Dear friend, I am a 338 LM long range hunter and shooter. I own an HS HTR, and worked a bit with a Sako TRG 42 of a friend, too.
Let me suggest you to try, with 250 grs bullet as Scenar, loads between 82 and 88 grs of With. N 560.
On my HS they work great (HS groups best with 86, but still manages 88; Sako prefers 82-84).
You will also experience a strange "smoothness" in recoil, making it very pleasant to shoot. The only bad thing is quite a lot of muzzle flash, but here we do not have problems of countersniping.
Accubond 250 on the market ???? I am looking desperately for a 250 hunting bullet comparable to Schenars anf Lock Bases..... Tell me any news !
Added a cheek piece last week and got to the range again today testing 92.5 to 94 gr RL25 and the 250 Scenars. I did all my shooting a 200m. It looks like the load settles down around 2830-2850 fps and it looks like I will be working within a range of 93.0 gr RL 25 to find my pet load. I did notice the groups opening up after about 20 rounds - curious if the fouling is the issue, or just me losing focus near the end of my session? Note: Average velocity with the 94 grains RL25 was 2937 fps, but the groups opened up and recoil was stiff.
