Re: 260 rem
I use the standard primers for sighters, foulers, hunting ammo, Garand ammo, and for load development.
<span style="font-style: italic">(edited to add: I use H-4350, CCI-200 or BR-2, 120/140 Nosler BT/SRA SMK/HDY 140 A-Max, as well as 142SMK. My hunting loads use 120/140 Nos BT/Partition and/or HDY 129/140 SST. My typical charge runs from 43.8-45.0 gr (the latter for the 120s). Varmint loads use HDY 95 V-Max and 47gr of H4350.)</span>
The match primers only go into bolt gun ammo intended specifically when firing for score.
While cost is a factor for me, it's more about what's appropriate to the task. I won't waste a match primer on tasks of secondary importance, and I won't invest my time crafting match ammo, and then stick a non-match primer into it as long as I have the option.
I work under the asssumptions that the performance is adequately similar, and the costs are not. Exact equivalence has no meaning in a system that is dependent upon human performance. We're not machines, and maybe that's the main point.
