[QUOTE="Dean2, post: 1577563, member: 26077"] What you are expressing is opinion, not fact. Magnum primers are not a stick of Dynamite, they are simply a more robust primer. Using a magnum primer is no more likely to cause high pressure issues than a hotter batch of the same powder. The primer is just one component in the loading/pressure equation. A smaller capacity case, military vs commercial brass, can and does cause a larger change in pressure. If you test your loads in +80 weather and again in -20 as I do, you will most certainly have a safe load. If the load produces safe pressure and velocity, small SD and ES at +80 it is not going to be over pressure at -20. You are free to do as you like but spreading irrational fear is not helpful. This was written by Allan Jones who works for CCI/Speer. He develops and tests their primers: The whole article can be found here [URL]http://www.shootingtimes.com/editorial/ammunition_st_mamotaip_200909/100079[/URL] Also, if you call the help line and talk to the Hodgdon loading department they will tell you essentially the same thing.
