7wsm or 7mm/300wsm

Alright guys im fixing to order a new barrel in one or the other which do ya'll think is the best all round accurate choice, the 7wsm or the 7mm/300wsm.

Lets say the majority goes with 7mm/300wsm, will regular 7wsm dies work or not. Seeing as how i've already got 7wsm dies.

I know from what ive read the 7mm/300wsm is made off of the 270wsm or the 300wsm i've also got 100rounds of new 270wsm brass.

But if ya'll think that the 7wsm is the way to go thats good too, just curious what the rest of you guys thought.

One more thing what barrel length would ya'll go for i will do most of my shooting at targets 70per. of the time so weight isnt a big issue for me.

Thanks
Nathan.

Re: 7wsm or 7mm/300wsm

7mmWSM dies will not work. The 7mm has longer walls and a shorter neck.

I would vote that you go 7mmWSM since you already have the dies. You can also use the 270WSM brass, just takes a little fireforming.

That's what I'm doing with 270WSM Norma brass in my 7mmWSM.

The only thing you are loosing is the neck length. Serious bench guys would rather have the neck length than the capacity. I'd rather have the 50fps.

+1 for the 7mm WSM.

nddodd,

I have had both the 7WSM's and the 7-300WSM's my personal pick would be the
7-300WSM, for a few reasons.
1- a longer neck for more bullet support when used as a repeater.
2- very easy use of Norma .270 brass

As far as dies you can use a Redding type S .270WSM full length sizer, with a .312 neck bushing, with no alterations and a 7WSM seating die can be used with no alterations, but I do like to shorten the bottom of the die to accommodate the shorter head space.


Things to ponder though as the 7-300 is not for everyone

1- A 7-300WSM will chamber in a .270 WSM factory rifle..BAD THINGS WILL HAPPEN!

2- No factory ammo available


it will definitely be the 7-300WSM for me as I like as little brass prep as possible and the longer neck.

Just my $.02
