Has anyone else noticed a significant difference in velocity when using different primers?
I’m seeing 60-80 fps increase in velocity when using Federal 205M vs CCI BR4 or 450.
My current .223 load shoots very accurately and consistently but now worried I may be pushing pressures.
23.4 grains of 8208 under 80 ELDm. 24” barrel bolt gun. Lapua brass and federal 205M primer. This load should be around 2800 but instead I’m getting just over 2900.
Next step is to drop powder charge, unfortunately I have about 400 rounds already loaded.
