In my eyes, the only valid reasons for not using "heavy" for the FT would be that their manufacturing quality is worse or that their balistic coefficient would be less than 0.0235.

This is only a theoretical opinion of course.

Last 4 years as a good little well-disciplined student, I used AA Diabolo Field 4,52mm, but I'll do some tests , just to see if the theory is consistent with the theory.
Not sure about heavies but I tested 7.9 and 8.4 in our windy field before switching to the 7.9's and there was hardly anything in them I'm talking a pellet or twos width at most. I found that the 7.9 was more consistent than the 8.4s though so switched over.

Tested side by side alternating in the same conditions
