Yeah, I must admit that that 40 grain .204 bullet, with it's good BC, holds excellent downrange speed, energy, & wind-bucking ability. The .204 ruger is very close to the .17 rem at short range, and very close to the .22-250 or .220 swift at long range, but it IS superior to them when considering the big picture, that you might be shooting at ALL ranges, albeit by only a little bit. It's interesting for that reason. Plus it's easier to get a cleaning rod through a .20 cal bore than a .17 cal bore. So I foresee .17 rem falling by the wayside even more and more as time goes on. There's a CZ 527 Varmint with HB in .17 rem at a local gun store which has been sitting there at $459.99 for about 5 years - I'd bet I could make them on offer on it - wonder if a .204 ruger reamer would clean up a .17 rem chamber or not? And what would a good smith charge to re-bore & re-rifle a barrel like that to .20 cal?
