From: Jonathan Spencer, [EMAIL PROTECTED] What I want is the formula so that I can work out if any of my carbine loads exceed it. It would be nice if someone who understood the formula could write it so I could plug it into Excel. the equation you need is KE in ft-lbs = 1/2 m * v^2 where m = mass in grains and v = velocity in feet/second You need to convert your bullet's weight to mass, and the Excel formula is: =0.5*(Weight_in_grains/(7000*32.16))*Velocity^2 --Jonathan Spencer, firearms examiner "Justice is open to everybody in the same way as the Ritz Hotel."

From: Peter H Jackson, [EMAIL PROTECTED] From: INTERNET:[EMAIL PROTECTED] What I want is the formula so that I can work out if any of my carbine loads exceed it. It would be nice if someone who understood the formula could write it so I could plug it into Excel. Kenneth, If you go to www.jacksonrifles.com and click on the ballistics section, you will find a small Excel spreadsheet which calculates external rifle ballistics using Prof Arthur Pejsa's formulae (usually much more accurate than Mayewski/Ingalls-based tables or programs). The output includes velocity, energy time of flight as well as drop and windage in scope MOA (yes, you can adjust for Nightforce and other scopes or aperture sights whose adjustments are not graduated in true minutes of angle). There is also an output line for a specified "odd" range, for use when hunting with a rangefinder, or at places like Blair Atholl, where the "900" firing point is actually quite a bit less. The sheet was designed for long range varmint hunting and f-class target shooting, so it does not provide reliable drop and windage data for trans-sonic and sub-sonic projectiles (use Pejsa's computer program www.pejsa.com or the modified point mass program at http://www.roadrunner.com/~jbm for this purpose, but you can't easily pack it on a Windows CE computer and take it varmint hunting) However, if all you want is a muzzle energy calculations for a trans-sonic gallery rifle, you can enter your bullet weight and any muzzle velocity and the Excel sheet will give a true figure in ft-lbs.

From: "Royall, Nick E", [EMAIL PROTECTED] the limits for an indoor range were 1410fps ans 475ft/lbs Nick -- Presumably 1,496 ft/lb is the outdoor limit. Steve.

From: Peter H Jackson, [EMAIL PROTECTED] Vince, From the Y2k Bisley Bible, rule 165: Calibre .23" to .455", MV 2,150 ft/sec and ME 1,496 ft lbs, (same as the Army limit for outdoor c-f pistol ranges).

I suppose this excludes one of Peter Sarony's cute little galley rifles in 50 AE and I really fancied one of those (if only to upset Alex :-)). Kenneth Pantling -- You'd be able to use it on a rifle range though. Going by this specification most .22 Magnum loads wouldn't be allowed on a pistol range! Steve.
