I have shot the TMK in my 6XC.

Accuracywise they stand right there with 105gr VLDs and A-Maxes, producing 1.0" - 10 shot groups at 100 meters.

Performancewise they expand more violently than the A-Maxes, and less violently than the 87gr V-Maxes.

With the A-Maxes I always got pass throughs on broadside shots on roe bucks, and about 70 percent of the time on big Kalahari sprinbucks.

With the TMK I only had one pass through out of four roe bucks, all of which were shot broadside,

Just my two cents.
