Eddie,
I would have to check the current rules, but if you are asking where heavy bows could be shot, then as I mentioned earlier, there is nothing in NFAS rules to prevent a heavy bow being shot at instinctively at unmarked distance 3D's as the rules stand.
There is only a prohibition on exceeding 300fps which they are not likely to do.
Issues might forseeably arise from there being objections in the case of unsafe shooting or excessive damage to 3D's, but the former applies to all archers and the latter also to compound bows.
In the BLBS which is specifically intended to preserve lawn archery as it was practised in the 19th and early 20thC, there is a limit on draw-weight of 70lb, I believe.
In GNAS, without checking the rules, I believe it may be the same.
Likewise in EFAA, which is primarily marked distance field shooting.
If you are asking what other styles can be shot, in NFAS unmarked distance field shooting, pretty much what you please, though if there is no class for it you may find yourself shooting in a "superior" bow class since most rules are written to exclude a perceived advantage in equipment, not to exclude what might be perceived as a disadvantage.
A lot of folks shoot for fun without being too competitive, but in all classes there is at least a small competitive element, even in PV (primitive) which only became a class of its own quite recently.
Before this I had shot a primitive bow in a variety of "superior" bow classes.
The only thing, perhaps, that prevents anyone from shooting a heavy bow under the existing rules might be a reluctance to see the scores published.
Which if the case is odd, since many of the better longbow field shooters are not afraid of comparison with other bow classes and in fact sometimes post scores that are closer than might be expected on the day to the winning hi-tech bow.
BLBS is primarily two way shooting, Target and Clout, though under the auspices of Hugh Soar there is a limited amount of heavy bow shooting for distance.
In GNAS which is affiliated to FITA (who do not recognise the Longbow*) the choice of bow styles is more limited, being essentially Olympic recurve, Compound Unlimited, Barebow and the Longbow.
Target shooting is their main interest, with some Field archery, Clout, and rarely Flight and Popinjay.
They also shoot indoors in the winter !
Compound Limited (finger release) may now only be shot in GNAS field archery, no longer inTarget.
EFAA is IFAA affiliated and they tend to shoot paper faces at marked distance set in cleared lanes (and since the IFAA also does not recognise the Longbow*) I tend not to think about them too much.

The Longbow being what you blokes eccentrically call an ELB. Whereas we call an American longbow an AFB. or sometimes
a longbow.

Tomahtoe, tomayto, let's call the whole thing off....
