300 Win Mag - Magwell lengths

[BearNaked]

Figured the reloading page was the best spot since I will be reloading this round. If I am using one of the 210-230 gr bullets, is it worth getting the CIP magwell for 3.850" mags or will the standard 3.715" magwells for 300 WM suffice? since I am still in the early stages of the build, I want to make sure I am covered if I need to seat the bullets longer than expected.

Probably if you tell us what action your using we could help.

Agreed, the action will ultimately dictate how long you will be able to run withholding any mods are done to the feed ramp.

sorry guys. been out for a bit.

it is a Remington 700 long action. I would assume the magwell on the action itself would more than likely have to be modified, right?

I could measure my Rem 700 long action to see were the limit is if you like but would assume it will be on the short end of the spectrum considering my short action is pretty short as well.
The Kelbly Atlas Tactical I have (short action) seems to be optimized for even the longest COAL mags I have available which are Alpha using the Grayboe Renegade and MPA M5 bottom metal with the feed ramp being basically flush with the mag port.
Seems pretty well thought out for its intended purpose and would think the long action would be as well.

Measured my rem 700 long action with BDL FLOOR plate and looks to be 3.7" over three different measurements so give or take .050" but pretty accurate considering the feed ramp is flush with the magazine box. FWIW

Thanks guys. I think I will just stick with the standard length.
