RE: 3" groups @ 25 yds?
yes.....but remember your first shot each time you practice is the one that counts! It amazes me each fall when all kinds of people show up at the range and have a 14" group....by the end of the session its about 6" and they say there set. Whats really scary is they show up at the range a week or two later AND THEIR FIRST SHOT IS PART OF A 14" GROUP AGAIN!
Its great your practicing!
Good Luck!
