Hi Pete. On my H bar, I come up around 7 clicks from the bottom setting, and shoot off the top of the post like an apple on a fence post for a bullet strike in the 10 ring. Works perfectly for iron sights. The rifle likes lighter bullet weights and slower burning propellant, IMR 3031 etc. For best results, less is more. That is a great shooting rifle. a joy to shoot. thanks for the vid and the sea story. USAF 73-77

Thank you for your service Pete. Enjoyed the video, my buddy had two Colts one with a 1:12 and a 1:7 twist. He was so unhappy with that 1:12 even in a vice it was so sporadic, I bought a S&W M&P15 s2 with a 1:9 government barrel ( at his recommendation) he changed that 1:12 to a 1:9 and bought 2 more AR15's the same as mine. He liked the 1:9 the most after experimenting with different weights. The only difference is our 1:9 are 16" rather than his 1:7 , that was a 20" barrel. I've had a lot of"experts" tell me the 1:9 is garbage, but,I've had really good results with that twist. I try to stay with 55gr. Or 62gr. These videos are really helpful, thanks! , Lön

I have quite a few 1:9 twist AR's and haven't noticed any difference even up to 68 grains but I just about never shoot past about 200 yards these days so maybe that's where something happens? No experience at all with 1:12. I have been running quite a few 1:8 twist Wylde chambering's lately and have noticed a slight accuracy improvement difference with some .223 vs a 5.56mm chamber but nothing I could detect as related to stability?

Thanks Chris! I'm definitely going to take the Sporter back out and get the zero straightened out with 55 grain. It was shooting decent groups when I was doing my job so I just need to get it dialed in better! When there's more ammo availability I will be trying even more bullet styles and weights. Can't remember watching any vids where anyone was complaining about Black Hills anything. Thanks again for watching!

let me get this straight...! You want to have your BUIS zeroed at 25 yds.? Your irons are about 2 inches above your bore when the gun fires...that zero at 25 would put you fairly high at 50 yds. and perhaps off the paper at 100yds. I would opt to be zeroed at 50, with a little rise in impact at 100. I'm thinking that your 25yd. zero mey be why your front sight is screwed in so deeply. So tell me...am I just FOS?!

Both the A2 and A4 sights were designed and calibrated for the Army using the 25 meter distance for zeroing on the 20" rifles. For zeroing using the Army method the rear elevation drum is clocked up one click for the A2 and 2 clicks up for the A4 detachable handle from mechanical bottom and which places the A4 drum at the "Z" mark. Not all A4's have the "Z" mark. Small aperture is used on both styles for zeroing. The front sight post is then adjusted for POA/POI. Once you have your rifle sighted you return the rear elevation drums to the 300/800m bottom position for the A2 or the 300/600m bottom position for the A4. You are now zeroed using the small aperture for 300 meters for the 20" rifles. You can then flip to the large aperture for 0-200 meters. If you are using an aftermarket BUIS on a flat top then you can make your zero for what ever you want it to be even if you're still using an A2 front sight base whether it's "F" marked or not as the rear adjustment calibrations if your's has them are usually more recommendations and guesstimates. For that application I will go with a 50/200 yard zero. For Milspec irons I will use the Army 0-300 meter because that is what the rear elevation drum was designed for. I believe the Marines started using a 36 yard zero on their M16's but they eat crayons! Lol! Thanks for watching Alanna!

Hi Pete, Remember, at 25 meters flat trajectory, just raise your gun up and put the front sight post at the top of 10 ring. You should get the bulls. That's with the 55 gn. Still, your weapon is tight. I was hitting targets out to 600 yards. With 62gn. Even at 600, you have to elevate. Always allow for bullet drop. Great video.

Thanks! I definitely need more practice! Most of my range days usually involve function testing on new stuff. My goal is to get accurate with little support or aids. I see a lot videos with sub-MOA results but most of the shooters are using enough support equipment to where they have mostly removed themselves from the equation. Don't know if I'll ever get there but it sure is fun trying! Thanks for watching and commenting!

@Peter Egger Pete, I don't use support equipment. The one thing I don't do is take myself out of the equation. Our ancestors did not have support aid. It is pure ability. I generally sight my weapons at 100 yards or 200. Once I have the bulls, I leave it there. If you have a good scope with graduating cross hair's, just elevate the weapon like an artillery piece. Only for distances beyond you zero. Does that make sense.

@@crashoverride4881 Yes, it makes perfect sense! I never touch the dials once I'm zeroed for the type of shooting that I do. Just make the corrections with the reticle. I'm almost always within 300 yards these days though. I've often wondered why anyone buys a scope without a ranging or BDC reticle. You can still hunt with one of those but it is much more difficult to shoot precise long range, competitive or tactical with like say a standard duplex when not at your zero. A standard duplex still has its uses and a lot shooters are very good with them but the reticle itself is still very limited in what it can do.

I think my 1:9 HBAR Colt does a little better with the lighter stuff I shoot. Thanks for watching!

From rear sight settings as you set them, the 25 meter zero is set turning front sight post and rear sight windage drum. An exacting zero can be made using a target that is big enough to distinguish a consistent center mass sight picture. At any rate, it appears that your extreme elevation need is possibly from having poor but consistent sight alignment, and/or a low sight picture. Also, when an A4 is fitted with a commercial rather than mil spec detachable carry handle the rifle will shoot too low to be properly zeroed. Of course, your low grouping was from the A2 so the proper carry handle sight is not applicable. Hope you figured it out. BTW, these days, Mk262LR ammunition from a 1/7 twist makes M193, and M855 moot, as well as the 1/9 twist rate. The 77 grain Mk262 round is .64 MOA accurate at 300 meters and good to mid range, having an MOA wind constant of 8.5 at 600 meters. M855 only has an MOA wind constant of 7 at 300 meters, meaning it will not get desired results at mid range. The Mk262 round also syncs well with the bullet drop compensation and 300 meter zero functions of A2 and A4 rear sight. One more thing, the National Match Bushmaster made some years ago had a 1/9 twist barrel. A friend of mine shot 75 grain AMAX from it in 1000 yard NRA Long Range Competition and never any keyholing. In fact he once won the Kentucky State Long Range Championship with that rifle and loading from iron sights.

After I retired from working I decided to get back into it mostly being AR's and realized I wasn't seeing as well when using irons. Had my right eye lens replaced about a year and a half ago which helped a lot! To accurately get past 100 yards these days I need magnification. I still enjoy trying with iron sights though! Now my left is now starting go. I'm right handed but left eye dominate so my left eye is only a problem when pistol shooting with both eyes open. A lot of good info in your reply so thanks again!

@peteregger7928

Жыл бұрын

I think most of it was driven by military testing in very cold weather as far as the twist rate goes and certain types of military ammunition. The heavier stuff is claimed to be more accurate as ballistic coefficients are often better with a more varied selection of bullet types available. The heavier stuff at long distance will be less effected by wind. For the ranges I shoot at 55 and 62 grain non-steel core name brand stuff has been more accurate than I can usually shoot. Some rifles will shoot heavier stuff better and some the lighter stuff regardless of twist rate until you get below 55 grain. I personally haven't seen much of any difference using 77 down to 55 grain with 1:7 or 1:9 at the distances that I usually shoot. I think there's credence that below 55 grain a 1:7 twist might be too much and the preferred twist will be 1:9. I do believe my 1:8 Wylde chambered rifles have been slightly more accurate when using .223 or NATO at 55 grain or above. Not sure how things would go at 1:8 with very light bullets as no personal experience? There's so many variables it's hard to give a solid answer? Thanks again for watching and commenting!

My groups were not as good as I thought they should be, compared them to my 1:8 (not Wylde). That's when I discovered the twist rate/ammo thing. I did pick up some 69, 75, and 77gr. to test that 1:7, yep much tighter groups. Since I was already stacked in 55 & 62, I just couldn't justify the increased price for the heavy stuff, 1:8 and 1:9 works great. Just wondered your opinion why so many manufacturers are pushing 1:7. Since I don't see myself going out beyond 300-400 max, I'm really liking my 1:9's for all varmits 2 and 4 legged. Thanks again.
