I was in my local gun shop stocking up for muzzleloader season when I came upon 170 gr sabots from DRT. Dynamic research technologies. What drew me to it is the light weight of the bullets which I am hoping helps my son. I am hoping that the light bullet reduces recoil and increases speed so the bullet expands correctly. At light loads we have had poor bullet performance.....thank goodness he can shoot well. I was wondering if anyone had any experience with this company or its bullets. I am leary of things that seem too good to be true. Thanks for any thoughts.
