Barrel Lenght

[Czy_Horse]

Suns out for a change, though I'd compare different barrels length velocities.
Both rifles using mixed 357mag brass, 17.0gr Lil'Gun & 158gr Campro TCFCP

8 rounds - 18.5" - Marlin 1894c 357Mag/38Spl
1907fps high, 1823fps low, 1867fps avg, 84 es, 26 sd. GRTs estimate, 1835fps

10 rounds - 24" SS Rossi R92 357Mag/38Spl
1993fps high, 1907fps low, 1953fps avg, 86 es, 24 sd. GRTs estimate, 1918fps

The Rossi's about 85fps faster with the 5 1/2" longer barrel. GRT estimated an 83fps difference.

Primers? I'm trying to produce a similar load.

2.5 pounds of energy difference I'll take the shorter one.
