BB Calling Range vs a 15bb Button Shove
Against a 15bb button all-in you call about 25% of hands from the big blind (48 hand classes) — much tighter than at 10bb. You are calling 14bb more into a pot that will hold 31.5bb, so you need roughly 44% equity, and the button is jamming a tighter 36%.

Two things move against you at once when the stack grows from 10bb to 15bb: the price gets worse (you must call 14bb instead of 9bb for a pot that grew by less), and the button's jamming range tightens from 43% to 36%. Both effects push in the same direction, which is why the calling range falls from 35% to 25%.
What still calls is 22+, A2s+, K9s+, QTs+, JTs, A3o+, KTo+, QJo, plus K8s part of the time — every pair and every suited ace survive (22+, A2s+), because they hold up in a raw showdown. What falls away from the 10bb range is K7s–K2s, Q9s–Q8s, J9s–J8s, T9s, A2o, K9o–K7o, QTo–Q9o, JTo: the middling kings, queens and connectors that were only ever calling on price, and the price is gone.
A subtle point most players miss: at this depth the button is also jamming fewer bluffs, so your marginal calls are running into more genuine hands. Do not extrapolate a "he shoves a lot" read from the 10bb chart to a 15bb spot — the same player shoving correctly is shoving a different, stronger range.

FAQ
How wide should I call a 15bb shove in the big blind?
About 25% — 48 hand classes: 22+, A2s+, K9s+, QTs+, JTs, A3o+, KTo+, QJo, plus K8s part of the time. That is far tighter than your calling range against a 10bb jam (35%), because the price is worse and the button's jamming range is tighter.
Why do I call less at 15bb than at 10bb?
Two reasons stack up. You must call 14bb instead of 9bb for a pot that has not grown proportionally, so you need more equity (~44% instead of ~42%); and the button jams 36% instead of 43%, so the range you are up against is stronger. Both say: fold more.

Push/fold tables are a self-computed chip-EV Nash equilibrium (Monte-Carlo hand-class equity with card removal, 25,000 samples, seed 1234; 1bb big-blind ante). Known limits, stated plainly: they ignore ICM, assume nobody overcalls an all-in, and use hand-class rather than exact-combo equity. Exploitability for this stack: 0.036 bb/hand.
