Also, what do you all consider to be a good barrel length and twist rate? I plan on shooting the Berger 300gr vld or the 300gr SMK.
in terms of converting to 338Edge, there's nothing you need to do with your action
Both the 300WM and the 338Edge use the same size bolt face, so no alteration to your bolt is necessary.
SAAMI spec COAL of the 300WM is 3.340". I am uncertain of the SAAMI Spec COAL of the 338Edge although the 300RUM is 3.600". With most longrange custom rifles
, the barrel is custom throated (longer than usual) so that you can seat the bullet out far enough so as to be able to take advantage of all the cartridge capacity for powder. As a result, many longrange rigs are single shot rifles. An alternative would be to have a Wyatt's extended magazine installed. This would probably strike a balance between SAAMI spec and a long throat. Hope that makes sense.
no less than 28" and no need to be longer than 32". One consideration on barrel length that has nothing to do with ballistics is carry-case. A Rem700 long-action with a 28" barrel with a muzzlebrake will just fit inside a 'standard' case. I have a 300RUM with 32" case + muzzle brake
and had to get a different case for the cannon.
