Sierra MK Jump/Jam Info

[eshorebwhntr]

I've primarily only used Bergers since I've been reloading. All my rifles have shot best with minimal jump with the VLD and I've had good luck.

I'm loading up some 190 SMK's for a buddy in his 30 Hart. What is the rule of thumb with SMK's? (if there is one) Do they like jump, jam, impervious....?

Thanks in advance for the help.

There is no more of a rule of thumb for SMKs as there ever was for VLDs.
But I'd recommend Berger's seating depth tests with ALL bullets.

SMK's are very forgiving. I would start at .015" off and let them rip. With the tangent ogive they are very jump tolerant.

Makes sense. Hopefully we'll have an answer after this weekend.
