  1. Perhaps old news, but I missed it if so. Processing some range brass 10mm, I discovered a percentage with small primer pockets. The cases were CCI-Speer-Federal. Most were Blazer headstamp, but Federal as well. Stopping to think about it, it shouldn't be a surprise, but I don't load a lot of 10mm, so it was the first I knew about it. This was the first brass I've gotten in 10mm in quite a while. More sorting required.
  2. Many years ago, the Air Force designed a more accurate 20mm projectile. Later, when they first started testing 9mm pistols, they concluded the bullets then available were not accurate enough for their tests. They got with Hornady and used the 20mm design process to design a new, supposedly, more accurate 9mm bullet. That was the 124gr Hornady truncated cone bullet. Hornady later used the design process for a new 45 bullet, resulting in the 45 truncated cone bullet - tha6t should actually should have been 235gr, but they kept it at 230gr. I've not been able to find the original Air Force research - assuming it was published in some paper or standard, but the concept was that the center of pressure needed to be in front of the center of gravity. Hollow points do that naturally, along with the truncated cones. All that said, I feel it still comes down to individual guns as well as the bullet. Some guns have distinct preferences for what they will shoot well. Generally, however, hollow points and truncated cones should be accurate. I have not seen anything about semi-wadcutters, but expect they are a modified truncated cone.
  3. Develop a load first that is reliable and accurate in the gun. Then, if you want, modify the gun to better "fit" you.
  4. It looks like the point the resizing die stopped sizing on a fairly large case. Or a slip up when the extractor groove was cut.
  5. I have not used any Shellshock cases, but I have seen sparks with brass cases from time to time.
  6. Did you enjoy the shooting?
  7. As I understand the chambers, the 223 (SAAMI) chamber has a short leade. The 5.56mm chamber has a fairly long leade that has not hhad the greatest reputation for accuracy. The Wylde chamber somewhat splits the difference, giving a longer leade than the SAAMI chamber, but shorter than the5.56mm. With respect to chambering a cartridge, since the two gauges are accepting the cartridge, but the chamber is not, the chamber has some difference than the gauges, obviously. Could this be dirt or debris in the chamber interfering? Have you tried chambering the round again? Areas of concern include the bullet contacting the rifling, the neck diameter, the position of the case shoulder and the degree of sizing on the case body.. 'I do not know where the Dillon sizing dies falls with respect to sizing the case body. Standard RCBS and other dies do not size all the way down the body of the case. A small base sizing fie sizes further down compared to the standard sizing die. The case neck diameter may be affected by a case having a thicker than normal case wall, or, perhaps, a random oversize bullet giving a larger OD. If the sizing action did not bump the case shoulder back sufficiently, that would interfere with chambering. You might blacken the cartridge and try it in the gauges and the chamber, looking for the contact points. That may enable you to determine the source of the problem.
  8. Kuhnhausen has a book, and there are the Collector Grade books - War Baby and War Baby Come Home that may provide some background.
  9. The value may be important to your heirs. It may or may not stay in the family years from now.
  10. I'm the first to admit I don't understand big business, but it seems it would have been better to copy the car companies and have different "badges" to cater to different markets. Leave the STI line to competition (it got them where they are), and establish a new brand (Stacatto) to cater to a different market. Think Ford - Mercury, Chevrolet, Buick, Toyota - Lexus. That way you would be following Marketing theory and growing, but no abandoning your base. In my opinion.
  11. Taran Tactical Innovations comes to mind. About an hour from Hollywood.
  12. If you are not chamfering inside and out before using the new brass, try that to see if it eliminates the shavings.
  13. Sorry, I'm not following that answer. Specifically, were the cases that experienced bullet seated too deep all the same head stamp, or different? The other questions stand, as well.
  14. Were the cases all of the same make (headstamp), or mixed? Did you look at case wall thickness? Have you measured a sampling of the bullets to look for variations in diameter?
  15. You can load and shoot the smaller diameter bullets, but it may not be worth the effort. The smaller bullet will not obturate the bore well, giving lower velocities that may result in the bullet tumbling. Even if it does not tumble, accuracy is not likely to be good. You will also need an expander ball suitable for the 0.308 bullets. Otherwise the case may not hold the bullet. This assumes you have a standard barrel intended for the 0.311 bullets. I have one gun that was built for what we'll call the 30 x 39. It uses 7.62x39 cases and 0.308 bullets. IN all,. I think you would be happier using the bullets correct for your barrel - 0.311 diameter unless you know the barrel is made for the smaller bullets. .
