Finally got my SPR build up and running. this is at 4 shot group cause I didn't have a fifth. 40gr V Max in front of benchmark powder. Can remember the charge. This is only at 50 yards things look promising for the 100 yard line. I didn't think the 40s would do very good in a 1/7 twist they shot the best between some 64gr Winchester Ranger and some other 55gr hand loads I had got some 77gr Bergers going to try next. Barrel is made by McGowen Precision Barrels in kalsispell MT.
