Long range loads for the 6.5/300 wby

Long range loads for the 6.5/300 wby
« on: April 21, 2018, 04:50:28 AM »
After multiple powders and several bullets, 2 bullet types and loads have provided the best accuracy for long range in my 6.5/300 RC Accumark.
I did rebed the action and use a Nightforce NSX 5x22x optic.
Hornady 143 grn ELD-X
US869- 89grns , C.O.L 3.610
Velocity Av 3250
Berger 140 Hunter Elite
US869-89grns, C.O.L 3.610
Velocity Av 3288
Note: testing was at 3400 Alt
         3 shot cold bore groups provided best results. 4,5 shot repetive groups showed slight signs of heating, resulting in climbing groups.

Those two bullets will carry the  accuracy out to long range. The 143 grain ELD in my 6.5-284 shoots good out to 1000 yards so far

I should note the groups on the white paper with dime are Berger 140 Hunter Elites.
