Now that the 225 Win is ready to test - 03/04/19
I made up 200 60 grain bullets made from rimfire cases.
When you use rim fire cases as bullet jackets, it's important to clean them up and sort them by headstamp. RF cases weigh from about 9.3 to 10.5 grains, depending on the brand and case size. These are SK Jagd cases that came from an indoor range.
They say that bullets using RF cases shouldn't be launched at more than 3200 fps. I will keep velocities pegged there. The 225 can push 60 grain bullets from 3400 to 3500 fps.
