What distance does the vast majority of Eley Tenex get used for in competition? Care to take a guess?
What distance? The very same distance the vast majority of Lapua Midas + and X-Act are used -- 50 yards. Both .22LR BR shooters and 3P shooters shoot 50 yards or meters and they use more of these ammos than shooters in other disciplines.
You're right, and the same can be said for Lapua Midas. These Two companies along with RWS care very little as to what happens with their ammo past 50yds/meters, and don't care at all past 100!
Maybe they'll start caring how it does beyond 100 someday, but it wouldn't be wise to hold ones' breath. LOL.
It's hardly the case that ammo manufacturers don't care how their products do beyond 50 or 100. It's not that they don't want to, or are, indifferent about ammo performance as distance increases.
The majority of lots of Eley Tenex and Match and Lapua X-Act and Midas + have the small ES required for good results at distance. But that's not all that's required for good long distance results.
The thing that's important to remember is that it's difficult to manufacture great numbers of lots of ammo having well balanced bullets that will be able to perform well as distance increases. Such lots do get made, but not each lot of top tier match ammo will have bullets with as small a center of gravity offset as possible. Simply put, some lots of each variety of top tier match ammo have bullets that are better than others as distance increases.
There are lots that have both characteristics -- small ES and bullets that are more perfectly balanced. But these are usually among the first lots to be selected by discriminating BR and 3P shooters, the very people who shoot regularly at 50 yards/meters.
Those shooters who are focused on 100 yards and beyond must be just as discriminating and recognize that competition for limited supplies of ammo is considerable. No matter what make or variety of match ammo, they can't expect to find random lots of any kind that are a good bet to perform well at distance.
Good lots of match ammo will shoot well at 50. But not all lots that shoot well at 50 will shoot well as distance increases. Only some of them will shoot well at 100 and beyond.
