VV 550 or 560 loads for 284?

[ericskennard]

I am looking for load data for .284. I am using Lapua 180 grain bullets and I would like to try N550 or N560 powder. Does anyone have any load data for them in the .284?

Hi Eric I’ve been using Vihtavuori N160 for years in a .284 and 180 scenar bullets.
I use 54g of powder, if you are going to try this please reduce load by 10%.
Great Barrel life and is very accurate in the 2820fps nod.

I’ve had some great results

The load data you are showing is for the 7mm Remington Magnum. I would never try those loads in a 284.

N160, BR-2, 184 Berger 0.015" off lands, 0.0015" neck tension with a 0.0145" neck wall, straight .284, once fired Norma brass, 52.0gr yields 2825-30fps. Same load with 0.0005" neck tension, new cases, 52.6gr yields 2800fps. I would expect the N5XX series to also be sensitive to neck tension so keep that in consideration with starting loads.
