Unit 6/7 early season is little different as 6 is above timberline and 7 is within Rawah Wilderness Sept 3-Sept 11. When they did unit 6 early Sept 26-Oct 4 they used E2-R. If you look at early Sept 3-Sept 11 unit 14,16,161 Mt Zirkel Widerness when they did Early Sept 26-Oct unit 16 it's E1-R.

Lot of good ones Bartlein,Mike Rock,Broughton,Brux,Kreiger,Lilja,Hart are some of the ones I'm shooting. It may not be who's barrel I want to use but what barrel can I get. I would get hold of gunsmith you plan on using and see what he can get.

If you read the details on matrix 7mm bullets they list 3 different types and first two are hunting bullet and the VLD are match quality using J4 jackets and they list 1/9 twist. I would guess their using same length jacket as 180gr and Berger makes two jackets one for hunting other match might...

I reload for my varmint partner's T-3 in 300WSM and it's very accurate rifle. I much prefer rifle without a removable magazine in fact none of my elk/deer or antelope rifles have one.
