Accuracy wise? The RimX is more accurate but not demonstrably so. My RimX is more geared towards a competition setup as I like to try and practice positional stuff and shoot long range. Functionally they aren’t that different The RimX mags are just outstanding and just work perfectly every time. They are great to load and are so well constructed. They are literally just on another level from other 22lr mags. The bolt on my Bergara has a hard close and lift even with the factory trigger and hasn’t smoothed out even after thousands of rounds. I just think it has to be a function of its design. The bolt throw also isn’t as smooth. The RimX bolt throw is fast and smooth. Also, the bolt throw and lift is much smoother and easier than the Bergara. I like the Bergara and for the money it’s a great rifle but it’s not a Vudoo or RimX. I also love how easy it is to take apart the bolt to clean on the RimX. The RimX setting up in the MPA chassis was literally plug and play. No adjustment necessary transitioning from the Bergara but that may be because I already had the mag catxh adjusted to the correct height. It did take some fiddling to find that sweet spot for the Bergara but once found. It fed reliably. The Bergara now sits in an Element 4.0 chassis that is both light and comfortable. I take it with me in the woods and just like to shoot with it. I can hit acorns with it. Nice setup but I did have to put tape on the back of the magazine to prevent the front of the magazine from dipping. Mag height wasn’t a problem with the Element 4.0.
