Here we are, two months after the CHALLENGE'S first post and not many pics, so I tried the same rifle combination with which I met the 300M challenge--and stepped down to 100M-- I had to chase a couple of groups because the initial shot went a bit low-- and I'm still not getting "warm weather groups...but here's what happened.
Rifle is 30BR in Barnard S action / Krieger Short BR -- Smith work by Karl Schmidt
barrel / CG Trigger / Reiben Stock
