Let me modify that a little bit:
衝撃力 = Impact Force
発射速度 = Launch Velocity
爆発衝撃 = Explosion Impact
爆発範囲 = Explosion Area
対反動性能 = Versus (Anti?) Recoil Performance
As for the optimal range... well, security in this case meant assurance, so I would say that the speculation is accurate. Then again, your translation may be more accurate in the context of AC.
As long as it's not hiragana or katagana, I could help with the translation, so bring on the screenshots!
