    68-69 grain .223

    I'm looking for a coyote zapping load for > 200 yd ranges in .223/5.56 for a 1x9 barrel. I see that 77 grain is too long/heavy for a 1x9 but I'm currently stuck with that b/c of budget issues. It looks like the 68 or 69 is the heaviest I can do. Does anyone here run that kind of bullet and like it?

    Don't rule out going light either (52's). Get the Sierra Manual and look at their "Most Accurate Load" (or something like that) and you're probably done. After a lot of load testing, this worked out to be the best in my 18" AR.

      Competition

      I use to use the 69gr Sierra before they got to expensive. I used 24.5gr of WCC 844 or H335 With OAL of 2.255. Have a nice day

        See my signature. A lot of people will tell you 75 and 77 won't shoot in a 9" twist. These people have likely read it on the internet and not tried it. They may also tell you that a 7" twist will cause 55gr bullets to explode.

        Anyways, I have not found a 9" twist that would not shoot the short 75 and 77 bullets. By that I mean the Hornady 75gr HPBT, and the Sierra 77 Match King. I've shot both, and like both. Hornadys are much more cost effective, and have a better ballistic coefficient, so they will drop less, and be blown around by the wind less than the Sierras.

        Now that I said that, the 68's, 69's, 75's, and 77's should all shoot in your barrel and ANY of them will be fine for 'yotes. The 75's and 77's will carry more energy though, if that's a factor to you.

          so which ones perform better at 600 yards?

            Not sure if your making some green kool-aide comment or what, but I know plenty of people who's rifles like the red box far better than the green box. The sierra's are easy to get to shoot well because their ogive shape tends to jump into the lands better than the secant ogive of the Hornadys. This is also what makes them have a lower BC. In other words, Hornadys are a little more sensitive, and therefor harder to get to shoot well. The Sierras are awesome because they require much less load development to see results.

            As for me, my rifle shot the 75HPBT better at min charge weights, but I haven't been able to do any serious load development yet. But maybe my rifle just likes Hornady's better because it's a savage and it's not as good as a Remington, so it likes sh**ty bullets?

                Yes. Hornady 75hpbt have secant ogives, 77smk have tangent ogives. There isn't an answer to your question because different rifles like different bullets. If only sierra or only hornady worked at 600 yards, thats the only bullet they'd make.

                Keep your name calling comments to yourself. If you've got a point to make try to access the part of your brain that processes facts and examples.

                  52 or 69 grain nosler custom competition. I've been using their 52 grain bullets for awhile now and they shoot just as well as the 52 grain sierras I was using for varmints.

                    Does anyone here run that kind of bullet and like it?
                    Yes, I think the 69 grain Sierra are great bullets. I weighed a number of them and they were same weight or very, very nearly so. I also measured some and they were the same length or within .001".

                    Since I got a new rifle I've been experimenting a little. Rifle has 16" barrel with 1:8 twist, polygonal rifling and a wydle chamber.

                    I loaded 20 rounds usig new IMI brass, 24.3 grains of 748 with OAL of 2.250.
                    I shot four groups of 5 shots using 4 power Accupoint with the green triangle reticle.

                    I also shot my usually 55 grain FMJBT with cannalure.

                    Result were that the Sierra rounds had group size that was consistanly at least 1" tighter than the Remington 55 grain bullets. All at range of 100 yards. I little wind that day but not much.

                    I got a box of 77 grain Sierras that I want to try but I think I'll shot them to 200 yards and compare them to 55s and 69s.

                      Bullets with good specs doesn't always mean better accuracy. My tactical 3-gun rifle has a 1:8 barrel and shoots 68 better than 55's but my Limited rifle has a 1:9 barrel and shoots the 55's better.

                      Its a bit of a crap shoot if you're using someone elses load data if you don't have the exact same barrel and even then its not a guarentee.

                      The only way to be sure is to load up a few different combo and go out and shoot them.
                      where are my pistol mags?

                        I really like the Nosler 69 grain custom competitions. Never tried the SMKs yet because the Noslers are cheaper and I get everything I want from them -- sub-moa accuracy at 100 yards (as long as I didn't drink too many beers the night before), and I can pop the 12" x 18" plate at 300 yards all day long, with irons.

                        69 grains should be perfect from that 1:9 barrel of yours.

                            The two on the right. If I'm not mistaken its a 77smk, a 75hpbt, and a 75amax. The two hornady offerings have secant ogives.

                            With that said, what does it matter if one can look and see the type of ogive being used? BC cares way more about ogive that my eye does.

                            And either way we're way off topic. OP: TRY 75 and 77gr bullets before you just dismiss them. Like I said, I've never met a barrel marked 1:9" that didn't shoot those bullets well. It's when you start looking at the 75AMAX and 75VLD length bullets that the 9" twists usually start to under stabilize the bullets.

                              look kid, I been at this a lot longer than you have, so don't try to school me on what bullet works in what or what constitutes a secant/tangent ogive...
