Where did that shot come from?! Same hold, same wind, perfect release we hear it all the time!!
Conformity in BC is critical; the more closely each projectile fired matches its peer in ballistic shape, the more it ensures conformity in drag and the same flight profile to the target.
On average, every 20th round will print way outside your group, in no man's land. Roll the dice, and you may have a run of groups well within your rifle's capability or smaller, and print those precise and accurate groups, but the numbers will always revert to their mean average, and you will have those unexplained shots.
Achieving and maintaining a 10-fps variation in muzzle velocity on your load is achievable. Loading straight out of a box of premium projectiles with basic sorting techniques will improve precision, but won't keep you in the V/6 ring.
With a 10-fps variation in muzzle velocity and zero (0) variation in BC, your vertical spread without any other influence will be 1.98” with a 308 doing 3000 fps (2995-3005), well within the 10” 1 MOA Centre. At 1000 yards
Introduce 3-6% BC variation from batch to batch in ES from a box of premium projectiles; with normal batching, you might shave off 1-2% (ES) at best. e.g., pointing increases BC, but does not address BC conformity; measuring for length brings stability into conformity and does not address BC; weighing projectiles only addresses a minor percentage at best when it comes to BC conformity
With a remaining 5% ES on your projectiles added to your velocity ES, when you get the extreme spreads in both the velocity and the ballistic coefficient align and don’t cancel each other out, you will have a vertical spread of 11” inches and circa 68fps velocity spread at 1000 yards, which is well outside the V/X ring. This is before you add any shooter or atmospheric inputs.
The test shown below has been conducted on multiple occasions, with similar results. The added dispersion is most likely due to equipment, shooter, and environmental inputs.
Target A was shot early morning, still conditions, projectiles rejected from a batch of 1000 premium-grade projectiles; on average, 1 in 10 do not make the cut to go into sub-batches.
Target B was shot using projectiles batched within one (1) deviation of each other, with no runout. With a crosswind component.
