I think you can do better also, I dont know what your load is or your bullet/sabot combo but with My V1 at 150yds I can put them all inside that 4" square with no problem, most times I get a 1 1/2" group, and that's a bad day.
I use a 110grs of pyro rs and a 240gr xtp mag with a mmp hph-24 sabot, all my CVA's shoot this load extremely well.
