sussex lad Posted September 6, 2006 Author Report Share Posted September 6, 2006 Yep got that Is it not possible on some of these programs to input a theoretical load (powder type,amount and bullet type etc)and see the results without firing a shot?

dunganick Posted September 6, 2006 Report Share Posted September 6, 2006 Yep got that Is it not possible on some of these programs to input a theoretical load (powder type,amount and bullet type etc)and see the results without firing a shot? velocity you mean? There is some program that can be used to work out optimum burn times etc.. Airgun BBS is the place to ask. There are some lads seriously into this sort of stuff over there. Of course it has to be working to ask questions there B) Quote Link to comment Share on other sites More sharing options...
deadeye ive Posted September 6, 2006 Report Share Posted September 6, 2006 SL Try this http://www.eskimo.com/~jbm/ballistics/traj/traj.html At first it looks complicated and alot of info is'nt really required to caculate the trajectory .Just read the explanation of terms and away you go Highly reccommended B) Quote Link to comment Share on other sites More sharing options...
sussex lad Posted September 7, 2006 Author Report Share Posted September 7, 2006 Thanks for the replies All off the above require the input of a muzzle velocity, as i don't have a chrono yet how can it be worked out to enable me to use the progs B)?

dunganick Posted September 7, 2006 Report Share Posted September 7, 2006 you should be able to work out roughly what velocity the load should do using the reloading manual Quote Link to comment Share on other sites More sharing options...
Dunkield Posted September 7, 2006 Report Share Posted September 7, 2006 Thanks for the replies All off the above require the input of a muzzle velocity, as i don't have a chrono yet how can it be worked out to enable me to use the progs ? Go to 200 yards and count the time as you pull the trigger to when it hits the target, then divide by 600 to get it into ft/sec - easy B) Quote Link to comment Share on other sites More sharing options...
deadeye ive Posted September 7, 2006 Report Share Posted September 7, 2006 If you want to produce decent drop tables, forget using data on velocity from the loading manuals, its often way out. Get a chrono, you wont regret it. Agreed Anyone know where there is a good quality one going cheap B) Quote Link to comment Share on other sites More sharing options...
