90gr of FFG and a 300gr SST for me. And its accurate further than my eyes allow me to shoot. In a pinch, I'll go two pellets and the SST and there is no noticeable difference.
No noticeable difference.......... that's because you never looked on the ground and saw all that black stuff on-top of the snow after shooting that 3rd pellet load. Sometimes even a fireball occurs and one clump of black may be seen yards away in the snow.
The Black Diamond XR and the Omega are two of the best, most accurate MLs old T/C ever produced. Had T/C began the Encore ML-making process with an oversized hinge pin, that one would have been also included on the Top-10 Greatest Inline MLs ever. White Rifles and Knight Rifles have multiple models planted on that list too.
