It's a good round if you can find factory ammo for it or if you like to reload. Also finding cases could be a problem. It is based on the Rigby case. There are other more common rounds out there that will do just as good and the components to reload them are easier to find.
Its a great round perhaps a bit better than the 338rum or 338-378. 250gr bullets are usually the top end weight for the twist rate in most factory rifles. Reloading is a must if you want to shoot a lot and don't want to really rack up the $$$. Norma and Lapua make brass. Don't even bother with bullets like a partition, stick to designs more like the accubond.
Hornday probably makes the cheapest factory ammo, with the exception of HSM, but both are kind of hard to get right now due to the increase in the popularity of the cartridge.
Let me start off by saying that I am a scaredy cat.
For someone that spent 3 years in 82nd Airborne jumping out of all manner of military aircraft, my friends find this ludicrous - but... it is what it is!
Climbing stand? Yep, still scared - put me up 15' and that is about it.
Ladder stands? I am better in these - but still cautious.
Chain on stands? Used to love them, now they terrify me.
I was once ridiculed for putting chain on stands waaaay too high - some of my friends...
