Been shooting 215 gr. SWC Lead JK Bullets in the 41 mag for awhile now. I have a 500 ct box of Oregon Trails 215 gr. SWC bullets lying around and decided to open them and take a look. First thing I noticed was the lube was a different color. The area above and below the lube groove had slightly more surface on the Oregon Trails bullets. I weighed 10 each and got 210.2 gr. for the Oregon Trails and 212.2 gr. for the JK bullets. Both bullets High/Low was around .4 gr. The length was the same for both. Diameter was also the same. Looked at the box of Oregon Trails and read where they claim rated #1 in accuracy. And the test was born. After having a bunch of the JK Bullets already loaded with a big batch of new Starline brass, the only thing left was load some Oregon Trails bullets. All were loaded with 7.1 grs of W231 powder, Light/Medium crimp and Win WLP primer. There will be 5 volunteer 41 mag pistols for the bullet test. Two will be Ruger Blackhawks with 6.5 barrel length, Two S&W Model 57 in 6 and 8 3/8 barrel and a Ruger Super Blackhawk Hunter with 7.5 barrel. They all got 6 rounds of each bullet through them @ 25 yds shooting with a front rest. Here are the results.
