338 Edge/Lapua Detachable Mag Length?

[shooter981]

Does anyone have a detachable box mag from either HS Precision or Wyatts for the 300 RUM or 338 Lapua and could tell me what OAL round would fit in the magazine?

3.650" OAL will fit the HS, 3.700" is what mine measured inside. I dont know if it will funtion at 3.7" hope this helps

I have the Seekins detachable box magazine and it will accept a 3.9 inch overal length

use the seekins for either one of the cartridges you mentioned.
