Pedersoli PA Rifle 32 cal

[Sim Carstairs]

I’m looking for data on the Pedersoli Pennsylvania rifle (percussion) in .32 caliber in regards to accuracy and loads. Thanks in advance.

Pedersoli is a top quality brand.

I've shot .32 rifles with a patched lead round ball and 25 to 30 grains of 3F.

My Pedersoli .32 Pennsylvania shoots two loads very accurately. My early season squirrel load is 15 gr of 3f with a .311 ball and a .015 patch lubed with mink oil. Close to quarter sized groups at 25 yards. Later in the season, when the leaves have started to fall, I switch to 25 grains of 3f with the same ball and lubed patch. I get 1.5" groups at 50 yards with this load. That is about as far as I will shoot at a squirrel with iron sights and my ageing eyes.

The Pedersoli manual recommends powder charges between 31 - 40 grains, a .315 ball and a .010 patch. --->>> https://www.davide-pedersoli.com/uploads/supporto/9TABELLA DOSI POLVERE 2014_06.pdf

The .32 has ballistics similar to a .22 magnum.
