Just bringing back this thread. Melvin Forbes died this week. He created the Ultra Light Arms 5-pound rifle decades ago, and the .284 Winchester was his most popular cartridge in his Model 20. I bought a NULA Model 20 last year in .284, and I'm going to use it for elk and deer this fall. Yesterday I got what I thought were pretty good groups (3/4 inch) at 100 yards with this super lightweight rifle. I'm still in the early stages of load development, but using 150-grain Nosler Ballistic Tips (I plan to switch to Accubonds for hunting) I got 2972 fps average with 53.0 grain of RL-17, and 2948 fps with 58.0 grains of VV N-160. Increasing RL-17 to 54 grains got me 3024 fps average, but the group opened up. This is a 22-inch barrel. I need to work around those charge levels to see what works best, but these are very useable for mountain hunting and shots to 450 (my personal max).
