Do you crimp for your semi .223?

look buddy I have been reloading for over 30 years . I've reloaded for semi's , pumps, levers and bolts so I think I might know a little bit of what I am talking about. I don't proclaim to know it all but I do know enough to tell when someone else really doesn't have a clue of what they are doing. I have gave you some good advice in some of my post but you choose to egnore it and rather just try to insult me.
I am new at this and all aspects of firearms, your right I don't have a clue, that's why I'm asking. I've read a manual, researched the internet whatever, but not all the answers are there. Ok so I made a mistake setting the die, I remied that on my own. Lots of people gave me good advice , which may be different than yours, so who do I listen to? I had a problem with some of the PROJECTILES 
not being crimped tight enough. I can now tell which ones, because of lack of pressure when seating the projectiles(5 out of 30). No disrespect to anyone, but this is not rocket science. I'm sure 30 yrs ago when you started it was a bit different than now. So , you see where in coming from, no matter what advice is given, I still have to figure, which to take. And I felt you insulted me, and I just lowered myself and responded in kind. So please accept my apology , and let's move on. We're arguing over the internet about reloading.

We're arguing over the internet about reloading.ok apology accepted and if I came off as insulting in any of my post trying to give you advice well then I also apoligize. Reloading 30 years ago was pretty much the same as it is now granted we have some better tools and reloading supplies to work with these days. But one thing that hasn't changed in 30 years is the fact that if carefull attention isn't paid while reloading terrible things can happen. Just in the last few months there has been a few posts on here about rifles blowing up and seriously injuring people. One I remember was a guy used a cleaning rod to remove a bullet stuck in his rifling from a round that didn't have a powder charge in it or something. Well the guy somehow forgot to remove the cleaning rod from his barrel before firing another round, guess what happend. Another one was a guy reloaded some round with the wrong powder and blew is rifle to peices and his hand I might add. So Accidents can happen , but they also can be avoided by paying close attention to what you are doing to ensure that what you are doing is correct.
I'm trying to be careful, there's just so much info, and it all varies. Some of the problems I've encountered , I can't find the answers anywhere. Example.. I loaded 30 rnds , 5 of them were not seated tight enough( I could push them back into the case). So after thinking about it , I concluded, it couldn't be either of the dies,as they would all have the same issue. So I remeasured all the cases , and the 5 problem cases were all 176 in leanght( the max requirement )? So maybe this is the problem. Again I don't know and can't find this info anywhere. Anyway , thanks for the input, I do need all I can get, that's why all the threads.
Are all of the cases you are using the same brand? Are they all from the same batch of brass? Brass dimensions vary with brand and even batch, and those variations in dimensions can cause the issues that you are describing.
I said I was done , but I'd like to add one other thing, I'm new, and I wanted t I see if crimping is nesasary . So after research and opinions on here, I've decided that crimping is more of a personal choice than a safety issue, I don't see a problem with it if that's what you want. I think my issue maybe from case lenght. I've had 5 out of 30 , that I could push the projectile back in the case. I could also notice no pressure while seating these 5 bullits. Upon checking the lenght of these 5 cases , I found them to be exactly at the 176 lenght. If it were the dies at fault, they should all be a problem
Are you sure you already used the sizing die? Sounds like you are loading new brass that hasn't had the neck sized. My seating always has pretty high resistance. You cannot get the bullet to move without a tool.
like one of the previous poster asked , are all of your brass of the same head stamp? Your brass should all be trimmed to the proper legth. Different brands of brass have different thickness . If you have brass that after resizing with not hold a projectile tightly then disguard that brass. Not sure what kind of brass you are using if it is stuff you picked up at the range or stuff that you have saved from factory ammo or what. Its hard to give answers if we don't know all the details
Yes I'm sure , I resized all 100 case a second time , after I set the sizing die correctly, most of my cases were under 175,a few were over 176 , which I trimmed, a few were right in the 176 which I left as is. Is it possible these are the problem?
Also like to add that the projectile could be easily pushed into an unsized case. With the five loose cases , all projectiles couldn't be pushed in, prior to seating. The projectiles all sat on top of the case , with me having to guide them into the die. The only difference was, I could feel no pressure on the press handle , at the end of the stroke, for the 5 bad rnds. Also , they were snug, I couldn't pull them out by hand but could easily push them back into the case. I'm gonna retrim those 5 cases , to see if that changes anything.

If the Rem brass has been fired a few times it might have become work hardend. Which means it springs back to more its original size after you resize it. If it is work hardend then the only cure is to anneal it or to disguard it.
Trimming
yes max case length is 1.76" so when you trim you should trim to 1.75" . So if some of the cases are over you are best off to trim them all to the same length of 1.75" . After you trim them champher inside and out side of the neck

being a little under is no big deal , being over could lead to problems because when you chamber the round and the case neck is to long it may hit the front of the chamber and accually start to crimp the bullet. one thing I would like to add is you always meaure and trim ( if required ) after resizing. It is the resizing that makes the brass grow in lenth
