A couple three days ago, i realized i haven't been shooting bullet from the stash of 270g Deep Curl. So, i figured i ought. Then i realized i had no CDS dial made for the 270g Deep Curl, and sat down to order one from Leupold Custom Shop. Before i made the order, i examined the ballistic of the 270g Deep Curl, and the ballistic of the 300g Deep Curl.
That is when i realized the cds dial for the 300g Deep Curl would work just fine with the 270g Deep Curl. It seems this same cds dial may work for other bullet too, but i haven't looked any further. This 'generic' cds dial did save me $90.
