useless gun??? .38 Special, 2" barrel...and PORTED

[highorder]

thats really interesting.

I wonder if you would do us the favor of measuring the cylinder gap on those two guns. A few thousandths may be enough to produce the velocity increase in the ported gun, especialloy with the optimized short barrel load.

thanks for the efforts!

Barrel-cylinder gap

Highorder...I sure will measure the gap. I will post it here and this link where I am picking up the topic.

Thanks

food for thought:

Cylinder gap is particularly critical on short-barreled and/or marginal caliber guns. If you need every possible ounce of energy, a tight gap helps. Some factory gaps will run as high as .006"; Taurus considers .007" "still in spec" (sigh). You'll be hard-pressed to find any new pieces under .004" - probably because the makers realize some people don't clean 'em often (or very well) and might complain about the cylinder binding up if they sell 'em at .002".

Wow!

I am sure someone on here will have a whiz-bang explanation as to how the ported parrel produced higher velocities.

Thanks for the update Southern Shooter!

some guns have "faster" barrels than others. its that simple.
