I'm a .284 fan for sure. I've owned 3 RM's over the years. The HMR has performed the best on paper, but is way too heavy for me to carry on long treks while hunting. I have not owned a Tikka to date, but there is a huge fan base for Tikka rifles. The biggest issue I have run into is slower twist barrels on most of the factory rifles. If you want to shoot the longer bullets, this can limit your choices. Decided to change things up a bit and build a 280ai with an 8 twist. I'll be giving up about 100 fps, but using significantly less powder per round. This should help the shoulder on a light rifle.
Good luck. There are many fine rifles out there.
