I've owned a few over the years, never could get them to break even 1.5" at best. I recently picked up at a good price an older, Belgian made in 300 Winchester. Started playing with loads using my"go to loads" of 180 Partitions , 75.5gr of RL-22 or 76 H831, both with Fed 210 Match primers and WW brass, but I had some Remington brass so on a whim, i tried them and this is what I got (RL-22 lower group)
So then, I saw Norma had their ammo on sale for 24 bucks/box, so what the hell and this is how they did:
Now I don't know how they'll hold up at 300 mag velocities on elk, but I think I got myself a good elk "timber rifle", but either way, I was pleasantly surprised.
