Can somebody explain to me the necessity of the 338 Edge if the 338 RUM is essentially running the same numbers? And why is the Edge necessary if you can get the same speeds with the Lapua (actually better with the same loads)? I understand the 338 Norma because it is developed for short barrels (22" to 26") but why the Edge? Sorry Shawn, not knocking your dream child. I think it is a cool idea, but some explanation please. I'm failing to see the benefits of this caliber. Please be kind, just thirsting for knowledge.
Tank . I think the Edge was developed before the 338 RUM was brought out by Remington
and proved its worth as a 338.
Remington came out with the 338 RUM because of all the demands for a 338 and later even
came out with the 338 Lapua for the same reason.
As to the 338 Edge; It has slightly more powder capacity that allows the use of slower powder
with "BIG" bullets if used in an extended mag. If you place a 338 RUM in a extended mag you
can seat the bullet longer and gain almost the same powder capacity.
The Lapua has slightly less powder capacity but can be loaded harder because of the fine
brass and still hold up.
The only down side to the Edge would be the slight neck thinning if the 300 RUM brass is
used but the 375 RUM is the same dimension and if necked down the necks are thicker.
Also the Edge is a wildcat and factory ammo cannot be bought.
All of the big 338s can be very accurate and I see no advantage in one over the other under
equal conditions ,Just ones preference.
This is my take on it and I hope it helped.
