STR with Explosion HKA

[torgo]

If I have a 3d6 HKA with explosion and 45 STR, do I get to do a 6d6 explosion? Or do you figure the active points of the str with explosion for the purposes of determining the added STR damage? in this example:

45 STR = 45 active points.

30 * 1.5 (Explosion +1/2) = 45 active points

So, would I only get to use 30 points of STR to add 2d6 to the HKA for a total of 5d6?

Or since I did not buy explosion for my STR, do I not get to add any STR to this HKA? If this is true, Should I just buy it as an Exploding RKA with no range?

See the rules for adding damage on 5E 270-72. IIRC the info you want is primarily on page 272.
