300RUM to 338 EDGE then back

OK, guys here it is... Right now I have a stock 300Rum sendaro. Now I want to remove the barrel and screw the Edge barrel on which was a stock 338Rum Shawn reamed to the Edge.

The only difference is when Shawn fitted the Edge barrel to the reciever he used a Tubb oversized lug, which I just purchased another.

The way I see it is I take the Rum barrel off and screw the Edge barrel on using the oversized lug check with the go no go gauge and any mods do it to the barrel not the reciever and basically be able to make the swap pretty easy. What say yall.

Also what are any recomandations of a barrel vise besides oak bords and a vise, and what is the best lug jig.

Thanks Tim

you are on the right track you just relieve the shoulder the correct amount for the thicker recoil lug and the rest stays the same.

Cheers Bill

Re: 300RUM to 338 EDGE then back

You will have to mill the stock for the wider recoil lug as well.

I would recommend the Brownells barrel vice with aluminum shims. YOu will find the taper on the Rem factory barrel a bit of a pain in the rear to get a good grip on if it is tight in the receiver. YOu can have a set specially machined to match the taper on the barrel which would be best or you can make a set of shims using acraglass of marine Tex. You will need something to grip that taper of you will just marr the hell out of that barrel and get nowhere as far as taking the barrel off.

I also use the Brownells receiver wrench and they also offer recoil lug indexing jigs. WOuld be best just to have the lug pinned though.

The best barrel blocks I have found for the Rem factory barrels you have to make, I cast them out of lead, it grips really good and can be made to fit the exact taper of the factory barrel, like kirby said they can be a pain.

I have one of these. You want, I send......

Will keep me from being tempted to use it...again. [img]/ubbthreads/images/graemlins/blush.gif[/img]

As Kirby and Shawn, it can and will be a pain.

Shawn/Kirby: Is there any real reason for all that torque when installing a fitted/trued barrel. On samll cals( 222/222 Mag) I have just "snapped it" on by hand. then used the vise & wrench to remove??

Hey Shawn, can you describe the method of casting those lead jaws inserts for removing factory barrels? Curious minds want to know. [img]/ubbthreads/images/graemlins/grin.gif[/img]
