And the subject is the slide's velocity and momentum...not the momentum transferred to the frame and the hand via the springs. And both of you...
There are a few problems with that approach...not the least of which is variations in ammunition from lot to lot or even within the same lot....
Momentum will be conserved unless an outside force...and you know the rest. You're still trying to ignore the outside forces that the slide...
Probably for the same reasons that the original spring was 14.5 pounds...nominally. To make sure that the slide will return to battery even when...
The availability of varied spring ratings makes that both convenient and possible...but back in the dead days before they were readily available,...
Yes. That's why I said that it's a hypothetical...and that we're assuming that acceleration is linear. And I mentioned that a fast powder would...
Let's do a hypothetical to illustrate the difference between muzzle velocity and rate of acceleration. I love hypotheticals because the only...
I'm not arguing or denying the principles of the conservation of mementum...but momentum has to be established before it can be conserved...and if...
Only in the absence of outside force or in the presence of equal outside force...and there are outside forces that are acting on the slide the...
If you're determining the slide's maximum velocity, then all that applies. But the slide's velocity /energy/momentum at the terminal point of its...
It's way too complicated because it operates on the assumption that the spring is there to save the frame. It's not. It's there to return the...
The chart isn't all wrong. It's just a little too complicated. There's no sense in trying to precisely match a spring rate to the...
There's more to the ejection distance than slide speed in recoil. I set up a friend's Springfield exactly like my range beaters. 14-pound recoil...
Just so. A point of interest is that...in the patents...Browning referred to it as the "re-action" spring and not the recoil spring. Since it's...
In spite of that little hijack attempt... Recoil...which is what the slide does...is nothing more than backward acceleration, and its velocity is...
I beg to differ, sir. I strive to stick to the facts. Apparently you didn't read the part where we discussed that "about" 90% of the bullet's...
And you're correct. Force forward is force backward. If there are X units of force accelerating the bullet, there are X units of force...
Back in 2007, gunsmith and custom knife maker Wild Bill Caldwell was our houseguest for 2 weeks while he attended an engraving class at Montgomery...
Let's do a little simple math. The combined mass of the barrel and slide in a 5-inch gun is roughly 32 times that of a 230-grain bullet..which...
Write a book. If only I had the time. I barely have time to make short posts on a couple of the gun boards. It's not about being correct in...
