300 WEA MAG 208 GR AMAX LOAD DATA NEEDED

[CADDIE5]

I was invited to shoot with f class buddies at a range to 1680 yds for fun at steel buffalo (1280 and 1680). 300 Weatherby Mag Accumark rifle is only rifle that I have that will reach 1680. Illinois elevation 600 ft. I shoot f class to 1000yds with Barnard 308 win rifle. Buddy built 300 PRC rifle for 240gr bergers and A tips to have fun at 1680. I have no intention to build a dedicated rifle.
I have 208 gr amax bullets (500), 200 gr Berger hybrids (48), and Berger 175 vlds (100).
300 wea mag Accumark Rifle chamber info :
208 gr amax 4.0285" base to lands coal
3.7385" bullet seated at shoulder junction
200 gr hybrid 4.06" base to lands coal

None of those powders. Need slow powders. H1000 , retumbo, us869, 8133, also your barrel will probably not perform up to what you want because it's mostly a hunting barrel, if my guess is right. They get hot really quick. You will need an elevated base i think, scope doesn't have enough elevation adjustment. Hogdgon load data won't have the exact bullet's you are using but i always do extrapolation with close bullet's.

Scope base is 20moa picatinny rail. Scope rings are Burris XTR Signature rings so can do 40 Moa with rings. Scope is a Sightron S Tac 2.5x17.5x56mm so it has 80moa elevation. I don't believe elevation will be an issue. Nosler had 210 gr Accubond LR showing IMR4350 as most accurate powder tested. 72gr max @ 2920fps; 70gr @ 2833fps. Sierra accuracy load for 210 gr hpbt was with US869 @ 97.9 gr @ 2900fps. Berger manual has 210vld showing IMR4350 and H4831SC. We are shooting 5-6 rounds then next guy is up so barrels don't heat up since they are not target wt barrels.
Any recommended jump?
Any one able to email me pic or pdf of Hornady Reloading Manual page for 300 Weatherby 208 AMAX. Don't know any place selling US869 locally. Cabelas might have H1000 or Retumbo.
Thank you for all replies.

Jump is something i don't fret over, i just load as far out as reasonable without jam. Powder type is the magic for accuracy. Different guns like different powders. Us869 is very good in my 338 Lapua. I only looked at my hogdgon load data. I always have good accuracy with the slowest powders/ full case.
