According to Quickload. 90 to 92 gr of ADI-2225 is MAX charge weight for the 285gr Hornady projectiles.

in a Sako TRG42 we loaded up to 94 grs Retumbo with the 300 gr Scenar but the ES was too high for consistent hits at long range,,we got best results in varying conditions at 91.5 grs ,,,that was before RL33 and no more than we shoot it have stuck with the 300 Scenars and 91.5 Retumbo as the load for that rifle,,

if we shot it more and had somewhere to shoot a mile or more I would try to get the 300 Bergers to shoot at mag length and see if RL33 will shoot as fast and accurate as people claim,,

1,500 yards and closer I like the 250 SMK and H1000 very well,
