[QUOTE="flashhole, post: 832160, member: 21375"] The difference in primers will show up most noticible with small powder capacity cartridges like the 22 Hornet or 221 Fireball. I have been experimenting/loading for my 25-06 since 1998 when I bought it new. The -06 case is a large powder capacity case for the small bore (25 cal) and your primary concern should be getting good ignition of the large powder column from your primer, especially in cold temperatures. The most influential variable in the equation is the powder itself, not the primer. H4831SC is in the Extreme family of powders and is very insensitive to temperature variations (good choice). Primers can vary significantly in brisciance (hottness) when full scale comparisons are made (small, large and magnum primers) but large rifle primers are not too different one manufacturer to the other. I ended up migrating to magnum primers for the 25-06 and use the same primer for my 7mm Rem Mag as I do the 25-06. Use what you have on hand. [/QUOTE]
