Suppressors which rifleing in a bartlein

[tjonh2001]

i am building a new 6x47lapua that i will be trying to shoot 105 bergers out of. i am buying a 1-8twist bartlein and i have the option for a 5r or a 4 groove. wondering which would be the best for this project?

I don't know what is truely better , Kreiger has set a bunch of records with 4 groove barrels , some say that the 5R's are faster , I have never been able to get one of each from each caliber and chamber the same to see if their realy is a differance.

All the 5R's I've had all shot as good as any of the 4grooves I've had
