I used my black rapid with my D7000 with the 18-300 and the MB-D11 extra battery and had no issues. When I can gather up enough money I'm getting the MB-D15 for my D7100 with the 18-300 like you got and will be using the black rapid strap.
I believe the MB-D15 has a Mg alloy body, right? I've just upgraded from a D5100 to a D7100, and am looking at third-party grips, but it seems that all but the genuine Nikon unit have plastic bodies. There's no way I'll be hanging my new baby off my BlackRapid strap if there's only some cheap Chinese plastic between it and disaster, so I expect I'll just save up for the genuine article.

A few third party grips are all metal which is a pretty new development. The Nikon is strong enough for D7100's and a relatively light lens like your despite being only 1/2 metal. Any impact or torquing that could break a thick plastic grip will cause damage to your camera and lens. I have 3 mostly plastic grips on 3 bodies with lwnses that are heavier and never have had a problem with well over 100,000 shots in events and other tests of equipment ruggedness and the grips all look better than the cameras (a D90 D7000 and D800) Stan St Petersburg Russia

I've started clipping my BR strap to one of the strap lugs on top of the camera instead of the tripod socket on the grip - because I don't like the feel of all that hardware in my palm when I hold the grip in a vertical position. If I have a large lens with tripod foot mounted, I just unclip from the strap lug and clip to a Black Rapid fastener screwed into a small (1") AS clamp that I can easily move from lens to lens.
The BosStrap folks (similar to Black Rapid) tested the stap post on a Nikon camera to 125lbs before it failed. Though that was a static load failure, considering that it is highly unlikely that I would hang more than 5 lbs from that lug, it would take a force of 25 G's to induce failure. Since I would be unlikely to survive more than 18 G's, I use that configuration without any concern for the strap lug post breaking lose.
Sounds like a significant amount of weight hanging off a tripod attachment point which is designed to have the forces coming from the other direction. Even when I have just the camera and moderately heavy lens, I don't let the combo bounce or swing around too much when hanging from the strap. I'll use my hand to stabilize it while the strap takes most of the weight. If I'm walking rapidly, jogging, or need to jump down from a platform, I take all the weight off the strap.
