I'm new to ML-ing this year, and I purchased the T/C Black Diamond XR special from BassPro earlier this summer. For a sight, I mounted a Bushnell Dusk & Dawn. (BP just moved to town this year, so now I have a place to keep all my extra money.)

I've made two trips to the range so far, and had mixed results. In both cases, I shot 295gr Powerbelts (hollow-point) with 100gr of Pyrodex (pellets).

On the first trip, being new, anxious to get some shots off, and such, I was getting ok results. That is, tight groups at 50 yards with open sights. I had the scoped shots within a couple of inches of where I wanted them, again at 50 yds. That's all the time I had that day.

On the next trip, I started off at 50 yds, and wasn't seeing the consistency like before. I was all over the paper. So, I have yet to move on to greater distances until I figure out what's going on.

Reading up, I'm seeing that there may be an accuracy issue with using Powerbelts at or above 100gr of powder, especially with the hollow-points. At this point, I'm ready to move to a different projectile, and I purchased a box of 777 pellets, of which I intend to stick with the 100gr equivalent.

I'm asking for advice on the projectile. I've heard good things about the T/C Mag Express (some came with the gun, but I haven't used them) and T/C Shockwave Sabots as well as Powerbelt aerotips.

I like the way the Powerbelts load, and the general concept of the full-sized bullet versus the sabot. I also like the feel of the shots with 100gr of powder. I'm not convinced that there is a huge benefit to the 'mag' loads. My friend, who has the same rifle (albeit 2 years older), has had good luck with the Mag Express sabots using 150gr of Pyrodex.

I failed to mention that this is a hunting application, so I am mainly concerned with stopping power and accuracy up to about 100 yds (150 max).

Which, in your opinion, seems like the more appropriate path?
Thank you
