123 Nosler CC load data question

I wouldn’t use the Alexander Arms data for Accurate 2520 as it is several years old. The current Western/Ramshot/Accurate data list 29.6 grain maximum with 123 grain SMK and 29.5 grains of A-2520 with Lapua Scenar.
Accurate powder has been manufactured in different locations over the years and I trust Western’s online data. If you have a chronograph and are careful you can work up but you might shorten the life of your bolt. A few years ago a Friend shot a lot of A-2520 in 6.5 Grendel and he backed off from the AA listed maximum charge as he thought it was to hot.
The online Nosler data I have list maximum charge 28.5 grains of A-2520 with 123 grain CC COAL 2.250 with Rem. 7 1/2 primer and 125 grain Partition COAL 2.240.Last edited by VASCAR2; 03-17-2019, 07:38 PM.
