Went shooting today and this is what my chrony had to say.

30-06 24" barrel Interarms mark X

150 Sierra spitzer, rem cases, federal 210 match primer. 3.225 oal

H4350
56-2886
57-3023
58-3088
59-3121
60-3191
61-3240, 3250
62-3269, 3278

Looking at my cases they measured fine but the 61 and 62 looked like they had shiny marks on the bottom of the cases. Primers all looked the same for all of them.

I am gonna go with 59 grains with this one.

These are my loads with my rifle so work up.
