300wsm

[Biscuit]

Anyone know if a 300wsm Winchester model 70 with sporter barrel can be threaded?

send the gun off to be magna-ported

the 264wm pre64 sporter i have seems to thin for that, so possibly less material on the 30cal

Has to do with available metal thickness. What is the Mzl diameter of your barrel? The general guideline most smiths use is min of .550 but better at .600 for a bigger calibers.

should be around the .640 mark, but could be less. most won't thread 1/2's on anything larger than .243. 5/8 (.625) would be not ideal @ .600, but might do 9/16 which can be common for 26-28cals (depending on makers).

You are doing 1/2x28? Bolt guns usually spec 5/8x24 - unless you have a can that you wanna swap back and forth...cool

.640 should be plenty.

i would need to measure the 1 i have to be sure, but .625-.640 is where i remember, but it's been 10 years since then. cutting 1/2' threads only leaves .077" of meat on the barrel.

Weatherby does 1/2 28 on their Ultra Lightweights in 300Bee and 308.

I had to do 1/2-28 on my Howa 1500 and then an adapter to 5/8 for the Brake.

 

[SecretSquirrel38]

I am going to have this done on my 30-06.

Witt Machine and others make a clamp on brake if you wanted to go that route.

Just say on call tv where silencer central threads barrels for like $35 call them. They should be able to tell you if they can do it

Yeah I checked them out. It's more like $160. But includes shipping both ways. Probably the route I will go!
