Suggest you buy Todd Ks 20 book. Decent amount of info.Any experience or thoughts, thanks
For some reason Todd shortened the 222 parent case by approximately 0.1 inches when designing the 20VTT. 20-222 is better choice in my opinion. If one wants a little more velocity consider the 20 Practical(20-223). The 20 Practical has approx 10% more case capacity than the 20-222.Any experience or thoughts, thanks
That’s pretty much what my coyote rifle is and I’m here to tell you a 40 Berger at 4000fps is quite the stuff for killing coyotes DRTFor a larger 20 cal some of us really like our 20-223AI's. Easy to form, no brass growth and easy 4000 fps with 40 gr bullets + great accuracy & lots of brass possibilities.
LA50SHOOTER, just curious here, but why would you go through the extra work to improve the 222 case when all it really does is match a 223 case? You could have saved yourself a little time and money by building a 20 Practical.
Better brass, including Lapua and Norma, for the 20 VTT. Less powder and heat means you shoot longer without stopping. 204 Ruger has maybe 200fps on it. Honestly, the only reason to go 204 ruger is to have cheap factory dies and off the shelf ammo. Everything else is better with a 20 tac, 20 practical, 20 VTT, or my personal favorite, the 20VT.Anything one can do w/ 20 VTT,you can do faster and a lot less trouble with a 204 ruger,especially with 40 grain bullets.Unless you are shooting at High Elevation like 4-5000 ft or more
There is Zero Data listed to load 40 grain bullets in 204 ruger at 4000 fps,I believe Accurate 2520, X-terminator one can reach about 3900 fps out of the right rifle.The fastest loads w/40 grain bullets are listed at 3850 fpsAnyone care to venture the pressures involved when achieving 4000 FPS with a 40 grain bullet in a .204 Ruger or smaller case?
Thank you. My point exactly. 4,000 FPS is in the high pressure zone in a .20 BR let alone anything with less powder capacity and there simply isn't any easy (or safe) 40 grain 4K FPS happening in a .204 or smaller case. Can 4,000 be achieved? Yeah, probably. You'll never catch me attempting such a stunt though. Seems like "measured" rifle velocity numbers tend to get rounded up just like the weight of that trophy bass...or the quarter mile time of a hot rod...or the length of a golf drive on the 12th hole.There is Zero Data listed to load 40 grain bullets in 204 ruger at 4000 fps,I believe Accurate 2520, X-terminator one can reach about 3900 fps out of the right rifle.The fastest loads w/40 grain bullets are listed at 3850 fps
