All things being equal roll crimping should reduce pressure of a folded crimp recipe by 500 - 800 psi on average. Roll crimping is slow, if you don't get them real tight you will experience more squib loads, you will get fewer reloads out of hulls as roll crimping is harder on them. A short kit for a MEC 600Jr sells for $24.99 through Cabelas and I didn't shop around. Shooting a 2 7/8" 10ga double is excuse the expression, big fun. You can turn out shells a lot faster using a press to fold crimp.
