When I used to take my 6.5x55 to the range, noone knew what it was. They just saw some plastic synthetic stock thing. But Everytime, after I shot a couple of rounds, the guys next to me would Always come and ask what it was. I thought this was strange until one day I let a mate fire off a few rounds while I sat at the next bench over. As soon as he fired I felt a shockwave wash over me. Fark. No wonder they asked me what it was.
I only used to put 20 rounds at a time through that beast. And when you hit live targets... begeezus... they stayed hit. Once shot a roo in the head and when we got to it the entire top half of the head was gone!
204 Ruger. Yeah Janx, when it came out a few years back (2004) there were articles written about it in all the related magazines down here. Gun shops had signs up. Salesmen would mention it as an alternative to people asking about 223s etc. But I like to think the proof is in the pudding. If it was as a good a caliber as made out, word of mouth would have kept that sucker in good sales like the old stayers. But still, it's in the top 10 of reloaded calibers so there must still be a good number of them out there.
I have a sneaky feeling Ruger brought it out in the hopes it would take over the popularity of the 223 as a varminter. Least, that's my theory.
