20Dasher, 20x47 Lapua or other for long range varmint

Depends on the chambering if your just necking down not to much to worry about as long as your not trying to shoot max. loads right off the bat. If your trying to AI a shoulder then mild loads.

my bad. not a very clear post. I'm having a 20 dasher built and have never fireformed br brass to dasher before

The 20 br improved will run 3900 but it wont shoot there other than hunting accuracy

George,
Why do you say the 55 gn Berger won't shoot at 3900?

Well as far as hunting accuracy it probably will work it will but brass will not live very long there I used it for target the magic number was 3750 fps an the brass stays longer.

George,

My previous post refering to 3900fps with the 55 Berger was out a Dasher case. I think the BR case would be closer to 3650fps.

Do you think the 6BR AI would do 3750?
