.329 bullet in 8x58R Danish

[gunboat57]

I'm getting back into reloading for a rifle which has .320 bore and .330 groove diameters. It's a Swedish rolling block in 8X58R Danish. It seems like a standard .323 jacketed bullet wouldn't have much rifling engagement. So I'm going to try 150 gr .329 jacketed bullets. If I keep loads on the mild side, would there be a problem using these bullets?

I already shoot .330 cast bullets out of this rifle.
