I have a .22 RW HP and a .25 DW (with a .22 slow twist barrel kit). I've had the RW for about two years, and the DW for about a year. The groups above, although excellent by any definition, are not unusual for either rifle. Both of my guns shoot like this under good conditions. I haven't done much slug shooting with either since I have a couple of guns specifically for shooting slugs, and all the major 100Y, EFT, and Speed competitions are pellet only, so these two are my top pellet guns.Â
For me, the RW is easier to shoot accurately off a bench, both are fairly easy to shoot off bucket and sticks or prone. The issue with the .22 is the quality of the .22 RD Monsters. Some batches were very good, but MOST required an inordinate amount of time sorting to minimize the probability of flyers. This is an issue that I don't see with the .25 Heavy pellets in the DW. My .25 DW likes the King Heavy best, but I've heard from others whose DW's like the Mk2 best. So you need to try both if you have a .25 DW. I have not tried slugs in my DW, but in my RW HP the .217 JSB KOs shot exceptionally well at 990 FPS...
