Prior to last year I was using the 250 gr TC shockwaves with the easy glide (yellow) sabots over 85 gr of loose 777 in my NEF Sidekick. I consider my ML to have a "tight bore" and this combo proved to be a very accurate load. I harvested a couple deer with the shockwaves but wasn't satisfied with their "on game" performance and went in search of another option.
I've always been impressed with the Barnes bullets out of my slug gun and figured I'd give their muzzleloader bullets a try. Started with the Spitfire MZ and TMZ's but both were next to impossible to load. The 250 gr. TEZ on the other hand loaded just right, very comparable to the shockwave easy glides.
After experimenting with varying amounts of powder, I found its sweet spot shooting a 3-shot group at 75 yards measuring 1/2" center-to-center. More importantly, I harvested a deer during ML season that left behind the blood trail that seemed to be lacking in my prior experiences with the shockwaves.
If your ML has a tight bore the TEZ's should load smoothly, yet firmly. Being the TEZ's are a flat-based bullet vs. the boat-tail design of the Spitfire MZ and TMZ, you can buy aftermarket sabots (Crush Rib or MMP) if the TEZ's load too easily where accuracy suffers.
Time and $$ permitting, I plan on trying the 290 gr. TEZ's next year to see if they shoot as accurately as the 250 grainers. IMO... it's hard to beat the terminal performance of a Barnes bullet.
