I have been tryng to narrow down the distance where my .22 will still group.I already think 400yds is too far for mine. Yesterday I shot a 10 shot group at 300 yards. 3inches wide,7.5 inches tall. I believe I can get rid of the vertical stringing with a front stock modification.My stock is sticking in the bag. I also think once I have sorted bullets the group will improve more.And my bench technique could be better. Keep me posted on your rabbit hunting.
