I'm reading M. L. McPherson's Varmint Hunter article, Working With The .22 Hornet.

He has some good stuff to say, even mentions K Hornet advantages, 300-MP and Lil gun powders. He likes Fed 100 pistol primers, has a heading titled, "Never Use Magnum Rifle Primers in the Hornet". He talks about piercing and "blanking", primer material extruding into the firing pin hole.

Well, I have CCI 450's and will definitely use them with 300-MP and Lil gun in these K Hornets.

I wonder if Mic was one of the early proponents of pistol primers in the Hornet, or just grafted his thinking onto existing trends.

Maybe I can duplicate gunner's loads without a drop tube, coercing enough powder into a small case to make the 45 TSX work...

From what I see published, the K Hornet case has around 16 gr. H2O, the Hornet, 14 gr. That's a 14% increase in case capacity if I figured it right, (2 divided by 14).
