I would have to say YES INDEED. OK, I know one test does not support this statistically. But with results this dramatic I am convinced. Both 5 shot groups below were shot at 50 yards with my cap lock 50 cal Hawken GM LRH barrel and using 300 gr Shock Wave bullets and 100 gr of FFg. The only difference was the group on the left was with the sabots that came with the shock waves. The group on the right was using Harvester black CR sabots.
During the course of the shooting I did notice that the T/C sabots varied in the amount of pressure required to seat the bullet. Some were tight, others only moderately tight. The CRs were consistant with each loading.
On a side note - to ease Cayugad and Semisane's mind, the fouling with this rifle was about what you would expect with BP. (barrel was treated with MX BC). The only difference between today and yesterday was I swabbed the bore with 2 alcohol patches and dried prior to shooting. After each shot, the barrel was swabbed with a T/C #13 patch and 2 dry patches.
