As if you need another opinion....

Since it seems like a 50/50 split as to whether or not guys think it may help I'd look at trying other things first. In the end, it is one more variable to keep in-check and consistent...and being able to do THAT when you're reloading WILL better your accuracy.

I only load for my 22-250 right now (as far as rifles go) and don't use a crimp
But I put a borderline over-healthy crimp on my revolver loads. I did find the harsher the crimp the better consistency...but straight-walled revolvers and shouldered bolt actions are two different games!
