Super Redhawk .454 Cylinder Throat Diameters
« on: June 11, 2011, 11:10:52 AM »
Does anyone have first-hand knowledge on throat diameters in the .454 SRH? I know Ruger typically produces them undersize in the .45 Colt Blackhawks. However, I wonder if they pay more attention to detail when they cut the .454 throats in the SRH.

I've only measured the throats on one Super Redhawk, but they measured  .451". My 4" Redhawk measured .448". Hope this helps.

I think this guy measured the cylinder he used in the conversion?

Throats that are smaller than nominal groove diameter need to be opened up or accuracy will suffer and the gun will lead. Throats that are too large have similar problems.
