7x47 Build

[Shinycat]

Hi all
What's everyone's thoughts on building a 7x47 ( with straight wall and 40 deg shoulder which is standard ) in a tight neck of of .30765" and a freebore of .188" in a 28" 1:7.5 twist fluted 1.25"straight profile barrel. The action is a trued and sleeved Rem700 with a Jewell BR polished trigger.

As long as you make it use the 6.5x47 dies like the 6x47L does it may catch on. Therefore dont change any body dimensions except bore size.

Here is a read for you. 6.5x47 lapua is a 30 degree shoulder.

I just got a reamer in to do just this on a Tikka hunting rifle build. I'm actually pretty excited to see how it turns out. Should make a very fine hunting round that has every chance to be a very good shooter.

If you are talking a 7 x 47 imp. If it is, dies are no problem, use a Dasher die open the hole for the neck size and use the correct bushing. If you are talking a 30 degree shoulder do the same with a BR. die……… jim

Honest question- what would the advantage be over a 7mm-08?

Thanks Drop Port
I found the article and was a good read.
A friend ran my spec's through quickload and got these results.
162gr hpbt with 39.5gr of Varget out of a 24" barrel produced 2642fps.

A better designed and more efficient case,you can have small primers 7 08 cases by necking down 308 Palma Lapua cases.

Do a 7mm08AI. More MV and less pressures when using Palma Brass. Works awesome. And very accurate.
