I'd seat them to the cannelure and crimp, but that's just me. Bullet setback is real in the AR but IMHO, more of a feeding than pressure problem.

I don't crimp my handloads for my AR. I removed the expanding mandrel from my FL sizer and chucked it into a drill. Ground about .001 off the expander ball. This will give you plenty of neck tension and this method is described in the Sierra guide.
If the powder is at the case mouth you're going to have compressed loads which will cause a lot of variations in COAL.

Few things if you want to use cannelure start at minimum charge and work your way up as you normally would for any new cartridge or bullet powder combo no big deal don't make it hard.sooo if you want to seat further out closer to rifling lands or mag length then do the same thing start at minimum and work your way up.no reason to over think it.
Start low and work your way up if ever concerned on a load, but if you have data for that bullet weight and powder start halfway if velocity is your goal .main thing start low and work your way up no sense in damaged or prematurely wearing gun parts for 100fps.if you want to crimp go ahead it's easy precaution in a semi auto just work your load up.i factory crimp all my semiauto rifle rounds with lee factory crimp die one of the good things lee makes.but you can always make dummy rounds and charge them into gun then measure to see if feed ramp is jamming bullets further into casing. easy
