[QUOTE="Pdvdh, post: 1312293, member: 4191"] Never asked anyone to justify their expertise, or value as a human being. I did solicit the description of the relevant experience with recorded bullet velocity from the 223 AR platform, which supports the basis for the expressed opinions. The only caliber and rifle my ES/SD issues pertain to is the 223 AR. Let me clarify: The precision of my bullet clusters on target is completely acceptable across multiple powders and powder charge weights. Accuracy is fine with the 60gr Vmax. The only unique anomaly I experience is much higher ES/SD with this rifle and cartridge, compared to any other rifle and cartridge I have similar levels of effort and experience with. All the other rifles happen to be bolt actions with much larger cartridge capacity, and larger caliber. My AR-15 was born a CMMG MOD4 SA. It has the CMMG 16" factory barrel and carbine length gas action and CMMG bolt and bolt carrier group. Aftermarket mods include the Vltor A5 stock, buffer, and buffer spring kit. A BCM-KMR-A13 free float handguard. A Geissele trigger. A BCM/VLTOR Gunfighter charging handle. I've previously described the prep of the reloaded ammo. ES higher than 50 is the norm when recording velocity of eight or more bullets. I've had some loads with ES exceeding 100! And I've easily recorded more than 200 bullet velocities. If folks are basing ES/SD on three to five shots, they're being misled to a false conclusion. [/QUOTE]
