Looking at old Remington ammunition catalogs, they note use of the 1 1/2 Primer for all Remington 38 Special +P loads. Remington listed the 5 1/2 for their 357 Magnum loads.
I did see on this site someone mention that Remington doesn’t use the 1 1/2 primer in 38 Special +P loads. I’m a bit confused…
Do you see any concern using the 1 1/2 Remington primers in 38 Special +P 158 gr lead/cast loads? My 38 Spl +P loads are within Speer’s reloading manual for 38 Spl +P 158 gr SWC/SWCHP’s.
