Chains?My vote is for larger.
My rationale is we could use multiple smaller chains to rig it versus two larger chains that would increase the chances of someone shooting the links and decoupling the target from the stand.
If we used a smaller target it would be less durable and would get plinked into oblivion a little faster than a larger and girthier target.
I believe we are talking about the public range target at the 100...which has no chains.
I did notice that someone hung another steel target using rubber at the 100, which was there as of Sunday night.
