7PRC - Hornady Head & Shoulders??

[Charlie-NY]

I am just starting to set up my dies and equipment for a new 7PRC which will be picked up this Thursday. I have the Hornady Head & Shoulders gauge for setting up the headspace. Just wondering if anyone knows which is the correct bushing for the 7PRC. The 6.5PRC uses the E420 bushing but the 7PRC may be different.

Anyone know?

Appears to be the same as other standard boltface magnums

The 6.5PRC uses the E420 bushing but the 7PRC may be different.

As @SKWERLZ shared, it takes the 0.420 bushing. I acquired a Whidden case gauge along the way. Didn't think much about it at the time. Then I put a go gauge in it, and it read 0.00. Since then, they are my preferred method for measuring shoulder set back.

Thanks for the feedback. I just checked a load of Peterson brass to get a baseline. Hopefully the new chamber will be close.

I like to get 2 firings on a case before having a modified case made for my rifles. We'll see how things go.

I did a double take on the header. Sounded like Hornady had got into anti-dandruff shampoo..

When I bought my set some years ago, that's the name used by Hornady (Head N Shoulders). I think it was renamed to Headspace Comparator, or something like that.

Yup - that's the bottle that my Hornady tools came in. You must have the same set. LOL

I would love to hear you guys report on the 7PRC. Is it going to be the favorite of the PRC lineup?
