Matching Pellets to barrels.

[Bardot]

Even if the pellets were 100% identical every time you loaded one it would engage with the rifling slightly differently and that also would cause the difference down range. And as we all know every pellet it as individual as your barrel.

But again those changes would apply to a brand/size of pellet that does shoot consistently accurate.
What is working out and not causing variation when you find a pellet that does not suffer from these issues?

Yes but my question was : If the barrel remains the same between shots (which it does albeit a minuscule change in leading etc.) and you use matching pellets WHY is there no consistance with some and there is with other. To put it another way what makes a good match a good match?

Pellet " A" will not be exactly the same as pellet " B" in its weight or balance, nor will your velocity be exactly the same ( 0 std. deviation), so errors will compound. Add to the mix the fact that a shooter's alignment will never be 100% shot/shot. Long story short, if you & your rifle/ pellet combination can make the magic 1 MOA , Thats all one need worry over.
Consistent velocity( that works)& consistent ammo make the match... If you think sub 12 airguns are a PITA, try having a closet full of centerfire rifles, used w/ differing bullet weights & types, from different makers, for different game species at differing altitudes & weather conditions.

We all know you need to find the pellet that suits your particular gun/barrel in order to get the best consistency. MY question is why ? If you take quality pellets that are consistent in build weight etc and fire them down the same barrel with the same force why don't they hit the target at the same place. ? The components are the same, the driving force is the same but the outcome is different. If you try enough pellets you hopefully find one that suits your barrel and pellets that don't work well in your barrel work fine in others so that equates to swapping barrels. So what is the cause of the miss-match?

It's a lot of things coming together , too much to factor in to be fair . Best thing is when you find a good one , try and buy a load in from the batch or Batch number . The next batch number might not be as good! Very serious International competitors shooting at the highest levels will buy in enough to last . This applies to pistol and rifle , air power or metallic cartages propelled by nitro powder.

Yes it dose indeed. That’s why you must take your time and test every single pellet you can find to get the one that it likes the best and has the least tolerances to how its loaded. And just when you find that golden nugget Pellet, you find you can’t get the same pellet patch anymore and you start over again.
