As far as loads go. What kind of rifle are you using?
The Husky I had was a 98 Mauser, and the chamber was REALLY long.
I seated the bullets as long as I could which ended up being near the same COL as the 9,3x62 is listed at in the Speer manual and the 270gr bullet.
For powder I tried H4895, H414, IMR 3031 and the best was H335.
The rifle wasn't picky as far as grouping, it shot all the loads well.
I worked up the 270gr Speer to 2460 with H335 and had no issues except for where the iron sights were regulated for a fat 286gr going much slower. Expect to hit much higher if you are using the irons.
It would group 1 1/4" , 100 yards, shooting off one knee which seemed to work for me.
