M1550R grains don't fit in liner . . .

[DMcCauley]

Anyone else have any problems with the grains of a 75mm motor case (Aerotech) not fitting the liner?

Trying to build this motor now, and the grains go in about 1 inch and then are stuck. Not sure what to do. I'm certaintly not in the mood to sand the grains right now to make them fit nor am i certain thats even safe with the heat generated from sanding.

Ugh!

Peel the outer glassine layer from the grain tubes and they should fit fine.
