RE: How fast must they go?
Most of the time depending,on the powder,bullets,ect.You come to the attitude of creating to much pressure with a lower powder charge.It can become dangerous. I love to experiment but doing that would become approaching being dangerous with the pressure problems i mentioned.If you like to shoot neat plinking loads in your 06,try using speer 100gr plinkers.They are the half jacketed bullets for the mi carbine and cheap. vangunsmith
