I think it depends on the level of accuracy you are trying to achieve.
As a Short Range Benchrest Shooter, we run into this quite often. But then, we might have a particular bullet that simply will not Agg much better than about .280. But another bullet might get in to that magic sub .200 level.
Back in the mid 2000’s, a certain bullet maker came out with a68 grn boat tail that were phenomenal. I bought 5000 of them and shot very well for a couple of years. If I did not have at least one “teen” agg in a two Gun event, I would be disappointed.
When that 5000 ran out, the next 5000 were no where near as good. In fact, they were so bad that I switched to another brand completely.
What was the difference? Components. Any bullet maker is at the mercy of the components on hand at the moment.
One thing you want to avoid is wasting good components. At this time, 30 caliber Benchrest bullets are close to 50 cents a piece. If you have a mediocre barrel, you have to decide how many good bullets you are going to waste on it. The same can be said for bullets, throwing mediocre bullets down a good barrel seems rather counterproductive.
Other shooting activities might not require that level of precision as both Short Range and Long Range Benchrest.
By the way, most bullet jackets run around .0002 to 0004 in wall thicknes consistency. You can drive yourself crazy trying to ascertain these very small numbers, or concentrate your efforts do the best you can with the things that you do have control over.
