Yes compacting the powder can raise pressure. Are you talking about Remington pointed Soft Points? When ever you start to load a new bullet (or any new component) you SHOULD START LOW AND WORK UP. using an empty ,unprimed case, start the bullet just into the case. Try it in the chamber, then adjust the seater a little at a time till you can just close the action with out forcing it.Then you can make a final adjustment to get the SEATED bullet about 0.030" from the rifling. Using a bullet held against the neck, you can see how far into the case the base of the seated bullet is. The Handi rifle is NOT held to the same over all length as the lever and bolt guns are. It is not a very strong action, so be carefull of using over pressured ammo. I am wondering where you got "MID RANGE" loads for a 180 grain bullet in the 30-30!!
