Is there a dramatic improvement with a 20 Tact/Prac over a .204 Ruger? I was thinking about getting into a "wildcat" cartridge and wondered if there was a big jump in accuracy with the 3 variations listed above. I don't need one ... just looking for something a little different to play with. I am also considering a .223 AI. Any thoughts or suggestions?
A 20 cal rifle with the heavier bullets (40gr V-Max) is a very flat shooting rifle, much like a 22-250, with less cost, recoil, and noise. If you shoot the light weight 20 cal bullets (32grs), then it is not a caliber that has much to recommend it.
I had two .204s and gave up on the cartridge, because of poor brass and the factory 12" twist, and went with a .20 Tactical because of the Lapua brass... I built it with a 10" twist.
At long range, the .223 AI will not shoot as flat as a 20 (Tac or .204) with a 40gr V-Max.
A well built 20, with a 10" twist is really an impressive rifle.
But, if you have need for heavy bullet weight, the .223 (straight or A.I.) will beat the 20 every time.
That is why you need two rifles
