STOP it then; as there in lies the biggest part of your problem. Also, you gain no more accuracy by neck sizing. Even some of the TOP bench rest shooters full length size. AND make sure your cases are not too long.8208 can be an excellent powder in some 223's. Try somewhere between 27-28grs with a 40 gr Nosler (of course) bullet. Start lower, as that is a full house (SCREAMING) load. Flatter trajectory in other words, along with less muzzle jump and recoil. A win, win, win situation all the way around. If that load won't work, then 28.5 grs of Benchmark with same 40gr bullet should and at nearly 3800 fps. COOL... I get high on SPEEEEED! OH... And Welcome to the Forum Frank
I neck sized the cases only.

Mike, it has been many years since I loaded brass more than 5 or 6 times. Of course I did have case splitting problems back then but just don't remember the details. I no longer keep brass after 4 times of loading & thus (almost) never have splitting problems. And all my loads are max as we both know. lolAnyway, a couple of the biggest reasons for case splitting IMO is due to poor lots from the factory &/or old, brittle (fired) cases. Letting the cases getting too long & over max length can be another. Dies, or not setting them right could be another, but probably not as likely. Probably? Can be a number of possibilities! Also, ALL manufacturers of brass can & do produce bad lots of brass including the TOO expensive Lapua, Nosler etc. Buying the more expensive stuff will not eliminate this problem in other words as some mistakenly believe. Oh, and yes, reduced loads would increase brass life, but I see no point in that, in a "hunting" round. While each barrel & chamber is different & can certainly have different ceiling levels of pressure, on "avg" your max 223 load, exlusively, does not sound like the problem to me. Possible of course, however? It does sound like the load may (or may not) be a tad (1/2 gr or ?) higher than should be, especially if the (consistent) accuracy is still there at the slightly less powder charge. But again?Clear as mud, eh? lol But hope this helps... a littleFrank
Frank, do your case mouths crack sooner with those speeds? The hot loads I slowly worked up to for my .223 Rem with H335 would split the case mouths after about 5 or 6 firings.

Frank, it takes me about an hour to get to my range as well, but being a private club, I usually have the range to myself during the week! We have a 250 yard rifle range and a 50 yard pistol range as well as trap and skeet. The Riverside County Swat team uses our club, but members take president. They are usually there on Wednesdays.

Paul, I go to the Angeles Range close to where the 210 & 5 fwys meet. Exactly 2 miles north of foothill blvd on Osborne st.It takes me almost an hour to drive there, which really sucks. Plus I almost always go on either Monday, Tuesday or Wed's only. Thursdays the police are allowed to have the entire range whenever they choose and Fridays are almost as busy as the weekends, with all the gang bangers out there. Too bad we couldn't use them(gangters) as targets. Now that would be TRUE justice!Good Luck on your reloadingFrank

As stated, neck sized rounds will sometimes start fitting pretty snug. I'd opt for a properly setup F/L die that is set to bump back the shoulder .002"But for the .005 expanded section just below the shoulder? You might be running your case into the seating crimp (if it has one) and are slightly collapsing your case. If your cases are varying in length, the longer ones may be running into the crimper. Maybe try running your seater up one turn or trim all your brass to one length.
Federal once fired brass (in this gun) with a Nosler 55gr ballistic tip on it. Went to the range and several rounds will not chamber in the rifle, seems that below the shoulder the cases had expanded by .005" causing the cases not to chamber. I neck sized the cases only.Has anyone ever had this happen? What could cause this to happen?Thanks in advance!Paul

I hate spellchecker!! :)No seating crimp, running these in a bolt action so no crimp needed.Thanks,Paul

Most seating dies for bottleneck cartridges have a crimp machined in them. Shooting these from a bolt action is irrelevant....you could shoot cannelured bullets or crimped rounds from your bolt action if you wanted. I'd back off the seater die a 1/2 turn.
