Using magnum primers in non-magnum loads
The title says most of it.
A buddy is trying to get back in reloading after a ten year hiatus, and tried to buy some primers in the midst of all the current craziness.
All he could find in Large Pistol primers were Magnums.
He wants to use these primers primarily for .45 ACP reloads, especially with Bullseye or W231.
Soooo, how much of a problem does this actually create? I recall reading that magnum primers have a longer/hotter burn to ignite larger powder charges.
Should he adjust his loads because of these primers, or is case density still important (especially with the issue of 'detonation', which may or may not exist).
What says the group?
