I have chambered four of these new rimx actions, they are very nice. these new action have a few features that the vudoo does not. Removable bolt head. you can buy bolt heads for 22LR 22mag, 17HMR and one other I think? This action also has a bayonet style takedown of the bolt, similar to a Bat. The magazines are very well made and quite a bit heavier than the vudoo magazine. This doesn't necessarily make it a better magazine but certainly a dam fine magazine .
The Long range 22 or NRL style of shooting has really become popular. I must admit I enjoy it myself.
My person Rimx action shoots every bit as good as my benchrest rifle. truly amazingly accurate. Great product and very simple to chamber for. No extractor cuts either, that's another great feature Lee
