20VT Dimensions

[L Murphy]

What are the dimensions on a 20VT no turn neck? I will be using Lapua brass.

Some may offer something different, but from what I've found, it is .234" for "no-turn" in the 20VT.

I have a 204 Ruger Match Pac-Nor barrel chambered with what TK calls his Match reamer. It utilizes a .230" tight neck, and does indeed require turning of most brass.

Even with Lapua, which usually have large necks, you may still have to trim down to around .012 or .013 in thickness.

I think he’s ordering a reamer and wants to know what the outside measurement is of the neck of a loaded round with Lapua brass and does not want to turn necks.

Yes, that’s exactly what I’m asking. Thanks for helping!

Stuff a bullet in a case. Measure it! Add .002 or .003 to that measurement and you're good to go.
I had issues with Remington .221 Fireball brass converted to 20 VT. New brass was pretty even but fired/converted was all over the place.
Had a reamer built/cut with a .234 neck so I DIDN'T have to turn the necks!. Never looked back.

20VT reamer spec discussion

I ordered a reamer from PTG in April/2015 with a .2335" neck

loaded rds. are around .230" ~ .2305 with Berger 35's

I barely clean up the necks to mic .013"

The loaded Lapua ive been around measured .231-.2315 i would get a
.235 nk. Also add .002 at the .200 line i believe .3765 so you dont get clickers. Call JGS i bet they have a print for a 20VT set up for Lapua brass

I'm a zero freebore fan also except if you wanna shoot the 55's

20 Vartarg Lapua Brass No-Turn
.235-.236 Neck
Zero to .010 freebore

 

[6BRAIman]

I'm a zero freebore fan also expect if you wanna shoot the 55'

What free bore would you recommend with 40gr bullets? 0 .010 .025?

Zero, if your itching for some .010 max thats only if I planned on shooting nothing but 40's
