Finally got to shoot my new to me Ruger No1 6.5x55 Swede at the range yesterday. Had some decent results from the 130gr bullets, and 43 grains of H4350. I guarantee you, the floaters were due to my shooting inabilities, than the it was the rifles. It has a 2.5x8x36 VX3, and to be honest, it's not that easy for this old guy to hold the cross hairs moa with an 8x scope....... :-)
I may play a lil more with seating depth, as these were set .150" off the rifling. May try to get em a bit closer. But, even at that, these loads will kill critters all day long.
100yd groups, very light breeze.
