I read the 243 thread that was just started about powders and didn't want to hijack. I know alot of people recommend using magnum primers in rounds with ball powder that have larger capacities.
My question is, does the 243's average load out of a nice medium to slow Ball powder (like 40-48 grains) REQUIRE mag primers for consistant ignition and acceptable ES/SD numbers?
