I'd like to hear from long range 22lr shooters on groups they have shot at this distance. I use a Anshutz 54.18 silhouette rifle with a 10-40x Osprey scope mounted on it for ground squirrel hunting. My best results were a average of 2.74 inch groups for 5 shot groups with 50 rounds using 4 wind flags, with a best group of 1.05 inch. That's shooting Eley black with eps bullet.
My hunting round is Remington 38gr. hollow point. With this round I averaged 4.25 inch
with the same 5 shot groups for 50 rounds. I use rubber o-rings on the barrel to help tune the barrel resonance.
I know in 22lr silhouette shooting the ram at 100 yards is supposed to be comparable to a 500 yard shot on a full size ram with a .308 Winchester. Does that make a 200 yard shot with a 22lr on a small bore ram, which is about the size of a ground squirrel, comparable to a 1000 yard shot with a .308 on a big bore ram?. ifldned
