Coll416,
I got a mate to run to check on your load, to get 2600fps in a 9.3x62 if using Alliant R17 & 286gn Woodleighs you would be WAY over the recommended maximum of 56K psi - something like 72K psi!
It also proposes about 106% which would be a very compressed load as well.
I'm not say it doesn't work in your rifle - but to me that's just too hot mate!
Never had the chance to use Woodies on anything yet, the 270gn Speers are accurate, good on pigs at lower velocities about 2200fps - drills through them!

Myself been reloading since very early 80's, a slow & steady process in learning & a very long way to go yet for me before I'm starting to get half decent!
Watch your brass mate, check for case separations after every shot.
Stay safe!
