differences in neck tension question

Well-known member
can anyone answer this. while sizing my 22-250 brass,there are some that when i pull the arm up on my press, i don't feel the familiar bump when the expander ball goes through the neck. and when seating a bullet, there is no resistance at all. i have had the bullet and powder dump out in the chamber a few times latly. i have put in a new shaft and exp.ball but no change. ??

I get that once in awhile as well...I use the One Shot as lube and think it may be due to that...Usually, I will spot check several of my cases with a caliper before charging the cases and then again after seating the bullets, especially the 'easy' ones for consistency in size...

Too my knowledge, I've never had a problem with the bullets slipping in the case in my ARs unless there is another feeding problem associated with it...Once in awhile, I will push down on the bullet nose on the 'easy' ones and they are always tight..
 
Are you using the same cases,or mix,and match? I've noticed that some cases (same brand) have harder necks,than the others.Annealing your case necks can help. I also turn the outside of my case necks,to get a uniform wall thickness. Lastly I use a Lyman neck size die "without the expander ball" in it. This gives each neck a little more tension (seems more uniform,when seating bullets). If any feel too easy,while seating the bullet,I mark the case,and they go into the trash,after the next firing. I use these for foulers,when shooting in a clean bore! Ron
 
Maybe a few cases got a little too hot when annealing and are just too soft. 7-8 reloadings is pretty darn good. I load mine a little on the warm side and only get 5-6 max. I have noticed when using a bench-source annealer than some cases of same mfg. will get overheated. I wear a pair of leather gloves and toss em before they drop in the pan. Do as said above, mark the ones in doubt and use them for foulers. RR

I run my 243 hot! After about 4-5 loadings,either the primer pocket starts to get loose,or the neck tension isn't right any more,so I toss them. Running fast is just like,having the fastest car in town!
