6.5 weatherby rpm

[ZReed85]

Anyone know how long a weatherby 6.5 rpm is with a 156 Berger to the lands of the .188 match reamer?

Thanks!

That is going to differ on every rifle. Nothing is perfect in this world. You have to measure it yourself, or you might have been able to have your smith do it when they did your barrel.

I understand it'll vary .01 or .02 with any decent Smith, just looking for a ballpark.

Thanks guys!

If you have a fired case you can soft seat a bullet to find the lands. It takes about 3 minutes to do it

I'm trying to determine what mag box is needed.

Don't want to buy a defiance with a standard 06 if a wyatt's is needed

I have a 280 ai with a match chamber that won't fit into a standard box. I have also been interested in the rpm. Can't wait for a 25 rpm.

berger 156 =3.549
153.5 =3.532
144 =3.526
now depending on throat angle and how accurate bergers numbers are those numbers might be off 0.10-.020 thousands

Thank you! I was just wanting to make sure a 3.6 standard box would feed with room to spare on the 156 with .188 freebore
