First of all I like powerbelts except for the cost,The skirt is nothing more than an attention getter, The bullet works because it obturates (SP)
it has too toengage the rifling ,the skirt turns on the pedastal so it doesn't do anything or very little to help rotate the bullet orto seal gases, it does keep the bullet on the powder tho, I tried them without the skirt and they shot the same,
