300 WSM Reamer specs?

[James EPS]

I am doing a 300 wsm build and need to get some advice on reamer specs. Anyone have reamer prints they would like to share that would be great. I am going to build several rifles from hunting to 17 lb bench rifle. I will be using bullets in the 180-220gr range plus I have a 30 cal throater so I should probably spec a freebore for light 150gr er's then I can throat accordingly.

Any suggestion would be great.

Thanks
James

Thanks John

What are the standard neck on win and norma brass?

 

[mr45man]

The win brass is about 337 loaded.
Norma a tad bigger at 338.
Thats with the brass i have.
Before ordering a reamer i would get my brass first.
A couple hundred, measure and decide if you want to skim the necks.

John,
Thanks for sharing your print and information.

The one I am running currently is a 341 neck (no turn for the nosler brass). I don't remember the FB but I asked for it to be throated for the 190 bergers when I ordered it from pacific. My friend runs a .338 neck with (a lot of freebore) he can't find the specs lost them in the loading room.

I have a .338 neck and you can completely clean up the Norma brass when you turn. Mine has a .200 freebore and it is almost too short for 210 VLD. Probably good for 180 to 190 VLD's. Matt

I believe the one for the 210's is .235 but not 100% on that.

 

[dkhunt14]

Yea I believe your pretty close on that .235 Because I told my buddy if I get a new reamer for the 210 I would get it throated out another 30 thousandths or so. Matt

 

[dragman]

if you go with that the .215's will just make it to the lands the 210's and the 208's work good.

I appreciate the information guys. I have a 10 twist barrel here I have been kicking around for a while and I think its time to WSM that baby, ha. I am going to be making my own bullets so free bore shouldn't be much of an issue. Ill prob end up short on the reamer for 180's and Ill use my throater to clean up any chambers that want long heavy 30's. Ill prob do a .338 nk also that sounds good to me.

Thanks
James
