While an interesting discussion. It is a daunting task to complete a complete comparison. Certain aspects, brass thicknes, can be quantified, to point. But, does it make a meaningful difference?
Every aspect of the ammo being fired, adds another variable
One unknown, with Vista being a major supplier, is specs. Vista manufacturers Remington, Federal, CCI. That doesn't mean the specification is the same. Within each brand there are different levels of ammo, with different specs, but could have the same headstamp. A particular barrel/gun will love one and hate another. Another gun, of same make and model even, may be the opposite, because it is different.
For example, one machine is plating bullets. Final testing, the jacket thickness is tested.
Load X will have the a spec of .020, + or - .002 (for example)
Load Y spec is .018, + or minus .003
Load Z spec .016 + or minus .004
As can be seen, there is overlap,but 2 other factors come into the equation.
Load Z requires 5 million units, being the least expensive, bulk ammo
Load Y needs 2 million units, more expensive
Load X gets 1 million, Match, LE, SD. Most expensive. Premium ammo.
The same thing holds true for brass. Which coming off the same machine, will have the same headstamp.
Then, a reloaded picks up a 5 gal bucket of brass, sorts by headstamp, measures that brass, by weight, wall thickness and finds a variation of .010 and BELIEVES the quality is very inconsistent.
Same thing happens with powder. Large batch is made. That batch just happens to fit into a very narrow spec, it becomes XXX and is sold to reloaded. It just misses spec and becomes the bulk powder used for factory loading. Lot# becomes VERY IMPORTANT.
I have 46 years working in different industries, dealing with specs.
