What advantages does a 20 practical have over the 204 ruger?

What advantages does a 20 practical have over the 204 ruger?

Brass cost and availability.

What advantages does a 20 practical have over the 204 ruger?

Advantages: Barrel life, brass cost, no caliber specific dies needed, you can use .223s,
Disadvantages: Factory built guns and ammo widely available, if reloading, no neck down process, small gain in velocity.

Will a Redding .223 FL S die with the proper bushing work?

Will a Redding .223 FL S die with the proper bushing work?

Yes, with some modification. remove the .223 button and replace it with a .20 caliber one. I use two bushings and two steps to neck down. Final bushing size is dependent on loaded round diameter and desired neck tension. After the first firing, I dont use the button. One caveat with this round, unless one wants to work with different size bushings, stay with one brand of brass as .223 neck thickness varies quite a bit across manufacturers.

There's more info on the process here: http://www.accurateshooter.com/guns-of-week/gunweek061/

Good read. I also wonder if you could use the .223 S die to neck size .20 TAC once formed?

 

[GrocMax]

20 tac and prac you can use a cut down Lee 204 collet die as well.

They had a $30 off sale in Feb. I put a 11tw on order for not much more than a stainless 12tw green mountain. Looking forward to getting this 20 Practical together.

Received the barrel in less than 2 weeks.

It looks like you got an 11 twist. Even better!

Yeah, thats what made me go with the X-Caliber over the Green Mountain.

X caliber three groove 20's are fantastic in accuracy and a lack of copper fouling....you will not be disappointed!!!

Matt, I am also looking at a 20P as is a buddy. Keep in touch on reamer and barrels. He wants a rifle and I want to see what it will do in an XP with a 13-16" barrel.
I had tossed around doing a rifle build, still not ruled out.
I am on the fence bouncing back and forth and narrowed to 223AI or the 20P.

Does anyone sell ready to go AR-15 barrels in 20 practical?

 

[Jdne5b]

Black hole, X-caliber, white oak. Shilen might, but they only list a .204 Ruger caliber.

Recommendations?

Recommendations?

I'm still in building mode of my first one. Just ordered the reamer. I'm using an 11tw X-caliber blank, and my gunsmith @300rum will turn and chamber it.

From what I researched, any of those barrels would probably be fantastic. I would have went with cost and lead time if I was picking from those.

20 practical. Love my AR Rich Johnson. Building a 2nd in bolt platform.

I'm going to start gathering up parts for a 20 practical build. If i find a 204 cheap in the mean time I'll grab that.
