necessary?? No, but it helps if you crimp. If you can't get a Lee Factory Crimp Die, then more neck tension will be route you want to go

 

[yankee outlaw]

it is a good idea to crimp them

Try without if you don't get desired accuracy then do the BB crimp

Could the built in crimp feature in the seating dye be used? I've never crimped so it's new to me!!

For the dummy in the class, can you start over? Why would you need to crimp it?

If you have enough neck tnesion, you may not need to. I do not on my 308 and RUM and it does well with multiple weights.

I do it with a 7 mag and a creedmoor and not sure I need to, but the small nearing surface to grip under recoil makes me feel better.

So are you doing this so that the bullets in the cartridges in your magazine stay in place?

Hammers are more "slippery" and aren't affected by chasing the lands. For me and many others the crimp refines the groups after the powder charge is decided upon.

Yes. Above.
Crimping almost always improves sd and es. It gives more consistant start to the bullets (both Hunters and Absolutes). Start with a light crimp (1/8 turn). Go up til you find pressure with your powder charge. Back off 1 grain and shoot groups.
Adjust powder and get best load. Do final tuning by adjusting final crimp in 1/8th turns. Your groups will open and close (just like changing powder does). When done, you'll have your best, most accurate load.
Holding bullets snugly in a magazine is an ancillary benefit.
