Tough call on the sbr.....I think i saw a ballistics chart for various barrel lengths for m193 and m855 somewhere.....50/200 on 1 of them, 100 yrd zero on my scoped AR, 50 yrds on the SBR but I have no idea how much drop it will have at 100 yards since it is such a short barrel I need to do a Chronograph check on it and see where its at . and a 200 zero .223 on my bolt gun
dont want to hijack your thread but i figured why make another one on this topic.At what range do you zero your AR and why?
Kinda odd that if fell off at a 12" barrel lengthfound a chart from sadefencejournal.com for m855....
I haven't gotten that far yet!Q and Jon what did you think about the 36/300 that was discussed on that DVD?
jjfuller1, I would zero hers at whatever requires the least need for holdover. I'd think it would be easier for her.
I like this image. Would you happen to have 1 for a 50 yard zero?Fixer said:My C-more is set at a 25 yard zero. I know my trajectory will equal my POI/POA error out to 375 yards.
here's a diagram of my reasoning. I teach both the 50 and 25 yard zeros. I choose the 25, but let the student choose his/her zero.
I guess it's a Marine thing. It's supposed to zero your AR so that there is no holdover out to 300-400 yards. That section is very interesting.I haven't gotten that far yet!Off the top of my head it doesn't add up.
well, sort of. you are correct that we used 36/300 zeros..we sighted in at 36 yards. but for shooting, the closest qualification target is 200 yards. goes 200, 300, 500. we did other training with shorter distances, however we always used the same zero... incorrect on holdover. we learn to make sight adjustmentsI guess it's a Marine thing.
