A little project I've been toying around with for a few years needs to be concluded.
I have a fair amount of 452's and 458's - so please no recommendations of other firearms.
The cartridge is my own design, and will be chambered in a Remington 700 SA as a single shot with a new bolt will be ordered from Pacific Tool.
Now I need to to consider type of barrel for best accuracy.
Barrel: 18" long in a medium - heavy contour.
Bullet: .458 hard cast weighing between 300 - 325 grains.
Velocity: 1708 f/s ( There is a reason for that, plus I like that number.)
Any experienced suggestions for the questions below is greatly appreciated.
1. What make.
2. Type of rifling cut.
3. Rate of twist, or any other suggestions
Thanks
