Hi, that's strange. I've checked the program on five different computers, with no problem. Maybe it's a system file missing? Got any error msg? What operative system are you using? I have only Win2000/XP to test the program on. PS. Have updated the installer with all systemfiles needed. Hope this helps. Best Regards Lars-K | |||

1 grain does not equal 648 grams 1 gram does not equal 154321 grains 1 pound does not equal 45359237 grams 1 gram does not equal 2204625 pounds 1 cm does not equal 394 inches 1 ounce does not equal 437500 grains 1 grain does not equal 2286 ounces 1 ounce does not equal 2957353 ml Need I go on? A Sierra 52 grain HPBT bullet at 3700 FPS does not require a 375611.7:1 twist rate, and it definately spins faster than 2.7 RPM. A Sierra 55 grain SBT bullet at 3700 FPS does not require a 366350.0:1 twist rate, and it definately spins faster than 2.7 RPM. A Sierra 85 grain HPBT bullet at 3400 FPS does not require a 344718.7:1 twist rate, and it definately spins faster than 2.7 RPM. And there is NO direct correlation between CUP and PSI. | |||

Hi, I figured out the problems. It's the keyboard layout concerning the "comma-Dot" problem. This must cause the problems since I got total different values on my PC. If I try grains in my program I got.: 1 grain = 0.0648 grams. I'm going to look into the code... Maybe I will make a US version. ******************************* I think I solved the problem. Try to download this program and see if it's working. This is only for the users that don't get any decimals in the program. Download.: DecimalTester | |||

Seems like there are some decimal points missing in those figures....... Like for instance, 1 grain = 0.064860843.... of a gram..... "Bitte, trinks du nicht das Wasser. Dahin haben die Kuhen gesheissen." | |||

Hi, I have fixed the decimal problem in my software for US computers. Just click on the update button and upgrade to version 2.8.0 Regarding the Cup/PSI correlation my algo is mainly taken from recent published data. More data about correlating PSI and CUP can be found in a document by Denton Bramwell Link to the dockument is here.: Correlating PSI and CUP

Lars; I just downloaded it and the update. It works fine for me. I just need to use the comma instead of the decimal point. An interesting program. Thanks...Jim formerly firemanjim registered Mar 2002 | |||

Having written some simple software, I appreciate you effort--thanks. However, there is an error in the temp comversion. When computing degrees C from degrees F, you are short 32 degrees. Hope that helps. Geo. | |||

Thanks Geo. I have checked the temp conversion and I can't find any errors. **** 100°Celsius = 212°Farenheit 212°Farenheit = 100°Celsius **** 38°Celsius = 100°Farenheit 100°Farenheit = 38°Celsius **** Do you get any other values? If you do, it must be the "comma" issue. It's driving Me crazy! | |||

Well, I tried the thing tonight and got these values: F98,6=C37 (Correct) F98.6=C5.30 (Not Correct) Guess that it is the comma issue. Sorry to trouble you. If I had known it was simply a comma problem, I could have used a comma! Anyway, thanks again for the software. Geo. | |||

Here are a couple of other glitches that I noticed. They are likely typos as the word "length" is misspelled. Barrel Calc Page 1x Barrel Twist Page all instances Easy to overlook, easy to correct next time around, too. Geo. | |||
