Subject: Conversion of pounds into inches?
Thomas3    6/1/2006 6:40:44 AM
What is the rough and ready conversion of poinds into inches? I'm normally very "metric", but when it comes to guns I've found inches more amendable to my needs. While we are at it: Range is roughly proportional to caliber - all other things equal? Grenade size weight roughly proportinal to cube of caliber? A standard household 155 mm howitzer range is about 15-20 km range? CEP roughly proportional to range? I know of a lot corrections the artillery man has to make, but I'm looking for rules of thumb (like Roman) that provide a guide to discussion among gunners - whom I've learned are normally more than slightly deaf. Secondly the use is for a fast view of a case/claim to see if the proponent is "shelling marines".

I don't know if I'm butting in at private discussion: But for what it is worth: 30 years ago we saw an old WW2 british training movie illustrating indirect fire with a BREN. What we were told was that that practise had been abandoned, as Vo had increased. Anyway that was the Home Guard, and we generally said that the safest place on our firing range was in front of the targets, as they were so rarely hit - which is somewhat of an exageration. 3/4 of the best had an shooting skill about what you would expect of a regular army unit. 5% were actually very good to excellent.

"... Anyway that was the Home Guard, and we generally said that the safest place on our firing range was in front of the targets, as they were so rarely hit ..." Thats what it is like here in Maryland in Deer season...The safest thing to wear on a hunt is a pair of antlers as opposed to day glow orange camo gear. And if you really want some sport then there's Quail hunting, of course. cheers W

If you included rifles, howitzers, and some portable field guns that could double as mortars then your list expands considerably: 360pdr 240mm/9.5in USA 240pdr 203mm/8.0in USA 210pdr 203mm/8.0in USA 200pdr 183mm/7.2in UK 200pdr 203mm/8.0in USA 100pdr 152mm/6.0in NZ 100pdr 140mm/5.5in UK 96pdr 152mm/6.0in USSR 95pdr 155mm/6.1in USA 94pdr 150mm/5.9in Ger 80pdr 140mm/5.5in UK 60pdr 127mm/5.0in UK 60pdr 120mm/4.7in USA 55pdr 114mm/4.5in UK 53pdr 120mm/4.7in Swe 50pdr 120mm/4.7in UK/Swe/Dut/Ita 48pdr 122mm/4.8in USSR 48pdr 120mm/4.7in Bulg/UK/Ita 46pdr 120mm/4.7in Swe 45pdr 155m/6.1in UK/Jap 45pdr 120mm/4.7in Jap 40pdr 120mm/4.7in Fra/Ger/UK/Ita/Dut 40pdr 110mm/4.3in Ger/Cz 38pdr 104mm/4.1in Aus 35pdr 115mm/4.5in USSR 35pdr 114mm/4.5in UK 35pdr 110mm/4.3in Ger 35pdr 102mm/4.0in UK 33pdr 105mm/4.1in UK/USA/Ita/Fra/Jap 33pdr 102mm/4.0in USA 32pdr 104mm/4.1in Aus 30pdr 102mm/4.0in UK 28pdr 94mm/3.7in UK 25pdr 88mm/3.5in UK/Ger 20pdr 84mm/3.3in UK 18pdr 80mm/3.1in Ger 18pdr 76mm/3.0in UK/USA 17pdr 76mm/3.0in UK 13pdr 76mm/3.0in UK 12pdr 76mm/3.0in UK 9pdr 65mm/2.6in USA/Fra 7pdr 70mm/2.8in Ita 6pdr 80mm/3.1in Ger 6pdr 57mm/2.3in UK 5pdr 57mm/2.3in Ger 3pdr 55mm/2.2in Ger 3pdr 47mm/1.9in UK/Ita/Fra/Jap 2.5pdr 50mm/1.9in Ger 2.5pdr 45mm/1.8in USSR 2.2pdr 40mm/1.6in UK/Swe 2pdr 40mm/1.6in UK/USA/Ger/Swe 1.5pdr 37mm/1.5in UK/USA/Ger/Fra/Swe/Jap 1pdr 40mm/1.6in UK 1pdr 37mm/1.5in USA/Ita/Aus 1pdr 34mm/1.3in UK 1pdr 30mm/1.2in Ger/Jap/Cz/USA 1pdr 28mm/1.1in USA .75pdr 42mm/1.7in Ger .75pdr 30mm/1.2in UK/Fra/Ger/Jap/USA .5pdr 25mm/1.0in USA .4pdr 23mm/0.9in Fra/USSR/Ger
