Peterson 243 versus lapua 243 neck thickness

[mgdietrich]

I am using blue box lapua 243 brass, it appears my chamber neck diameter isn’t allowing the lapua brass to release.

does anyone have both lapua and Peterson small primer 243 brass to compare the neck thickness on? I would like to avoid turning necks if I can.

thanks!

The neck wall of a new brand Lapua brass 243 .0155 and the Peterson 243 SRP .0145 . Two weeks ago ,I tried Peterson 243 SRP for an elevation
test at 300 m and I was very surprised ,they hold 12/15 mm (1/8Moa) ! I loaded with N 160 ,CCI 450 and a Bart Hammer 105 grs .
Hope this will help you.
