7mm PRC Barrel Length vs Velocity

[JRittel]

Recently completed a barrel chop down test with my 7PRC (26" down to 16"). I used the same barrel that was used for compiling the data in my cartridge guide, so hopefully reasonable extrapolation can work.

I have this cut down test in both blog form and as a youtube video if you want to see the all the details, but here is the meat and potatoes of it!

195 EOL w/ Retumbo
175 ELDX Factory ammo
175 Elite Hunter w/ H1000
165 TGK w/ H4831SC

Thanks for the data JR
My 7 PRC is a 20". Similar velocity as per your graph. 2890 fps 20 feet from the suppressor. !80 gr VLD over WC860. Not sure if I'm SAMI but no pressure signs.

That 180VLD performs VERY well in every 7 PRC barrel/rifle I have played with. With the 180ELDM, 180 Hybrid and the Elite Hunter bullets on either side of it I feel like it unfairly gets overlooked.
