Mine has never been an issue of kick, but rather accuracy. I always seem to get better accuracy with two pellets rather then three. Congratulations on the rifle. You have just started an impossible addiction, but it sure is fun. Report back to us on the gun, load, etc... and let us know how everything is going.
Only advice: Keep your routine (cleaning, loading, powder amounts, seating pressure, etc...) from shot to shot as consistent as possible. Then you can change one thing (i.e. up the powder charge) and know the exact result.
