Showing promise .338 LM

Even at 300, wind can play a factor (as attested to at the last competition at Mission that I was able to watch a friend compete in for the first time). At 600, wind can play a major factor, so it is wise to stay in the 1-300 range (it's the lesser of two evils, 338LM bullets might take more distance to fully stabilize, BUT wind is wind and the greater evil ;) ) Hope your loading to ogive and testing by varying bullet seating depth? It's the best way to find most accurate load, with minimal shots. Once you know how well it groups, move on to far greater ranges :) Even if a rifle shoots 1/4 or 1/2 MOA at 100-300, it won't at 1000 due to wind ;) unless you're an amazing wind reader... [OK there are other factors too - temp, pressure, coriolis effect...and most importantly...shooter skill]

You should be load developing in zero wind .... Not my first day at 1000 yards
 
I've been using Hornady factory loads and reloading the brass for a few years now and have had no problems using it in my Rem 700P and now in my Desert Tactical SRS. My buddy has a Timberwolf and it sticks in his chamber as well which worked out great for me because he gave me his brass :)

I have a couple loads now that are doing 1/2 moa but I know the DTA is capable of more so I'm still working on my load.

Here is the best group I've done so far. Hornady factory 250gr first day our with the new rifle. It should say yards not meters on the target though.
