Quickload variants of 300 Win Mag, what do they mean

[AI Perfector]

Hi, I'm using Quickload's data for my 300 Win Mag. It has five options for that cartridge, i.e.

300 Win Mag (@)

300 Win Mag (F)

300 Win Mag (N)

300 Win Mag ( R )

300 Win Mag (W)

What is the difference between them? Thanks in advance.

I think

F = Federal

N= Norma

W= Winchester

As case volumes vary.

Not sure of the other 2

I use the W setting as I have Winchester brass and it seems to work Ok

Cheers

Yup, I thought that may be it. The R that looked like a Registered Trade Mark should have read just a simple "R", which could be Remington. I've now edited that one in the original post.

Any other ideas,..... or contributions to the @?

Perhaps @ is an average setting?

As I said I've not had any problems with using the W setting with Winchester brass.

Cheers
