Dimensions of Petersen 6BR and 7BR Brass

[jackieschmidt]

Do any of you have the dimensions of the Petersen 6BR and 7BR brass, to be exact, the overall length and the average neck wall thickness of each?

Will check the 7 br today Jackie! Allen

Overall length averages 1.510 to 1.511 with most 1.510. Neck thickness averages .012 to .0125 with most .012 for the 7br. Allen

Thanks.

I wanted to try the 7BR necked up to 30BR, but they are too short, as my reamer uses a trim to length of 1.540.

Is the 6BR 1.560 like the Lapua?

A random check of ten 6BR cases measured 1.552 to 1.554. Only one case measured 1.554
