So , the guys are cutting their top cases for full skirted pistons .

Q1 : what will the new pistons be ?

Q2 : If the piston skirts are cut , what is the benefit of cutting the top case ?

I have new barrels now with new cast pistons and will be installing them soon , after they have been ported .
I had a problem with my earlier 300 barrels being nicasiled and scoring after 5 mins of running - waiting to hear if i did a mistake or the nicasil was a bad job .

Thanks , Neal
