Best 338 Lapua reloading components

I am getting a custom 338 Lapua built, which will be finished later this year. So in the mean time, I am pooling reloading components. I just purchased 4k federal 215m primers(got the email 10 minutes after Midway recieved a shipment) and some Lapua brass. I've been looking at various dies and any input would be great. Also, I would like a powder that is proven accurate with this round without being too affected by temperature change. I know the magnums have a shorter barrel life and have decided to go with the SMKs. Would the 250s wear the barrel less than the 300s? The barrel will be a 1 in 10" stainless Lilja. I'm not planning to take this round out much past 1500m. Any load info and suggestions would be appreciated.

    I am having very good performance with H1000. I would certainly try that in yours. Find some MRP2 also, that is a go to powder in the Lapua for the ones who know it.

    If you are really worried about barrel life, get the barrel melonite coated. Go to BR central or 6mmbr.com and search for the threads on that process and the long barrel life it is giving. http://www.benchrest.com/forums/show...lonite+coating

    I am fixing to break in a 338-408 and when done, that barrel and a barrel for a 338 Lapua Ack Imp are going to have it done.

    Redding Bushing "S"type dies.

    CCI 250 primer

    H-1000 powder ( start at 89 gr and work up slow)

    300 SMK and mine like to be about .060" off the lands.

    Sapper,

    Several folks here have already mentioned the H1000 and it's an excellent choice. I used to use that as a standard accuracy powder for daily QC firing with both the 250 and 300 SMKs. You should be able to get somewhat better velocity and still have first rate accuracy with V-V's newest, N570, if you'd like to give that a try. As far as the bullet weights go, yes the heavier weights will be a bit harder on the barrel than will a lighter one. They'll also usually give you better performance at distance, and that's what you built it for, right? Load it up for performance, and just accept the fact that barrels are temporary pieces that need to be replaced from time to time.

    Thanks everyone. This will give me a starting point and I will have a good supply stocked before the rifle makes it home. Are there any other tools for success to create the best hand loads for the 338LM?
