Help with 338 Lapua Loads

Gents,

I will be shooting this cartridge in the near future.

Would appreciate any info that you have on loads.

Will most likely start out with the 300SMK.

Thanks in advance.

    xring01,
    I started shooting the 338 Lapua about 4 months ago and with some advice from Chris Matthews found that 93grs of Retumbo works pretty good in my rifle with the 300 SMK, he said his likes 94grs. As always work up slowly in your rifle.
    Take care,
    Wayne

    I shoot the SMK300's with a PGW timberwolf.
    I have tried Retumbo 92-93 grains. The pressure signs are less, but you can't beat the accuracy of 92 grains of H1000.
    I get 2780-2790 fps out of it, and groups as good as 1/5 MOA at 200 yrds. Of course it works well at 1000 yrds also. This was seated against the rifling. Hope this helps.

    What dies and shellholders are you using?

    I use Forster/Bonanza Benchrest dies and a RCBS #14 shellholder. For the money I think the dies are pretty good, especially the seater die.

    I have a Remington 700P in 338LM. For some reason H4831 works better with 250 grn SMKs. I've tried Retumbo, H1000, RL25 with about a dozen loads each at different COALs. The faster H4831 is just more accurate in the rifle. I've found the 85.5 to 86.0 grains of H4831 seems to be the magic load giving me .46 MOA average.

    Right now I'm also working up a load for the Hornady 225 SST's with H4350.

    Per the shellholder I have the RCBS#14. It's a little sticky with Lapua brass - get the redding (i think it's #35). I'm switching as soon as it arrives.

    I have a McWhorter Custom .338 LM. I'm using Federal 215 primers, 92.0 gns. of N560 powder, shooting 225 grain accubonds 3300+fps. I get 2.5" groups at 800 yds consistently. Hope this helps. What kind of action are you running? I have a Stiller Predator which is very beefy. This is a pretty hot load, so make sure that your action is capable of handling such loads... Good Luck!
