6mm BR chambered for Remington Brass

[richard295]

I have a barrel in 6mmBr for XP100 that was chambered for the Remington brass rather than Lapua Norma brass. The difference of .006 in brass,off the base dimension)is such that Lapua won't fit the chamber. Question is what body die do you get for the slightly smaller remington brass. Would today's 6mmBR in small base size the Remington shell back to .4643 or would it size to the Lapua .4703? It would be nice to be able to squeeze the Lapua brass down to the Remington spec? It that is not possible, then the next step would be to get the right body die for the remington brass?

I would not know where to get a 6BR REMINGTON die verses the 6BR NORMA.You may want to look in to having a smith run the proper reamer in the chamber or a total rebarrel job.
Perhaps someone else will chime in with better information on the dies.

I just checked and Redding has the Remigton version in their series B dies and the Norma in their catagory I. Sinclair International has them listed

See my post over on the "other" forum. I think a simple polish job is the easy way out.

Ray . . . I had to edit . . . math was wrong
Remington is .006 smaller which translates to .4643 compared to Lapua .4703.
Do you think I could polish out .oo6?

Unless she is a real shooter, why not just re-chamber it for Lapua brass. You'd be further ahead IMO since you would have better brass. Less forming, more shooting.
