A Few 338 Lapua Magnum Loads with the 285 gr Hornady BTHP Match

[Andy]

Savage 110 FCP HS - 26" barrel

Shot at 5 degrees C

Lapua Brass
Federal Magnum Match Primers
Hornady 285 gr BTHP Match
3.700" OAL, 0.030" off the lands

Listed in rough order of Burn rate in this combination:

RL25 - 90.0 grs - 2750 fps
H1000 - 93.0 grs - 2750 fps
Retumbo - 95.0 grs - 2825 fps
RL33 - 100.0 grs - 2750 fps
H50BMG - 102.0 grs (compressed) - 2600 fps
US869 - 108.0 grs - 2875 fps
20N29 - 100.0 grs (compressed) - 2650 fps

I consider the RL25, H1000 and Retumbo as max loads for this combination. I knew that I'd run out of space for H50BMG and 20N29 and would too for RL50.

I was surprised to find RL33 to be as slow as it is - it seems to be at about where the old H870 was and hard against RL50. I could probably go up another 2-3 grains.

I consider US869 to be a Max Load, but could fit another two (2) grs.

I have not yet tested any load for accuracy.

Lapua has load data for that bullet with Viht powders and it was used for reference with these powders: http://www.vihtavuori.com/en/reloading-data/rifle-reloading/-338-lapua-magnum.html

I am just using the search feature on the site to try and scrape up info just like this. I just picked up a 110 fcp and am gathering info as I gather components. This is a fairly pricey caliber so I am hoping others might jump in and let us know what worked well for them.
