Using non-magnum primers with H110/W296 is asking for trouble. Sure you might do it your whole life and never have an issue, but it's not the correct method. H110/W296 should never be downloaded more than 3% and should always be touched off by magnum primers.

2400 is easily ignited by a standard primer and requires no additional help to burn. In fact Alliant specifically recommends standard primers with this powder. H110/W296 is slower, more finicky about ignition, and requires the extra flash from a magnum primer to burn reliably.

WLP primers for standard and magnum loads are a bit of an anomaly. Winchester primers are generally hotter in all variations, and testing probably made the manufacturer confident enough to promote them for standard and magnum use. Personally I use Federal magnum match primers for my big bore handgun loads.
