103 vapor trail

[ebert]

what should the free bore be for 103 vapor trail in dasher with lapua brass

 

[Jet]

Should be? I don't know but I use them with my .135" FB and they work fine

 

[Dusty Stevens]

Theyll work from .120-.155 perfect.

 

[bblackwell]

.155 works very well in the Dasher.

 

[Thumper]

.104 works fine

Ok i can see the numbers here.
.104 .120 .155
These numbers are around 1/8 of an inch more and less.
Lots of free bore numbers kicked around these threads from jam up or touching 3 or 5 or 20, 30, 50 thousandths.
Is this really supposed to be .0104, 012, 015?
Honest question.

No .104-.155 is correct. There are a wide range of freebores that work in a dasher. I have them from .099 to .155fb. Its a personal choice but as short as the neck is on a dasher it should not be longer and to keep the base in the neck it shouldnt be shorter

If you take the difference between .104 and .155, you have .051. If .104 just has the pressure ring right at neck shoulder junction, the .155 just moves it .051 ahead of it. You don't want the pressure ring even or below that junction. I like my pressure ring to be in the sized portion of the neck. If using bushing dies, they don't size all the way to the shoulder. I bet .135 is probably the most common used. Matt
