I commend you on an excellent range report there.. Its nice when people take the time to put the details into one. That way, anyone fence sitting about a certain rifle will be more comfortable making their own personal decision.
That rifle is sure a shooter. For the second time out, that is a very impressive group. That group would harvest animals with no problems at all.
Just some thoughts: What is your opinion of the scope? Clarity, focus, dial movements, etc. Also, those shock waves are a strange bullet. When I shoot them in my BDXR I have noticed one will load very hard, and the next will literally side down the bore with little effort.
The ramrod that comes with the rifle does not have a power T handle. But I have found that if you carry a small piece of cloth, like a handkerchief, putting that over the end of the rod, under your hand will take a lot of the bite out of the thing. I actually have a piece of leather that I use. Also when I hunt in the winter, I am wearing gloves (very thick ones I might add) so a tight ramrod is not a problem. Of course we are all aware that technically, we are not supposed to put any part of our body, hand face, etc over the end of the ramrod. Instead we are to grip the ramrod by the shaft and pull down from there. Few do that of course, including myself. Also, why would T/C make a power T handle if they did not want any part of us over the end of the rod..
If the Shockwaves are loading that tight, you might want to try some of the Super Glide model Shockwaves, see if they load better and are still accurate. Also because T/C recommends that bullet, I would never let that stop me for experimenting with other sabot/bullet combinations and seeing how they shoot.
How would you compare recoil with that light rifle? Again, a very interesting report. I will be looking forward to your next range session.
