I've been a long time 22 accuracy nut and have tried a lot of 22 sporter weight rifles (my own self imposed limitation) to find a couple that are very accurate, repeatably and measurably so.
If I'd seen this series of videos before I on sold several rifles that didn't quite make the grade I'd have saved a lot of time (but probably not money haha) - its simply the best explanation of the mechanics of the 22 RF ignition/chamber set-up I've ever seen.
Here's the link to the most important vid in the series but the whole lot are worth watching - he works on high end rifle in the vids but the principles apply to any 22 after the basics such as bedding etc are taken care of.
