I don't crimp either for my Ar unless I use cannelure bullets, then i crimp a little.

TanDa, where are you located ? Maybe I'll come by sometime and give you a hand. I have been reloading for about 15 years now

Since it hasn't been mention
The diffrence between semi reload and bolt is:

Full length sizing, this is very important because it will almost gurantee a jam if you don't full size a semi-auto brass.

That's the most important part of semi vs bolt reloading. Other then that the painful and annoying steps of prepping the brass such as:
Punching primers out, cleaning primer pocket, swag/crimp remove primer pocket crimp if you ever get military brass, trimming case, chamfer/deburr neck....yeah... Those are what bugs me more then charging and seating bullets.

+1 on full length sizing. You can't get away with just neck sizing for auto-loaders.

If you are trying planning on reloading mil-surplus brass (i.e. Lake City), make sure you swage the primer pockets to remove the crimp otherwise you probably won't be able to seat primers.

Good intro read:

I crimp all my reloads.

Probably not necessary and I may try my next batch with out a crimp to see how my AR likes it.

Ah, yeah, you need to read a reloading book.

This was absolutely the best advice whether it stings or not. Nothing can match the time spent reading a good handloading manual.

Even Raymond's video's (No offense Raymond) can't replace actually reading a good manual over and over. This will give you a better comprehension and understanding of the process.

Then Ray-Ray's video's will make sense ahellovalot more and you'll benefit alot more from them. Otherwise, you may find yourself scratching your head and saying "What does Ray-Ray mean by that?" You learn the lingo so that you can understand what a handloader is talking about when he is speaking to you.

My $0.07 worth.
