I would use a chronograph for your load development while watching for signs of high pressure. Assuming you are using a lever gun so be aware of sticky extraction. Start low and work up.
I was just reading up on the 360 BH yesterday. It actually out performs the 35 Remington. This is due to...
Which M48 did you find?
My wife has a M48 Mountain Carbon in 30 Nosler and a buddy has one in 33 Nosler. They have a carbon wrapped barrel and weigh in at 6.0 lbs. Excellent shooting rifles.
Were you able to get ahold of Nosler for timing on a M21 in 33 Nosler?

Fotis,
Excellent load development and shooting. And that big bullet should make two holes in an elk giving you a decent blood trail with that speed and energy. A big stick in a small package.
