I have some magnum pistol primers - small & large - and I'm led to believe that as long as I'm not loading hot loads they will be OK. Any thoughts?

Just do normal load development.

Just like Swamp Donkey said, you should be fine with normal load development.

I've used standard and magnum small rifle primers. I worked the load up and there was no issues.

Sell them to Alpha1, marked up as "reduced power" primers.
It'll be fine what could possibly go wrong?

They will be used in the "pistol calibre" (sorry, Adam) cartridges - .38spl; .357mag: .32/20; .38/40: .44/40: .45Colt.

I like to use magnum primers in BP loads, I use magnum pistol in the 44-40 and 38-40.

I've used up magnum primers up (purchased in the days when mainland UK shooters were allowed to own and use revolvers) in light to medium .38SPL and .44SPL loads, without issue. Very little or no extra energy to the bullet velocity over normal primers that I could tell, even when run over a choronograph to compare.

However, as advised above, do follow normal load development practice by starting 10% below the listed powder charge (from a reputable source), and work up SLOWLY. What might be safe in one firearm might not be in yours...
