    How scarce is the edge brass or can it be made?What kind of fps are they getting with 200 and up projectiles?

    Of the mainstream; 338 lapua and the 338 Rum or 338 edge are all real close in performance, obviously the rum gives a little up in velocities.

    Lapua brass is about $230 per 100
    300 rum brass for the edge is about $85 per 100
    338 rum brass I can't say for sure but probably in the $80-90 per 100.

    The 338 win mag would be a step down from the above, This is a good round and if your not intrested in launching 300 grain bullets, it is probably a reasonable choice with bullets of 250 gr and less. I would guess that brass is running somewhere around $60 per 100.

    Not much else is mainstream, 338 federal? 338-300wsm? 338 Allen mag?

    The 338 Edge is the 300 RUM necked up with no other changes.
    The 338 Lapua and the 338/378 Wea. are both factory loaded rounds. I went with the 338 Lapua because of the brass quality of the Lapua made bras. 338 Lapua bras made by Norma or Hornady will cost less than the brass made by Lapau and the quality and strenght are reflected in that cost rduction.

    338/378 Wea. Brass is made by Norma. Norma brass is very good quality like the Lapua brass but a bit softer and thus not as strong as the Lapua brand brass

    No, the 338 RUM brass is shorter than the other RUM cases. The 338 Edge is the 300 RUM case necked up to 338 caliber with no other changes to the case dimensions. Not a reformed 338 RUM at all

    338 AM is ~ 500 fps faster than 338 Edge/338 Lapua with the 300 gr SMKs.

    The 338 AM is in a different league compared to the Edge & Lapua & RUM.

    Yes it is and it's based off of the 408 Chey Tac case not easy to obtain and it is expensive.

    The 300 win action magazine will need to be lengthened for the 338 Edge or Lapua. and is most certainly not suitable for the 338 AM

    The magazine well will have to be opened up for the 338 Edge and the 338 Lapua. The action is not suitable for the 338 AM that round is based off of the 408 Cheytac case which is based off of the 505 Gibbs. It require a larger action
