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". |
