I've used those bullets quite a bit with 303B, 7.62x54R, and even some 308 loads. I find they are so short I get feeding problems. In my P14 and Mosin they need to be guided into the chamber with my fingers because they have a tendency so just slam into the back face of the barrel. I use pure WW, water dropped, and they mic at .3145-.3150" with a vernier micrometer for me.
They've never shot well for me with pistol or shotgun powders, with or without fillers. They seem to work okay with Trail Boss. Maybe the load density helps with consistency?
