Home Forums Reloading Handgun Reloading Winchester Large Pistol Primer Questions

I've been reloading for well over 50 yrs and somehow have never used Winchester Large Pistol primers. Always used Remington, CCI, or Federal and occasionally one of the foreign brands. Picked up a couple bricks of WLP primers recently and noticed for the first time that on the box is printed "LARGE PISTOL FOR STANDARD OR MAGNUM PISTOL LOADS".

Questions are: do these WLP primers really work as well as dedicated standard or dedicated magnum primers? Are they really a universal type of LPP? And especially do they work as well as a dedicated LP Magnum primer in cases where the load data specifies a Magnum primer?

Thanks in advance!
