[QUOTE="Clearlight, post: 1464250, member: 105106"] Regarding Applied Ballistics CDMs , I’m running a Garmin 701 which has the entire library of Doppler tested BCs and CDMs included . So far with several rifles and bullets , the drag models have proven to be very accurate even into and through transonic . In the past regardless of solver , I’ve had to tweak the curve in transonic zone . Long story short , running a BC required separate tracks ( profiles ) for short , mid and ELR ranges . This years KO2M winner was doing exactly that to get solver prediction to match dope . I’m finding that ABs CDMs are eliminating the need for multiple tracks , or truing . It’s a given these days , for best transonic results , you need to spin that projectile as fast as practical for best subsonic performance . For EG , a buddy has a 10 twist 300 NM , mine is an 8 twist : he is fine out to over a mile , but over that my faster twist gives more consistent elevation . Same brand and length barrel , same load just different twist . [/QUOTE]
