Spey, using pistol primers in any rifle cartridge CAN be a bit risky. Fortunately the Hornet is not very high pressure round as rifles go and I can understand this practice working. But it's worth mentioning that it's not without risk of some fairly serious gas blow back from primer rupture. I learned this lesson pretty well during the years I had a Marlin .357 rifle. For my hottest .357 Magnum loads, I simply had to use small rifle primers as the pistol primers couldn't stand the pressure and would rupture. I don't dispute your idea at all but I do make mention of this for some of the less experienced reloaders. Ruptured primers can be hazardous to a shooters eyes.
Good Point, safety always first.
Hogdon's 'Lil Gun was designed for small guage shotgun shells like .410 and 28 guage, maybe that's why it worked without any pressure problems. 13gr is almost a compressed load in the 22 hornet and over 300 rounds with this load produced no pressure signs at all.
