[QUOTE="Dean2, post: 1576728, member: 26077"] I use magnum primers in ALL hunting loads to ensure good ignition in -40 weather. I develop and test loads in the summer using a Chronograph, then retest them at -20. I have had CCI mag primers fail to ignite, (you open the case and the partially ignited powder is all clumped up in the case so you know the primer went off) or click booms in large capacity cases like the 7 RUM. Anything that uses 65 grains or more gets Fed 215 or Win Mag primers, those under get CCI Mag primers. For target loads shot in the summer I will use regular primers but not for hunting loads. A hotter burning primer has both increase flame heat and a longer duration of burn and will usually give you more velocity and higher pressure but it does not change the burn rate of the powder. I do not believe the comment about it causing powder to fully burn in the case while a regular primer has the powder burn further down the barrel. That is controlled by the powder burn rate, not the brisience, or duration of the primer. If you vary any component in a published load, primer, bullet, case make or gun used you need to start low and work up. Since you will never be shooting the same batch that was actually tested it means all published loads are GUIDELINES. To use them safely you need to use the velocity, SD, and ES to judge your own loads and gun. By the time primers flatten, pockets expand, ejector marks show up or heads expand you are already WAY past recommended pressures. So long story short, yes you can use the 215s just be careful as always when working up the load. [/QUOTE]
