I have a new to me Husqvarna Roller that I would like to feed a light load of smokeless under a lighter projectile.
I want to PC, so I will not be using the lube groove, but I want some place for the lead to be able to flow when getting squished into the .476" lands.
The historical bullet weight for this cartridge was in the 385 grain range and several have said 350s worked better. I only intend to kill paper, so weight is of no advantage to me. I really could not find a 350 that I liked as much as this 320.
The bore measures .509x.476", almost hexagonal.
I am considering this Accurate mold;

1) Is there an issue with having a projectile that has shorter bearing surface than bore size?
2) Am I really going to see an advantage with having the large lube grooves to allow the lead to flow?
3) Any other considerations that I should be thinking about?
Thank you for your help, Tim.
