Hey how's it going, well I have a project at the gunsmith and need some load data.
The rifle consists of a 7mm wsm chambering with a 1/8.4 twist 27imch varmint contour barrel. I am using a badger drop box mag so that will be my mag length.
My question is I'm curious what kind of velocities I can expect with three bullets.
I'd just like to hear what kind of velocities you all are getting with a similar combo. I also would like to know your load so I know what I'm looking at for powder and bullet set up. Thanks for your time
I use 1:9 twist on most all the 7MM WSM I build and generally speaking with 180 bergers we are getting 2950-3000 with the Wyatts box giving us that .100 extra powder space.
This has been one of my most popular builds over the last year for all around hunting guns.
I would really like to get some h1000,retumbo,7828ssc loads. Retumbo has me curious because of the velocity gains. But I also like the 4% extra case capacity of the 7828ssc so any loads of either would be nice.
