you know what *******, I DON"T know everything but I am trying to learn, I am trying to derive the laws that govern firearms by myself so that I can understand the engineering principals behind them. So far I have learned alot, but every post I have made has had some snide or inflammatory...

Nevermind Figured it out, God I love this gun. God bless my dad for trading in his 1911

okay aparently we are idiots and as soon as we got the ruger re assembled the gun would not accept a magazine. We try to seing the pin out and it won't swing all the way out but will accept the magazine, anyone know how to fix this error.

well thanks in great part to your members here I got my first .22 pistol, it is a .22 Ruger Mark III 22/45 target model. I got it today as my birthday present. I did get to shoot 250 Rounds 100 Winchester super x's 50 blaser (super crap leads) 100 CCI Mini Mags (a little more expensive...

This requires knowing the final muzzel velocity which we don't know untill it is fired. The whole purpose of this project is to in the end, understand what factors go into muzzle velocity. That is why this is all an approximation. and seeing as the goal is to understand the principals which...

Deleted because some people don't want it.

for a bullet so light to travel that distance and still be able to kill... that would require a vacuum as at a mile it's almost certainly slowed to it's terminal velocity.

Cool I don't have to do it then, I have QM HW to do.

Theoretical limit for a good 22 lr is 5 miles... in a vaccum, at an angle of 45 degrees. So is it possible, yes, likely ... no. if any body has the co-efficient of drag I can do a more in depth calculation. I'll try it with a roughly aero dynamic CED later tomorrow but I don't have time right...

How, pray-tel did they manage to screw up a 1911

Amen.

A friend of mine wanted me to interject these two: 93R 7mm STW

1911, standard for years for a reason

after doing some more research on .22 ammo I found this: http://www.youtube.com/watch?v=pjbsuJhr_zE I can't really verify it, or tell if it was just that particular gun, but it is a cause for alarm

any comparison to a normal .45, cause the .380s were giving wound profiles like true 9mm.

Cal II or cal III? Cause even I hated cal III. Much more so than differential eqautions. anyway, I think one of previous posts is right about no damage potential being enough to cover for the poor feeding of the round, that might be the reason for it's poor adoption, coupled with the fact...

Good points, That's probably why the frangible was adopted so readily. I've also heard of some new "prefractured" rounds, something similar to frangibles, don't know that much about them.

aparantly they have found service somewhere, not sure on the accruacy of this as that article is several years old.

yup, just because I know alot about them in theory, does not mean I know everything I need to, manufacturing standards can't really be seen by looking at them, and that tends to mess with the reliability. It would have a high co-efficient of drag, a large surface area to transfer energy, and a...

again take a look at the data on the link. It's very simple science people. Easy to understand, and even calculate.
