I've been useing CGP for a while and I really rate it but I can't fine tune the feckin' thing 'cos I can't find anywhere the BC for the .20 Dynamic PCP5s that I mainly use. I also use their .177 TM1s and I can't find it for them either... Any help would be greatfully recieved Cheers. Quote Link to post

Hey Andy, Si has done three threads now detailing exactly how to find the precise BC for ANY given pellet. Our last post on Registration and Calibration is a perfect guide Just follow Si's instructions and you will have the answer absolutely spot on REGISTRATION & Calibration and also "How to find the BC of a pellet" in a search string will pull up the threads for you I've had 1st hand tuition on this subject and, well youve seen the results buddy Phantom Edited January 4, 2011 by Phantom Quote Link to post
andyfr1968 772 Posted January 4, 2011 Author Report Share Posted January 4, 2011 Thanks, Tony. I think I must have missed the point there but I'll have another look I've been trawling the net trying to find the info but I'm a total techno feckwit!! I can't get my head around mil dots but it's still a very useful guide. Enjoy your hols, mate Cheers. Quote Link to post
Phantom 631 Posted January 4, 2011 Report Share Posted January 4, 2011 Cheers Buddy, I'm now nearing the end and must admit, its beginning to get me down a little The thought of going back to the crap that I escaped from is daugnting to say the least As regards being a TechFeckWit? Well you dont have to use a mildot job to achieve the BC as its POI at your nominal Zero (gotta be precise though) and then move the target out to say 45 meters, keep the same POA and then measure the pellet drop, put that number into CGP (unless youwant to do the complicated algotithm yourself) and CGP will give you the exact BC of the pellet Hope I've helped a little Take care Phantom Quote Link to post
andyfr1968 772 Posted January 4, 2011 Author Report Share Posted January 4, 2011 Thanks, Tony, it makes sense now. I didn't read Si's posts properly but I see what you guys mean. I'd just looked at CGP's list of BCs and not seen them there, then looked at Dynamic's site and they don't list them either, then trawled through the rest of this bloody inter nerd thing and could not find them anywhere..... Tony, mate, you've got to hit the bottom before you'll climb back up and you will. I know, I've been there Cheers........ Quote Link to post
zini 1,939 Posted January 4, 2011 Report Share Posted January 4, 2011 Hi Andy, As long as you accurately know your rifles power output or velocity and input it into CGP you will get the precise BC of that pellet brand if you work it out yourself by firing a rifle registration shoot. This sort of shoot takes weather info into account as well for line and range as well as shoots out any other non standard conditions. If you need any help give me a shout buddy.
