It says it is calibrated to 55gr bullets, what differences do you see shooting heavy bullets/ what adjustments do you make
1169605
Correct, this scope is dialed in for .55 gr bullets at 3240 fps. If you want to shoot heavier bullets accurately I would suggest the M-223 with BDC 600 reticle. This will allow you to use Nikon's Spot On Ballistic Program to dial in your rifle, scope and ammo choice.

Yes, you will have to sight in differently for the heavier bullets. If your shooting 77 gr or heavier in the 223 out of a 1 in 8 twist barrel (and you should be if you are wanting to hit anything beyone 300 yards) you will have to sight in and make click adjustments. The 55 gr scale will get you close they make a quick click adjusment from there. It has a scale that you can use just like a normal scope. The optics on the Nikon are excellent and its a very good scope for the money.

I have only shot the PMC fmj bt at 55 grs . My AR has a 1/9 twist . I have the sf model with the turret adj bdc ... not the one with the little circles for Bullet drop . A great scope . But I did put in an AR Gold trigger assy . Same as Jerrry Mickelek uses .

I have only used 55grain fmbt so I can't say what you would do with heavier bullets. I think it's safe to say you would see slower bullet speeds hence more drop at any given yardage.

David, as I recall, if you go Directly to Chrony in Canada ( via the web of course) they have better explanations of the differences between all of their Chronographs . I shot my first BASIC Chrony (after 16 yrs. of use) with a .44 mag. rifle ! Chrony actually gave me a $50 trade-in if I bought up . I bought the Alpha-Red one with the remote display . Cheaper to buy repair pieces, if it is just the box or sky-screens that you hit . Tom D.

What weight arrow and head are you using? also how does it hit at 50 and 75 yds? What scope are you using? Sounds like they are two light.

Lead pellets or ball .177 only , shooting bb's will damage it , it will take a 16.3g pellet but deformed the targets . Regular 5g pellets are fine tho

I have both .177 and 22 cal love them. However depending on how you plan on using your rifle I suggest 1st. get rid of the crappy scope. I installed a UTG 3X9x40 with illuminated GBR mill dot reticle around $70.00 (Optical Planet). Second replace the trigger with a GTX adjustable $30.00 (Air Guns of Arizona) you will be amazed with the difference. If you have to make a choice go with the trigger. I am thinking about adding a sling as these rifles are heavy which is good.Please let me know how things work out.Semper FiMolon Labe CHS USMCL

You can download the nikon "spot on" app and check out how different loads match up using the BDC....its great and printable. I love that scope and utilizing the "spot on" app really helps better dial it in based on ammo using or if you ever decided to put it on a different rifle. But realistically depending on the ammo use its all about the fps as well as bullet weight and coeffocient, but download the app first and you will see what I mean. Enjoy

The title is a little confusing. In short 5.56 is a NATO ammo size and .223 is an American size. The title you have is different from what I have "Trijicon ACOG 4x32 w/Red Chevron BAC Flat Top". The description is about the calibration of the reticle. It is calibrated for 5.56mm (.223 cal) flat-top rifles out to 800 meters.Thanks James Nilandnilandsplace

I have a .223 that shoots 5.56 and I have loaded those, but dont know if the mag is different for a 5.56 but it should be just fine I would not take for mine best investment I have made in a while

Inside 400 yards there is not much difference at all. I have not shot further than that with this scope. I use federal 55 gr as my target ammo and 62 gr steel core for preferred and the zero at 100 and 200 yrds is the same

I've chronographed BB's at 740fps. Haven't measured pellets. If you're using pellets, this will be just as slow to load as your breakneck; loading 1 at a time. BB's are much faster to load but not as accurate.

Think the rim fire is calibrated for rim fire 22 ,such as 22 alar or mag while the other is really for 222 and similar.

I shoot factory a d reloaded 55gr fmj's, haven't done much testing beyond 100yds, but what I have done has been accurate. Scope is clear and focuses well throughout magnification range and has had no issue holding zero.

This hits hard. 50-60 yards consistent. Depending on ammo you can get about 1300 fps with the high velocity pellets. I shoot the heavier lead that runs about 900-950 subsonic but it is way more accurate and packs a punch. Most 22lr rounds are 1250fps but would carry lead further out. It will shoot the 100yds no problem but accuracy just will not be there. I have a ruger .177 that doesn't shoot as fast as this one and they are both way more than the daisy 10 pumps of old

Haven't shot anything heavier that 5.56....YET....however I intend to. I think that as long as you keep the target angled on the chains as recommended and shoot from a reasonable distance....100-150 yards....I'd say it will hold up. I intend to shoot it with 30-06 and 308 soon.

Both of those cartridges are known for having very flat trajectories, but there would be a small difference at shorter ranges that would begin to show up more at over 200 yards or so. It you AR15 is really accurate, I would go for something more appropriate, but if it is not, it would work as a "Do-For". I would check the ballistics on Hornady or any other good site to see what to expect in terms of trajectory difference at various ranges. Good luck, JBPSI was assuming that your AR15 was chambered for the 223, but it may not be, so as Mr. Moen pointed out, there could be quite a bit of difference in trajectory. In that case, buy an appropriate scope.

not bad,on my 22 mk111,I had to reset after about 400 rounds.However,that gun has almost no recoil.

It has load data for the 223, which is the same difference. I use it for my 223/5.56 loads. This is one of the most commonly loaded calibers, so any loading manual will have data on it.
