7mm-300win mag or a 7mmWSM

[coupalr]

Here is the deal it is time for me to rebarrel my 300 win mag. I have decided that I want it to be a 7mm but don't know which case to go with. The action is a Rem 700 LA and and I already have a Redding Competion Die set for the 300wm so I could just change the bushing to neck size the 300wm brass down to 7mm and I already have lots of 300wm brass, so I am leaning towards the 7mm-300wm but the success that many guys are having with the 7wsm has got me wondering. What are some of the opinions here?

go the 7mm300 as most of the competition shooters are going that way as they have a longer neck to align the projectile as you already have the dies if you have a Redding Type S sizing die you only would have to change the bushing and you would still need a seating die but a 7mm competition die will work fine.

What is the difference between the 7mm-300wm and the 7mm Rem mag?

7mm Rem mag is 2.5" long and the 300 win mag is 2.62"long.
I am going with the 7-300win mag.
