Re: Load Info Requested!
Heres goes an excerpt I took from a very nice article wrote by Terje Fjørtoft ( Norway ) on both the TRG-22 and 42 rifles. Hope it helps.
Reloading for the TRG-42 (.338 LM)
For the .338 LM, I started with a 250gr Scenar and 95 grains of Vitavuori N-170. That load was very accurate at about 850 m/sec, but it produced excessive muzzle flash. And, in the winter, the muzzle velocity was inconsistent, and there was too much unburned powder.
Next I tried Norma N-15. An 84.8 grain load of N-15 proved very accurate at about 880 m/sec. With that load I shot my best TRG-42 group at 380 meters. I set the 250gr Scenar to touch the rifling with 93.2 mm COAL, and I used Federal 215m primers in Lapua-brand brass. Norma MPR2 (92.6 grains) and VV N-560 (85 grains; 860 m/sec) also were very accurate with the 250 Scenar.
My seal hunting bullet was the 200gr Nosler BT. This bullet grouped very well with 90-94 grains Norma N-15. Velocity was about 970m/sec if I remember correctly.
I also tried the 300 Sierra MK, and got 1/2" 3-shot groups at 100 meters with 93.5 grains of VV N-170, but this combination produced terrible groups at longer range.
Loading for the .338 LM was not difficult--about the same as loading for .308 Win, except that you use nearly twice the amount of powder. I didn't crimp the bullets in the neck, didn't use any special tricks or neck lube. I used RCBS .338 LM full-length die. That functioned, but it would not be my first choice today. Overall, my better loads in the .338 shot in the 0.5-0.7 MOA range. My best group was four shots in 25mm (1") at 380 meters (416 yards)"
