300 Win Mag bushing size

[rob221]

I've got a new 300 Win Mag. Have Redding dies, and wondering what loaded Winchester brass measured. I need to order bushings. Can anybody help? Thanks in advance.

From memory, can check later, I was using a .335”-.338” bushing depending on bullet used.

Cheers.

Loaded Winchester brass .336 I use a .334 bushing. if I were you I would avoid win brass after weight sorting a bag of 50 there was a 10 grain spread on weight. 30 were with in 2 grains out of the thirty 6 had some bad creases on the neck. so ended up with 24 to prep not worth it. picked up a bag Sig Sauer for the same price as Winchester and was surprised at how consistent they were for weight 1.5 grain spread for all 50 pieces. this was for my hunting rifle. also using .334 bushing on Sig brass.
