It might be rare in the USA but that combo is very common in europe. If your reloading stick with a 286 grain projectile. The Woodleigh RNSP works well.

RWS and Norma make great factory ammo.

It is not a magnum and earnt its reputation in Africa in the first half of the 20th century clearing vast tracks of future farming land (of plains game) with conventional cup and core projectiles. I had very little success with anything heavier opening up at impact velocities.

I was able to take game in Africa out to 260 paces but that is NOT what this cartridge is designed to do.

You will love it in that Sako.
