It's an interesting solution, but... if I get this straight, I can fire a bolt-action rifle on my DEX rank, then fire again at the same target in the same round at the DEX -10 rank (provided I have a DEX of 11 or higher); but, if I fire my rifle at one target, I can't rechamber and fire at a different target until 2 rounds later (because the weapon still has the RoF of 1/2 per round and I have to wait a round to reload). Is that how it's supposed to work?
If that's how it works, it just seems easier to change the RoF of bolt-action weapons to 1 per round.
I did search on "bolt action" and came up with a few threads, but nothing that specifically discussed this issue. The closest was this one, where you posted the above solution. I found Jason Durall's post immediately before that very telling, especially this:
Please understand, I'm not some gunfondler who desires absolute verisimiltude at the cost of playability. I want a system that's fun and coherent much moreso than anything "realistic." That said, I have run a game where this exact issue has come up (someone was working a bolt-action rifle, others were doing other stuff) and it was maddening to try to make sense of within the rules as written.
