jim62,
Since a scope does not need a "label" such as "Big Bore" to work effectively on a large or small bore rifle regardless of length of action, then it is an advertisement that self-limits the expected applications of the scope. In other words, they won't sell as many of them as they could, if they were to sell them without the extra bling.
One very obvious reason to use one on a bolt 22 is that most have a long rear bridge with little flexibility as to ring placement, which makes mounting easier with a longer tubed scope.
A second obvious reason is that the Leupie 3x has the standard (rather than compact) ocular lens, which makes the FOV and eye positioning "feel" larger. I have two 2.5x, an M8 and an Ultralight, and both feel like looking through a tunnel compared to an M8 3x.
Dakoa Deer,
Leupold- not you- is in the best position to actually know who is the main market for the new long 3x. I
guarantee you that not ONE PERCENT of the folks asked to have the long 3x brought back wanted one for a rimfire rifle. Damn sure not at $340 with a 100 yard parallax setting.
Knowing the real market for that 3x, Leupold is not remiss in calling it a "big bore" scope.
A good example of this is SHOTGUN scopes. Same short range parallax setting as most rimfire scopes. Most work perfectly well on a rimfire. Is Leupold wrong to mark them "SHOTGUN"? Same with most "muzzleloader" and "Airgun" scopes.
Actually, since many scope can actually be used on a rimfire rifle, why name ANY scopes with special names?
Names like Rimfire, EFR, Long Range, Varmint,Tactical, DGR ,Big Bore, Shotgun, Muzzleloader,Crossbow ,Airgun etc..
All those special scope designations should be scraped because some rimfire nut may be offended?
