Max load for 6.5-284

[moosehunter]

I did a ladder test last year with this caliber. Lapua brass, Sierra 142gr. MK, H4831sc, Fed 210M, 29" 8 1/2 Gaillard barrel. .3gr. increments 52.6gr. showed no pressure with easy bolt lift and primers not flattening. 52.9 blanked the primer. It was looking like I was just coming into a nice sweet spot. I settled on 50.8gr. where the first sweet spot showed 2912fps. Id like to get between 2950 and 3000fps where this bullet is supposed to shine. Did I hit a bum primer or what is the max. load for this puppy. I know what Hodgden lists and I also know they are VERY consertive with they're listings.
