I used 2225 for the heavier projectiles( above 150) bedding would be my next place to look. If it does shoot good groups then its a small vairable because if it was a serious problem or fault it would never shoot good groups. Sime tikkas weren't quite free floating as they should be especially at the fore end tip. Worth looking at
