Re: Berger 140 Hunting VLD at 3,500 fps?
The 5R will help, the twist rate won't, the most help will be shooting the 140 Target and not the Hunting. They may live for a while but when your throat starts getting rough, which will be soon, you'll start failing jackets. I've found pretty much 3250-3300 fps will be the top limit with the Hunting and even there you'll have issues when your throat get rough.
If you idle the 26 Nosler you might as well shoot any number of rounds that will run a 140 with less capacity, less powder and more life!
