For the small primers I just milled out the primer pocket.That thought had never crossed my mind as large pistol and large rifle primers are nominally different dimensions. A quick search found this:
Primer dimensions and tolerances
Primer Type Height Min Height Max Diameter Min Diameter Max Small Rifle/Pistol 0.1150 0.1260 0.1745 0.1765 Large Rifle 0.1230 0.1360 0.2105 0.2130 Large Pistol 0.1150 0.1260 0.2100 0.2120
You've not encountered any issues with seating large rifle primers in small pistol primer pockets?
What is the advantage(s) of doing so?
I understand the numbers, but most manufacturers only make tools for large and small primers, Sinclair maybe the only manufacturer that actually makes a large rifle tool.
So, I just used the large rifle in the 44 special and 357 magnum to test.
The 357 magnum look uglier than they are because the pocket does not have a radius like if it were manufactured that.
The number on the 357 magnum were; Average 1212 fps, ES 87 fps, SD 18
