The 200 grain Thompson Center Shockwave with the blue sabot is an impressive projectile. I went to the 100 yard station with them and the Black Diamond XR and took the heavy bench rest. I also took some Rusty Duck pre lubed swabbing patches for swabbing between shots.
Roseaukaine.. as you mentioned, when you put the projectile into the sabot it does flower the sabot and looks like it is not seated all the way to the base of the sabot. I was not sure the reason for this, but in my rifle they loaded into the muzzle very easy. On a clean barrel they slide down with moderate force on the ramrod. I could feel the sabot trying to grab or stop against the side of the barrel but they did load fine. I checked my witness mark between loadings and it always came back to the same place. I even loaded them with the ramrod that comes with the rifle to duplicate field loading conditions. After shooting the above groups, I then loaded two more of them on a fowled barrel. Although it was harder to do, they still loaded fine.
Since they are such a light projectile I figured they would want a stronger powder charge, so I decided to kick them up to 110 grains of Pyrodex first. I was more then pleased with the group. Their location in relation to the target left something to be desired. These things hit much higher then the 375 grains Buffalo Bullets I normally hunt with using 100 grains of Goex 2f. The slight amount they hit to the left will have to be checked further. Perhaps the scope need some adjustment. But since I was only looking at how they loaded and behaved on the range I was more then pleased with a little over a 1" group out of the Pyrodex. Then I turned the box over and got ready for the next set.
Before I loaded the Triple Se7en FFg in110 grains, I ran three Rusty Duck cleaning patches through the rifle and several dry ones to make sure the rifle was as clean as possible. I was amazed at the little amount of actual fowling left behind by the Pyrodex. And there was no sign of a crud ring at all.
The three shot group of the 200 grain Shockwaves with the Triple Se7en measured right at 3/4 of an inch so I was more then pleased with that. I then shot two more of them without swabbing the barrel clean to see if I could load them. This opened the group up to 1.5 inches. I had a flyer. At least it went into the bulls eye.
Overall I am real impressed with the 200 grain shockwaves and the way they load and shoot out of the Black Diamond XR. I saved some because friends are talking about doing some long distance shooting this weekend. I figure where they are hitting right now, a slight adjustment left to right would be in order but the elevation might be very close to where I want to be... time will tell.
