200 a 50 yard zero is pretty consistent, but once you reach out past 200 the bullet drop is significant.

[@davidmilisock5200]

The M193 does even better with the 20" barrel on the A2. My A2 in 5.56 in a Delta configuration is almost as good as my Aero Precision M4E1 in 6MM ARC with a 16" barrel and 105 grain Hornady match.

[@Driver-ur9mf]

​@@davidmilisock5200Makes sense. Cartridge was made for that length. Had only been shooting green tips from the carbine, but is way to cold for outdoor range and they say no no to those indoors. So a vid about non green tips and perhaps insight into 11.5 and 20 inches would be good.

So now I'm GLAD (again) that I have mostly M193 55 grain. I was starting to think about switching to something heavier since some say heavy equals accurate, but your practical test kind of says otherwise. Thanks!

[@ryanfirst9761]

These videos always interest me because I use to zero mine at 100 which is difficult with my old eyes. I use mine for hunting so I use to zero at 100 yds, but switched to the 36 a while back. Now I’m switching bullets to a 70 grain and know about what I can expect.

[@johnbowman1052]

Great Job on these videos. I love how you tell us about the Gun and setup, what ammunition, explain trajectory theory, and then announce each group of shots before they occur. Without this we are just looking at another video of bullet strikes in a go pro. We know it is 50 yd zero, 100 yard shot etc... I and people that I shoot with refer back to your wrap-ups over and over so we can get it right the first time and not waste expensive ammunition verifying our equipment. I have never been able to get people to understand on the first try and you do it every time. God Bless you. I notice you often refer to what your ballistic calculator says and you are verifying it with your equipment. I am a re-loader and like many have nearly no way to verify a 200 yard shot. Perhaps you could show us how to run the numbers on a ballistic calculator and then verify on a 100 or less range the information from our gun with inches high at 100 and so on. I think this would be very practical for nearly everyone that lives in more urban areas that can never get long shots. Just a suggestion Keep up the good work. I bet you are making a greater contribution to the shooting community than even YOU know. Having spent much time on the range I realize this type education takes much effort to produce. keep up the good work, we'll be watching.

[@johnmarken3945]

Nice to see the 1:7 twist was not a detriment to the 55gr at all. Great to see that physics haven't changed and that a 14" barrel doesn't give the heavier bullets enough velocity to be as good at 300 yards bullet drop wise. Seeing the limits of that system, no magic bullet for shorter barrels in 5.56. Is what it is. Also confirmed that the m855 sucks accuracy wise, I'm not alone. You do seem to take our comments and use them so now I'd like to request and see this run with a proper 5.56 barrel length of 16" or even the original stoner length of 20" that the system was originally designed with for the 55gr vs heavier. I'd also love to see similar work done with the 6mm arc which I am coming to believe is a superior battle caliber for the AR15 over 5.56. Thanks so much!!

[@seanoneil277]

M855 seems best suited to learning recoil etc. management in fundamentals, more than anything else.

[@davidmilisock5200]

@@seanoneil277 The M855 was designed for better penetration from the shorter barreled M4. It runs at higher pressure than the M193, therefore produces higher velocity in the shorte barrels and has a steel wire core.

[@Driver-ur9mf]

​@@davidmilisock5200I had questions about that. FFL always seemed to have a can of Winchester M855. I read of an EPR or M855A1 for the Carbines, which seemed to imply 855 is for the 20". Well this EPR allegedly has faster burning powder for the shorter barrel. Faster burn equals more pressure, but complete burn in 14 inches. I told him, I'll have that. He says nope, civilians may not have that. Bolt breakage, or something. I don't know.

[@davidmilisock5200]

@@Driver-ur9mf The M855 (green tip) came to be when the M4 was in general use for a while. The M855A1 (from what I could find) does have a higher pressure, however the one issue that seems to reappear itself is feed ramp wear since the M855A1 has the steel tip on the outside. If my memory is working, they created a different magazine for that cartridge.

[@LarsBars17]

Bro you spoiled the ending for me

[@GetMeThere1]

Most of us use M193 for practice, and most late-manufactured barrels have a 1:7 twist -- which is FAR faster than M193 requires (original M16 had a 1:12 twist). I'm interested in the effect of 1:7 twist on M193 bullet travel -- especially as it gets out to longer ranges.

[@davidmilisock5200]

My only experience with the 1 in 7 twist is with the the 20" barrel on an A2. The answer to you question is from my experiance is that the M193 is very stable in the 1 in 7 and if the wind cooperates my A2 can make repeatable 600 yard hits.

Great series idea, this is good stuff! I was very surprised by the 62gr performance at 300y (wide disbursement)., as well as the amount of drop (13 inches) of the 77gr from 200-300yds. I wasn’t expecting the 77gr to be higher at 200y than the lighter bullets but that amount of drop was crazy! Makes me wonder if the shorter barrel length contributed to that drop. In addition to optic height, muzzle devices, and barrel lengths, I’d love to see barrel twist rates with different bullet weights added to the list because I’ve read how a 1:9 won’t stabilize a 77gr down range and how 1:8 is the perfect all around compromise, etc.

@@IkfNorCalChamp yes they seem to have been not very accurate at the distance he shot but next time you go out & shoot them say at 700 yds you will see that they will shoot better than the 55g fmj’s or 62g , at least that’s what I see in my rigs because of the higher bc of the 77g . Your rifle will ultimately tell you if it likes them or not .

[@blahblahblah7554]

More videos need to be like, RL testing. Very practical. Have you ever tested another type of 0ing other than what is commonly used to see if there is a better grouping at the 25, 50, 100, 200, and 300 yards

[@MrFred4513]

Another great video. You have no idea how these videos help people who dont have availability and or access to longer shooting ranges. I like seeing the heavier 5.56/223 bullet info they are becoming more popular and available. Perhaps a video showing a 77 grain bullet zeroed at 25 yards , 50 yards and 100 yards and the results of those zeros at 300 yards.

[@1GruntZPOV]

I think another cool idea would be to zero with a certain bullet and than shoot out to 300 with 55, 62, and 77gr to show the margin of error. From personal experience I competed in a competition while in the Marine Corps and we zeroed with 62 gr m855, but during the steel shooting segment of the competition we were given 77gr mk262 so that we didn’t damage the steel targets. We had to shoot out to 500 and the zero change was surprisingly not very much. This was with a 100yd zero though. With a 36 you would probably see a drastic change

[@Driver-ur9mf]

Have seen gunsandgear doing reviews where he runs from 45 to 77 grains. They print all over the place. Sometimes the very same projectile from various suppliers. Sub moa to 4 moa in same rifle. But I think this guy is talking zero, or center of group impacts for various zero. That said, the other channel's center grouping was not similar from same rifle, same zero, same distance.

Awesome video bro. I personally don’t like using 55 grain ammo. I could never get a good group. I have a 16” 1/7 twist barrel on my range rifle. And it seems to favor 62 grain more than anything. I’ve shot heavier loads & I wish I could shoot more of it to work the barrel in more but man that stuff is kinda expensive. So if I buy anything over 62 grains it usually goes to storage.

none of these groups are on the orange target dot at any of the 3 ranges, which is why I prefer the 50/200 yard zero, you'll be slightly high at 100 yd on target @ 200 yd and about 8-10 inches low @ 300yd with the 50/200yd zero.

From a military aspect, you really can't beat a 200y zero for engagements in a predominantly urban enviroment (or for civilian use as home protection either).

If he used green tip LAP rounds for his 62 grain ammo then his group is poor because of that more than anything, especially at 200 and 300. Those steel cones inside the 855 ammo aren't as concentric as lead is. So the slight variation in where the weight actually is in the projectile is what throws those groups further than what you'd think.
