love 20 practical. I use a .223 bushing die to do the necks. 1" drop or less at 200 yards depending on load/bullet combo.I have been shooting Prairie Dogs out to 450-500 yards with .223 55 grain for 14 years. Nothing cheaper will do that AFFORDABLY. 17 HMR is great but costs .35 cents a round if you can find any and that isn't easy. I love a .204 Ruger but if you find any, it is $2.00 a round and brass is super hard to find. Similarly with .22 hornet, .22-250 (maybe the king of long range accuracy since the .222 Rem Magnum is about history). BUT.........
IF YOU RELOAD, take a serious look at the .20 Practical. Uses .223 Brass, easily necked down to .20, uses less powder than .204 only about 100 FPS slower and shoots like a laser. Low recoil, lower noise than .223 and a real joy in bolt actions. Sold my .204 cz, wish I hadn't. Rebarreling another bolt action in .20 Practical now.
