I have been reloading .308 for a while and am now getting ready to load for a new .338 Lapua I just bought. I want to have the furthest effective range (supersonic) I can get.

I have a 25.5 inch barrel on a Lawton action.

What powders work well in this cartridge and what is the best bullet available for ELR?

Thanks
 
Re: .338 Lapua

The sierra manual says to use Viht N165 for 250 SMKs and for the 300's use IMR 4350.

Anyone have experience with these?
 
Re: .338 Lapua

Thanks. I had already read that thread. A lot of guys are using powders that I can't find right now. I was trying to find some other options for powder.

I did find some RE 25 in 1 lb containers. I can't find primers to save my life, but of course no one can right now.
 
Re: .338 Lapua

I found some RL25 and ordered it.
This morning I found some 4832sc.

Which is going to be the better powder for the .338?
Is one less temp sensitive than the other?
