I would by all means take a spotting scope along.
Spend as much time as possible sitting behind the shooters and watching the vapor trail of the bullets.
You will learn much as a result of doing that. Best to keep the power at a lower setting so the image is clearer.
You will soon learn which the better cartridges are simply by watching.

Until recently, 100 yards/meters was the farthest I'd shot.

I did another class recently with a maximum distance of 600 yards, and had 1st round hits on all 7 plates out to 600 yards with 168gr GMM. I believe the steel ranged from 12 x 12" at 350 to 24 x 24" at 600. Had my best hits at 600 after some tweaking along the way.

Made some minor adjustments from the ballistic chart I was using, but it all fell into place pretty well. Wind was mostly light.

Very enjoyable day, and I learned a lot, but it also showed me I've got a lot to learn...
