Thread: 6.5 Creedmoor load development

Just goes to show how much variation there is between different rifles. With my Tikka T3x 6.5 CM 45gns of 2209 will only reach slightly below the neck shoulder junction with Lapua fire formed cases. My overall cartridge length with the 140gr ELD-M is 2.940 and the base to ogive is 2.240 - both measurements seated .010" off the lands. I don't use 45gn 2209 in my rifle but have done so safely.

The best thing I did after I bought my 6.5 Creedmoor was to ditch my old CHRONY as it was very inconsistent in it's accuracy and buy a Labradar. Currently testing the Peterson SR brass too.

Please keep up the excellent reports Wingman - very interesting.
