Ran some of the "RUGER ONLY" cast Penta HP's out of my 1894 Marlin in 45 Colt this Monday.
Average velocity was 1546fps.
Load was 24.0gr of 296, virgin Starline case and a CCI 350 primer.
Today I went to the range again but this time with my son.
The above load was shot into wet catalog books at a measured 25 yards.
Recovered weights went from a low of 103gr to a high of 112gr.
My average weight for this boolit was 313gr.
Average recovery depth was 9" of the wet catalogs.
Here are pictures of the results.
