Boy! I didn't want to get into yhis since the last time I opened this can of worms, i ended up with KaKa in my beard.......OK, it's called EDDT (Energy Deposit Dwell Time). We know it exists, but have trouble defining it. It is another reason I hold the velocity on the 250 .44 LFN's down sround 1200/1300 fps.
My brother Clay has two boys and hunt small game with them. All have glass bedded, floted barrel, etc Ruger 10/22's. They had constast complaints about .22 rimfires until I sent them abrick of Remington sub-sonic HP's. Mean Little cartridge. A couple coils off the mainstring for winter hunting.
Test show that the longer a bullet dwells in an object, at below the speed of sound, the more energy the object absorbs...Et Al! All of this is in mico-seconds. Now, don't jump my case!
How you rate this to your idea of killing power is up to you! I will point out that if you run the 250 gr .44 LFN through the wound channel program @ 1100, 1200, 1300, 1400 fps you might be suprise. Look at the wound channel we all know is important. The only difference is penetration. I suggest, that once you have the depth of penetration you want, stop there and consider EDDT. That's all I am going to say on the subject for now!

WOOOPS! Jack...That's what happens when you get old and try to do something at 2:00 in the morning...I missed a number transposing. Not only that but I recalculated the BC and looks like it will come out @ .151....working these form factors are a dilly....I'll edit it! The SD will stay the same and I don't think it will change anything much. Thanks for the check!

PS...Jack what ballistic program are you using? I'm using PCB.....jcg

Jack...Great job!!!! I know dBase III+ well and have it on my computer now. I designed the entire Manatee County Traffic Control System with it! It's still a great old program and my dbf's are still in although I now use dBase4 and compiler...I just path back the III+. In 4 I can set my entry screens and reports a little easier and not have to go through what you did. I really admire what you have done. You can teach anyone data entry, but few can build anything with dBase. My hats off to you. I held, until I retired, a CE1 rating with the state merit system. If you get time change the BC on the 250 LFN to .151 and see if there is much difference. I sent all the co-form data and BC tables that Parker Ackley gave me to Marshall. I hope he will have time to work up BC's for his bullets for the loading manual. I'm going back a check what PCB is set up for. If I could figurea way Iwould get a copy of dBase 4 to you. You could path everything. Talk about Scots...How about Stewart, Robertson, MacTyre, Powell, Dendy, just for starts...All on my late mother's side. Well, my friend, It's 1:28 PM in the Hammock!
Best Regards.....James  (now if I could learn to type!)
