I have have several 6-284's and the case is just too large PLUS it isn't based on the 243.
I like the Ackley if you want to shoot factory, when necessary. The 6-47 L isn't based on the 243 but is easy to get to shoot really well provided the rifle is good.
The 6 SLR can have shoulder issues with Lapua cases.
The 6 Creedmoor is great but not strictly on the 243.
I would go Ackley or get a 6 on the Lapua or Creedmoor case.
