Wow!

Oh yeah, I agree with all you said. The 15 minute rule is a lot ...stupid. I've never liked fleabay much for the same reasons but some things you just don't find around this area. The only purchases I've made on any gun auction sites were buy it now type auctions with realistic shipping fees and no add ons for credit cards.

Btw, the Ruger you have is a good example of a pistol I've never seen and probably never will in this area. Was it a 'convertible' BH with a cylinder in 38/40 and 10mm? As I said, not familiar with it but find it interesting. I like Rugers as they're usually a good value for what they cost. Plus the BHs are strongly constructed......Ruger only loads, etc.

I've bought quite a bit of C&R type guns at Gunbroker. Where else you going to find a Winchester 95 originally chambered in 7.62X54R. And the going rate for them is about 2-3 GRAND! I paid less than half that. (Plus it goes with my 12 Mosin Nagant rifles!) I've bought a Walther P-1 there, a couple Yugo Mausers. The only time I got burned was I put in a joke bid of $40 for a Hi-Point .45. Imagine my shock when that bid WON! It cost me more to ship and and pay the fee to my transfer guy.

Worst POS I ever bought in my LIFE!

As long as someone is willing to pay the price then I guess it's worth it.

Removing the gap entirely (for testing purposes, with no detectable gas leakage) showed no difference or appreciable loss of velocity, and well within the MOE of any chrono.  I've done this with most of my revolvers, and the results are always the same.

I mean I just find that hard to believe. I am NOT calling you a liar, but there almost HAS to be some kind of velocity loss. I mean there can't be a flash there if no gases are escaping.

This was also documented in a Handloader article in the last few years.  They built up a 1917 S&W to have the same length from the head of the case to the muzzle of the barrel as a 1911.

Depending on the load they two guns traded velocity back and forth.

They then played with the cylinder gap, and with a big enough gap, the revolver started to lose, but it was a far out of spec gap.

End result is that it doesn't take much gas to feel or see at these temps or pressures.  And even though we perceive a bunch of gas leaking there, relative to how much gas there is, what we see isn't that much.

And, 90% of the velocity comes in the first 1" of travel.

Between those two factors, a revolver with a proper cylinder gap is at no disadvantage.

I know it sounds counterintuitive, but the fact is, the variables were of the least affect, and not detectable within any margin of error.  Temperature and humidity have a much greater (detectable) affect than the gas leakage on a properly gapped cylinder.

I need to quit beating this dead horse, but how can a 6" revolver NOT have less velocity than a 6" semi? I mean you SEE the flash. You KNOW gas is escaping.

.1% of the gas escaping will have less impact than a .5% variation in charge ( that is .05 grains in a 10 grain charge) or even a .0001" variation in groove depth.

No one is saying it makes no difference in the theoretical sense.  We are saying that the difference it makes is so tiny as to be completely obscured by other factors.

Personally experienced scientific laboratory fact trumps rumor, every time.

Well, I think I stated elsewhere that velocity really doesn't matter to me anywhere near accuracy of the load. And my Dan Wesson Razorback LOVES my reloads!

Aw well, since both my 10mm's are 1911's, I' stick wit what I got.
