380 Cast bullet weight safe?

Hi all,

I've been using the Lyman cast bullet manual for loads - been using the 102 grain recipe for 380 rounds.

I've recently cast some bullets that were a little over weight - 105 grains.

I'm using Unique, the min/max for a 102 grain cast is 2.9/3.3

I've got my powder measure set up to drop 3 grains, but many times it'll drop up to 3.2

Given that information, does dropping 3.2 grains with a 105 grain projectile give you the willies and want to back off or do you think the additional weight on the projectile won't make much of a difference?

Appreciate your insights!!

zhughes.  It's not enough weight difference in the bullet that I would worry about it. Just my opinion. Commercial bullets vary that much at times. Gp

GP is correct, nothing to be concerned about.
