6mm dasher freebore

[potatoe]

I am getting dasher built and am questioning the amount of free bore. This is mainly a groundhog rifle looking at Nosler Ballistic tips and V-max's , but would like the option of shooting berger's for the local groundhog competitions. So pretty much my question is which of a longer or shorter freebore would allow me more leeway, would a barrel set up for VLD's allow me to also shoot a tangent ogive or vise versa?

I second DMoran's post 100%. I am having a 6 Dasher built now and after much research and talking to my smith and Kiff, a freebore of .120 to about .125 is optimum for 107 Sierra's which I am going to shoot in my Dasher. And of course an 8 twist barrel.

Dave Kiff swears by the 6 Dasher, call him up and he will set you up with info.

I ordered a .104 freebore to shoot the 105 bergers from Kiff

He gets down right excited talking about a Dasher. I ordered the reamer off his recomendations

Set it up either for light bullets or heavy, not 'one gun does all'.

My dasher is a 10 twist .074 freebore built for pdogging with the 75 vmax bullets and it's a great gun. I kind of wish I had gone 12 twist as it would stabilize these bullets just as well but the 10 works.

If I had to have one gun for targets/varmints I'd set it up for the heavier bullet and use that for everything. Glad that's not the case

If your going to shoot nothing longer then a 95-VLD then I suggest a 0.074" FB
If you want to be able to shoot 105's and light bullets I suggest a 0.104" FB

But I really advise to setup for all out accuracy from 105/107/108 bullets with a +0.120" FB and forget about using light bullets all together.
Seen it so many times where a guy starts out wanting to shoot both light bullets and the heavy match bullets, but soon after find out all they shoot are the heavy match bullets at everything.
Same for twist rate..... go with an 8-twist and don't look back.

Happy Shooting

My "hunting" Dasher is a 22" 8 twist Rock using my reamer with .055" freebore. I wanted a "do both" also, and this works great for 95 VLD's and the 70 grain Ballistic Tips, the only two bullets I wanted to work with. I was not interested in the 105/107's for this gun, so the throating is perfect for this application.

So, with that being said, I'm more than happy with the results of the 95's, so I don't foresee me shooting the lighter slugs, which means I'd build it on an 8 twist, throated for the 105/107's, and take what the lighter ones give you, accuracy wise, when they're seated deeper.
