[URL= ]Black Beauty[/URL] Received some Vit 160 today.I have some Winchester cases on hand and some Norma cases on order.I will be testing the 140 grain TSX at 200yds.I will be useing Wilson dies to seat and necksize.This is going to be fun! Anyone have the correct neck bushing size for this caliber?

You'll have to measure your existing brass to determine neck bushing size. You may end up with a bushing for the Winchester brass and a bushing for the Norma brass. This is the advantage of neck bushing dies.

By existing brass do you mean a loaded round,if so I have none on hand.I have a feeling this cartridge is going to be more difficult for the neck to get a good grip on the bullet.What I did to determine a bushing size was to take a new case from a cartridge that I was familiar with measure its neck diameter and and compared that to the size of the bushing die I use.I then used this same diameter difference and subtracted it from a 270WSM case to get a bushing size.I ordered a 304 and a 303.
