Converting a .338 RUM to edge

Hey guys,
I have a remington 700 LH in 338 Rum and I would like to convert it to .338 edge what steps do I need to take to make it happen? If it is possible.

Thanks

Re: Converting a .338 RUM to edge

Put a 338-300 RUM reamer in it will take care of the barrel part. Then you will need to make some modifications probably to make it a repeater with the slightly longer case. But why would you want to go to the trouble? There are some smart people at remington that tested this thing extensively and made a good decision with the 338 RUM for the standard rem 700 action. You are going to cause yourself a good bit of trouble and expense and end up with a rifle that does the same thing and serves the same purpose.

Re: Converting a .338 RUM to edge

Please correct me if I am wrong. Reasons why I would want to change are

1-the edge is cheaper to reload in that it uses less powder for same results.
2-it has less recoil resulting in better accuracy
3- the edge can shoot up to a 300gr. bullet where the Rum is only recommended to 250 gr.
4- Slightly higher velocity on equivalent bullets and loads
5- Slightly higher energy on equivalent bullets and loads
6- Considerably higher Ballistic Coefficient when using the 300 gr. sierra match king

I know all of these are subject to load. I am still trying to gather all my facts any help in correcting me or expounding on what I have stated would be appreciated.

thanks

Re: Converting a .338 RUM to edge

1. edge is more expensive to reload
2. same recoil
3. both shoot the 300 SMK with equal effectiveness between 2700-2800 fps with best accuracy out of your factory 26" barrel.
4. May or may not get higher velocity but it will not make enough difference to make a difference if you do.
6. both shoot the 300 SMK just fine and use the same accuracy loads of 91-92 grains of H-1000 or 95 or so grains of Retumbo.

If your 338 RUM barrel does not shoot the 300 grainers well it will not shoot them any better with the 338-300 RUM.

What you will find is dies will cost quite a bit more and you have the process of necking 300 RUM to 338 caliber. Also the slightly longer 300 RUM case is going to cost you to modify your action and buy a new magazine to make it a slick repeater. It is very popular and many people do it to shoot basically the same as my 338 RUM. I built many 338-300's until 2001 when the 338 RUM came out. Now I hunt with my factory 338 RUM if I use the RUM case in 338.

You are better to keep what you have or order a custom barrel if your does not shoot well. Then you can make the decision whether to further customize your rifle to fit the 338-300. I chose to quit doing the wildcat in 2001 and shoot the factory round. Others choose differently.

I am not the guru and others have other opinions but that is what I found.

Re: Converting a .338 RUM to edge

Yes, seriously that is either stuff I have read or been told. The only correction that I need to make was with the first point being cheaper because I was told the brass price was the difference being the advantage to the edge because of the brass you can use, but it requires more labor.

I think for now I will get a good scope, a good barrel, a box a shells and have some fun.

I do appreciate yall's input and for now I am going to go see what it can do at the range.

Thanks
