Just got my 2nd 6 Dasher back from the smith. Sako Varmint laminate stainless that was a 22 250 and got it re barreled to 6 Dasher. Krieger 8 twist barrel 104 free bore. Shoots excellent with 105 berger hunting vlds but im planning on using this rifle on crows magpies and yotes and want a bullet with better expansion. I have a pile of 75 v max to use and need a starting load and help with choice of powder. I have H4895,Varget, N135 and 8208xbr. Any help would be appreciated, thanks.
