RE: Triple 7 question.
Are you cleaning the bore completelybefore each shot?
You may find that loading the SST/Shockwave on a clean, dry bore is much easier.
Also, you may wish to invest in a range rod if you have not already done so. Loading life is much easier with a range rod. I don't go to the range or hunting without one. I carry a collapsing range rod for the field.
