Tokimini, I wasn't offering opinion, I was stating fact. It is a universally accepted principle of ballistic science that bullets in general grow more stable the faster they're driven. To quote Bryan Litz, from Applied Ballistics for Long Range Shooting, Ch. 10, Bullet Stability (p. 150), addressing...

There's no way too much velocity could cause a bullet to loose stability unless the bullet was flawed. Bullets can fail in flight but they essentially explode or disintegrate, they don't tumble. The "1 foot left, 2 feet down" tells me that bullet was tumbling. Whoever you spoke with at Sie...

QuickLoad isn't a logging software, it's an internal ballistic calculator. And a pretty sophisticated one. TucoTom , I do load development by Optimum Barrel Time , which theorizes that you can mathematically calculate the times when the muzzle will be 'quietest,' which, for reasons of accuracy, woul...

I 'spect this is a trade you'll never regret. This group measures .408 outside so .208 center to center but is only a three shot group. Col. Cooper used to say that a 3-shot group is a test of the rifle and a 5-shot group is a test of the rifle man . I don't even bother shooting my Model 12 VL @100 ...

I personally use the Lee Collet and seater die. Not saying the Forrester or Redding dies aren't good cuz I use em in some of my other calibers. Its just so hard to justify spending $80-$100 for dies when the $30 Lee set loads such accurate ammo. +1 I use that same scheme of maneuver with every cart...

For general purpose shooting, hundredths is fine.

No socks but I do find alarming numbers of ball point pens.

That's funny.

Last time I tumbled brass, I ended up with 72 more pieces than I'd started with.




Go figure.

As promised, I finally got round to hauling my rig out into the sunlight to take some pics (but they're still pretty poor). Anyway, FWIW, here's the pieces parts, ready for transport: http://img204.imageshack.us/img204/6075/rcbenchdisassembled.jpg It's held up here by QuickGrips but I keep a milk cr...

Better make that 5mm....

Yoops!

It's metric bullshizzle. Each click (horizontal) is one half of one centimeter (500mm) @100 meters. That comes to 0.197" @109.361 yards. Reduce that to 100 yards and it's 0.18" per click. There's 1.047 MoA per inch @100 yards so times that by the 0.18" per click and you get 0.188461 ....

6.5 mm = 0.2559"

The barrels they used were .256" and .257".

It's actually more often caused by the bullet's lead core melting in flight. This was proved in 2007 in testing conducted by Eric Stecker of Berger Bullets. In a nutshell, first Berger hired scientists at M.I.T., who modeled the firing stresses and confirmed that the bullet's friction against the bo...

What's in Sth Oz Dan's video, I think, is trace, not vapor trail. Vapor trail is weather-dependent and a fairly rare phenomenon. You need a high relative humidity, or a dew point close to the ambient temperature. Bullet trace, OTOH, is caused by the shockwave following the bullet changing the air's ...

A member at the sniper's hide tested his .308 with and without his magnetospeed and found it changed POI @100 yards by about 3 1/2 inches.
