338 edge & 338 lapua

Please be easy on me I'm new to these big 33's. what is the difference between a 338 Edge and a 338 RUM. If I was going to rebarrel a 700P should I use a 300RUM or 338 RUM ? Could I rebarrel a 700P 338RUM to 338 lapua. which is better 338 Edge, or 338 lapua?

    The 338 edge is a 300 rum expanded to 338, which is .100" longer than the 338 RUM
    The 338 lapua will fit in the 700 action but you need to use a sako type extractor.
    Which is better? have no idea, the lapua brass is stronger, more consistant, but also more expensive if it were mine I'd go 338 Allen Xtreme, a 338 lapua imp. so to speak.

    Here are some really short answers (lot of discussion of this subject in the search area),

    Edge is about 1/10" longer than the RUM for an increase of around 7-8% capacity increase. Maybe 80-100fps increase with heavy bullets (300gr) and long barrel 28" or longer.

    the Lapua and Edge have about the same performance, but the Lapua needs a larger boltface and in my opinion needs a bigger action (more $$$). The Lapua has better brass available.

    Will the 338 RUM handle a 300gr SMK? If so that looks like the poor mans way to me.

    What is your opinion based on re: needing a bigger action than the M700 for the 338 LM ?
    My M700 338 LM seems to work just fine. What am I missing ?

    It is only based on the amount of bolt shroud around the head of the cartridge. It is my opinion only, that's why I underlined and italicized it. I'm not a gunsmith and I know the Rem 700 is used all the time. If/when I get a 338Lapua, it will be on a larger action. No harm intended.

    AJ has excellent advice. Performance wise you or the animal will not know the difference between the three. I would go with the one I could get into the cheapest. They are all very accurate. AJ is right on the money with the 700 action. I would do the ultramag because it is a much better fit for your action. I have all of those and enjoy shooting all of them. This is what my guns will do so you decide. 300 ultramag with 200/208 grain with .588-.675 high BC bullets get over 3200 fps. Very good long range performer. 338-300 ultramag with 300 matchking at .765 bc or whatever it is will shoot 2750-2825 fps with best accuracy. I shoot the 225 accubond .550 bc now for best results at 3325 fps. If I shoot the 300 I go to one of my big 338's that will push the 300 faster. My 338 lapuas will shoot the 300 matchking at 2850 fps and the 225 AB at 3375 fps out of a 26" barrel. The others are 28". Of these the 300 ultramag is probably the best shooting rifle out to a half mile and will kill anything. The 338's will just knock the absolute P out of stuff though.
